Do you use these sensors in your smart home? I'm curious to hear! Learn more about Panasonic's IAQ solutions: bit.ly/reedsolar2 Thanks to Panasonic for sponsoring a portion of this video.
Achim from AirGradient here. Many thanks for reviewing and recommending our monitor! Very appreciated. I'll try and answer any questions that might pop up in the comments below.
@@SmartHomeSolver yes sir I have a few Airthings sensors. I stopped buying them though because I the multiple apps thing is strange, and the price is a little out there. I do love them and they have really opened my eyes (even though I’m an HVAC guy and have always had air quality on my mind). I just think Airthings might possibly be price gouging a bit.
I love my airthings sensor. It measures everything and is viewable as a trend over time. This is especially helpful for radon because it can fluctuate throughout the year drastically. It kills 21,000 people a year in the US. A level above 4 pCi/L is equivalent to smoking 8 cigarettes a day.
I would like to incorporate some motion sensors in my house, however only on specific days of the week. Some days I don't want motion triggering any lights. Is there a way to only have the sensors active on specific days of the week (and specific times as well)?
Smart Home Solver, We really appreciate you showcasing our tiny multisensor! Just a quick note, the one in the video is actually our Apollo MSR-1 mmWave CO2 multisensor. This was our first sensor and after some community feedback we've actually made an updated version called the Apollo MSR-2. It has the same functionality but it's even smaller! It still uses the LD2410B mmWave sensor and the SCD40 CO2 NDIR sensor. We do offer the Apollo MTR-1 like you mentioned but it uses the LD2450 which was a community requested sensor. We apologize for not getting you our true air quality Apollo AIR-1 sensor but will send you one ASAP. It is made for ESPHome and uses the SEN55, SCD40 and MiCS-4514 sensors. We will be in touch to get you all of our sensors. Again, we really appreciate the shout out and are happy to answer any questions! Best, Justin Apollo Automation

Apollo sensors are awesome! I have an Air-1 on each floor and an MSR-2 with CO2 in the bedrooms and office. Very affordable too. The only small issue I had was it showing crazy high methane levels in the Air-1 a few times, but it looks like Apollo engineers are aware of the issue.
Don't you think you're letting Generac Inc & whoever it chooses to sell your data to (that it legally owns) a little too high up where sun don't shine?
Very important subject. AirGradient, Airthings, Apollo, and Aranet - and perhaps others on this list - use a nondispersive infrared (NDIR) sensor. NDIR is the gold standard, and I really think it should be an explicit table dimension. All sensors are not equal. And watch out, some manufacturers claim NDIR sensors but don't actually use them! I personally have ecobee Premiums, and an Aranet4 on my desk, and an Airthings View Plus (currently) in my basement. The ecobee sensors are mid, but it's something. The simple and portable Aranet4 surged in popularity during the pandemic after it became clear that CO2 levels are a great proxy for general air stagnation, and thus airborne risk.
@@ApolloAutomation We should probably clarify that the SCD40 uses photo acoustic NDIR versus most other NDIR CO2 sensors use light spectroscopy. We tested both methods some time ago and wrote on our blog about it. Indoors (and within typical temperature and humidity levels) the two methods perform very similarly. So in normal conditions, the Apollo monitor should give similar results, however more extensive tests e.g. measuring CO2 outdoors showed that light NDIR is more accurate. The best ones are probably made by SenseAir which we use in the AirGradient and also used in the Aranet (not sure about the other brands). (Achim from AirGradient)
If anyone buys a sensor that makes claims for VOCs or CO2, a quick test is to open a carbonated beverage near the sensor. A CO2 sensor should respond instantly. For VOC, open a bottle of isopropyl alcohol and the sensor should respond. Some cheap sensors claim they detect VOCs when they really only detect CO2.
Radon detection is key if you’re in an area with lots of rocks, especially ledge near the surface. It can cause lung cancer and it can be treated with a mitigation system (essentially a pipe and fan that pull radon and other gases from under your house and release them safely above it) so make sure you use a radon detector!
Great video! I have always looked for sensors in my house but there are so many that it overwhelms me hahaha the last thing I got and now I am a big fan is my Vionentus VN100 wallet
Yes, bro, the same thing happens to me, there are so many models that I get confused. But I would like to know about what you mention... does it have an airtag slot?
@@KrisH544_d Dudee, I'm in love with it. They are so elegant that when I take them out I feel like I'm in a movie from the 20s. It also has RFID technology to protect dataa
Dont fuck around with radon. If you live in a zone that has elevated radon I would strongly suggest the airthings sensor because it gives you a trend over time which is way more accurate for radon detection.
Ya, he glossed over RADON as if it was nothing. It is the second leading cause of lung cancer. Check if RADON is prevalent in your area then, if it is, everyone should have their home tested. You can't see it or smell it.
If you're in an area with increased risk of Radon, your home will often have Radon mitigation of some sort. Having a Radon sensor can be very beneficial to track the level and determine if your mitigations are failing. Radon is a radioactive gas, and only occurs in areas where there's deposits of certain radioactive elements deep underground ground. It seeps up through your foundation. It is very dangerous when it collects, which did happen in older homes, but can be more of an issue as modern homes are more airtight.
Great video, thank you! Radon sensors are very important if your area has radon. Radon has a tendency to spike out of nowhere, so it's a good idea to ventilate your basement when it happens. Also, if you have a radon mitigation system, a sensor is a must because the system may fail, and you will not notice that.
Especially because radon is radioactive radiation and can cause cancer.

Radon meassurement can spike during winter if you live in an area with snow. When snow is packed around the house, the radon as a light weight gas, finds the easiest way up. If that is through your house, you really need a radon detection system.
Radon does vary quite a bit over the course of the year. Having that information could be particularly useful if you have a system that removes it and has the potential to fail, or if you plan on adding a system soon so you have before and after Data to compare.
I bought my Dad a NetAtmo device it had one sensor outside one inside. One Christmas there were eight people in a 15'x15' living room of a small bungalow. No HVAC in the house, all windows closed because it's winter in Canada. I felt lethargic, and everyone else seemed a bit tired. I checked and the CO2 was at about 2,000ppm! I opened a window -10C or not it had to be done. Myself and everyone else immediately felt better it's amazing how instant of an effect it is.
The video says at 9:43 that the IKEA VINDSTYRKA's VOC measurement doesn't show up in Home Assistant. It does if you're using Zigbee2MQTT. I know that it didn't used to with ZHA, don't know if that's still the case though (I use Z2M, not ZHA).
Very nicely timed. Recently got the Airthings sensor after we had a mold issue that caused my wife asthma issues. Found out our CO2 is terrible, explaining headaches at home
Yeah! I have two Air-1's one with gas sensor - they're awesome! Air-1 is not as user friendly as other sensors in this review (no screen), but it's more affordable, smaller and has better sensor (10 yrs life)
Radon happens any place you've moved earth to build. It's more prevalent in places with basements. It is a radio active gas as I understand it. Living in a house for ~30 years with a reading of 4.0 or higher is the equivalent to 100 extra chest x-rays (or so I've been told)
We’ve had CO2 sensors in the home for a long time, and another outdoors. We use an automation that forceably kicks on the home ventilator (and hvac fan) if any room tops 1000ppm, then runs for an hour. Really has helped. The outdoor sensor prevents the ventilator from running when the outdoor air is bad. Another automation runs the house fan to clean the air if the PM2.5 gets too high and warns it not go outside.
Finally a sensor that can measure sound!! I've been wanting to keep track of decibel levels but couldn't find any off the shelf solutions. My neighbour complains that I'm noisy, but I really don't feel that I am, so would like to measure decibel levels and keep logs.
Since I have mostly an Amazon smart home, I use the Amazon smart home air quality monitor. It's able to measure air quality inside you mentioned, and it has the ability to run routines in the alexa. Great for those who might not be home assistant users. Usually, I use a fan routine and announce on my echo speakers.
Standalone air filtration units with HEPA filters and (crucially) active carbon filters can scrub VOC's. Obviously the HEPA filter scrubs particles. Also, Vindstyrka means wind strength directly translated, so Windspeed, in case you were dying to know.
From an engineering perspective, Co2 buildup means inadequate ventilation in the room by default. Probably because of a lacking ventilation plan in the house, so something needs to change clearly. All rooms in a building should have enough ventilation either natural or mechanical, but more ventilation means more heat/cool loss. Automating it to make it only refresh the right amount of air needed to keep the air clean will result in less unneeded heat/cool losses and thus improved efficiency. This video gave me much inspiration. I like it! As well as the good acting of you and your wife.
As usual, great comparison! I just got the air gradient a couple of weeks back and loving it. Rich insights with data about what we can’t see in the air! Only issue with air gradient so far is that the leds and display won’t turn off at night and that becomes an issue as they are way too bright. They do have an option to turn them of on their cloud portal but doesn’t seem to work at the moment. I’ve raised a ticket with them a few days ago but no response. Their equipment is great quality but as any new product, still minor teething issues here and there!
Ok, problem solved in 6 days! Great support! According to the support person, when you enabled the Home Assistant integration, it changes one of the configuration parameters on the device to only accept configuration commands locallay (i.e. not from the cloud). a simple http put command (curl -X PUT -H "Content-Type: application/json" -d "{\"configurationControl\":\"both\"}" airgradient_xxxxxxxxx.local/config (replacing xxxxx with your monitor's serial number) via terminal fixes it straighta away.
I have one in my bedroom and am pretty happy with it. It's small, is easy to read, and looks good. It does work with Home Assistant, but I've had trouble with reliable connectivity to my Zigbee network for some reason.
I recently built a CO2 sensor for my home office using an scd40 and esp32 as i was getting headaches and losing concentration. It turns on the fan and I can see the data on a home assistant tablet at my desk, and now i see your video doing exactly the same thing with ready made products
Having an AirThings radon detector and monitoring it for the past 2 years, I can say it is not true that Radon is just there or is not. I see tremendous variations based on whether my air exchanger is running or not. If it is not running for a while, radon spikes. If it is running, radon remains to a safe level. I automate my air exchanger based on Radon, CO2 and VOC levels.
Thank you for this video! I use the Netatmo weather station (indoor and outdoor) and lately it's been reading very high on the CO2. I've been looking for something to act as a sanity check and help me determine if the unit is bad or if all of a sudden over the past few months, our house (guests included) have been putting off more CO2. The problem is, so many of these devices are very expensive just to validate if something is broken. On the other hand, it may be a worthy investment. I do really enjoy your videos and content, please continue.
It is a radar target tracking card for the LD2450 that was made by the community. I cannot post any links or the comment will be removed. Sorry! Best, Justin Apollo Automation
I have the AirGradient, the Apollo AIR-1, and the ecobee. The ecobee is always way off and (after a call to their support verified) simply provides estimated values. I actually purchased the other sensor because the ecobee numbers raised so many concerns. A big concern in our area is radon and only the Airthings monitors those values AFAIK.
Achim from AirGradient here. Thank you for your support! The Ecobee does not measure CO2 directly but estimates it from its VOC sensor. This is highly inaccurate and not recommended at all. This is why it's important to use an NDIR CO2 sensor that measures the CO2 molecules directly.
I've been using the Awaire Element. It works immediately with Home Assistant without special drivers. Seems pricey, but since it was used for a while in some crypto computing thing, tons of people have been selling them used on eBay for $99 or less. Sensors are commercial quality rather than consumer/basic level.
@@jeffkirk4761 I’m using a few Qingping Air Monitor Lites into HA, as well as some Awair. I have a few Mila air filters that have great sensors built in too.
I got the Apollo Air-1 and now it’s automating a 500 CFM dust collector fan in a large maker space. It’s awesome. But, it cost over $100 all in with shipping. I got a bunch of the Sensirion SENS55 sensors and ESP32 boards but now I’m lost on how to get them working together. If anyone has any direction on that it would be completely awesome :-). Thanks for turning me on to this Reed!
In a video about air quality, i don't see any plants in the house! Might be a solution to your problem thats a lot easier than running fans and automations.
In Germany: yes. In the rest of the world, HVAC (optionally with heat exchange) is getting more and more common. I adjust the speed of my HVAC to keep the air quality within acceptabel levels while not sucking out too much hot air in the winter (or cool air in the summer)
Ecobee doesn't measure CO2, it approximates it (you can look it up in their docs). And in my experience, it does this poorly. Get yourself an Apollo Air1. Huge miss that it wasn't even reviewed in this video as it's way better than any of the others mentioned.
Great video. A lot of useful sensors I also do not expect thay I needed. Btw In your intro, the solutions for your productive problem is add natural light in your room. decent amount of Sunlight during work room add more productivity and energy. That’s why Apple Park HQ want office to have the most natural light as possible. Hope this help.
Reed, time to get some plants for your office. You can for sure cut down the number of events you have pretty easily and then you can review various watering and water monitoring sensors for us. Win win.
Reed, there's this guy on youtube that tested this theory that plants have any chance to offset your co2 production in a sealed room and the conclusion is that it's all bullshit because you need way more plants than would fit in any one room for any one person. But you could test this out with a sensor for sure.
The devices you mentioned measure for co2, but the drowsiness that kills your productivity is not caused by the high level of co2, it is the low level of o2. The human body converts oxigen to carbondioxide.
Another air quality metric to look out for, especially in colder climates, is the humidity. My apartment is very well ventilated meaning CO2 is not a big issue, but as the temperature outside drop below like 10C, the air can't hold as much humidity, leading to lower relative humidity inside. This can cause sore throats, headaches and increased risk of spreading airborne diseases such as a colds. Many smart thermometers comes with hygrometer, and if you see the humidity drop below 30% you probably need a humidifier.
aww man, cant believe you just got into those. i'm doing this for 3 years now. using awair (recomending it) air sensor which gives out local webservice with co2,voc, pm, hum, temp and using that to command my MVHR with modbus auto-magically. it is awesome, automatic boosts in ventilatiin if something goes to high quickly or just increasing the pace when needed.
An important and well-researched video, thank you @smarthomesolver. Inspired by your effort, I bought an Ecowitt WH46 air quality sensor and integrated it with my Hubitat network. I have already learned that I need to open the window more often in my work-from-home office, based on CO2 levels.
Interesting video. Would love to see a follow up video about air purifiers that have these sensors already built in AND are usable in Home Assistant (hopefully locally).
Great question and that was an awesome video! I cannot speak for the other sensors but our Apollo Automation devices are all fully supported in HA/Made For ESPHome, local and open-source. They do not require an internet connection or monthly subscription to work. Let us know if you have any questions! Best, Justin Apollo Automation
I have a HRV that's always running since its a new build so its built airtight. Or the windows are opened a tiny crack to get some fresh air and ventilation before i get cabin fever. Living in Vancouver is a plus since the climate is relatively mild. There's something about the fresh air hitting your face that feels better than circulated air from an HRV, AC, etc
Pretty cool, have you seen any that can detect natural gas? In my area we use natural gas for our house heating up in the attic. We also get a lot of lightning storms. There are always a couple of houses every year that get the unfortunately combo of a gas leak and lightning strike that makes their house catch fire. There are even more that just have a slow leak that fills the attic with gas requiring the fire department to rush out. Having something up there that could sense it and warn you would be really awesome.
Hi, any more options for a co meter? I would like to put one close to the fireplace. I love that all your options had home assistant and are mostly wired. Do you also have recommendations for fire alarms? maybe a system that work interconnected, if one goes off more of them go off?
Nice chart! I wish there were more options in terms of Radon sensors. It's very prevalent where I live in Oregon. Samsung has ERVs as well but I think it's either exclusive to other countries or just not advertised here.
An even more over-the-top and more expensive sensor is the 'air-Q pro'. I bought one, loved it, and bought 3 more. It works great and has native integration with Home Assistant. You can see the output of those sensors in this shot from another Smart Home Solver's video: th-cam.com/video/EBT1mnLMPmI/w-d-xo.html (The charts were created using the mini-graph-card) The Air-Q Pro can detect: - Oxygen - O2 - Carbon Dioxide - CO2 - Carbon Monoxide - CO - Particulate Matter - PM1 + PM2.5 + PM10 - Nitrogen Dioxide - NO2 - Hydrogen Sulfide - H2S - Ozone - O3 - VOC - Temperature - T - Relative Humidity - ρrel - Air Pressure - p - Noise - Lp (averages over 20 minutes)
I have been using the Milesight sensors myself... AM100 series has temp humidity and CO2, but the AM300 has also VOC, PM2.5, PM10 and O3 (plus pressure, light and has a small PIR on the front). Only downsides are that they might be a bit more pricey, and they use LoRa so you need a LoRa gateway and get the data via MQTT.. but on a positive note, they all look much nicer than those to be fair 😊 look at the AM319 and the super nice paper display... Hard to beat
@smarthomesolver , I have the govee air quality monitor and it’s linked to my govee air purifier, I have it set whenever pm2.5 reaches x amount it turns on high speed until the air quality is set to the range I set , I have 4 of these in my home one is in the dining room area so whenever I cook/fry it goes on the highest speed until the air quality is ok .
It is cheap. US$40 on the web page but it would be good to have CO2 as well. Are you using Home Assistant? Does it connect using Bluetooth or do you need Wi-Fi? TIA
I have ERV ventilation at home and since many years I made an automation with HA: the level of CO2 are monitored in each room and thr level is kept constant
Dude I’ve been telling people this for years!! My friends and work colleagues just shrug it off and think I’m special. 😂 Then when I show them my Airthings data from BEFORE & AFTER my ERV install they know I’m Telling the truth!! Also, I automated my ERV with one of those Aqara Relays and it worked perfectly! 😁
Learned from an unfortunate experience in a NYC hotel, bed bugs are attracted to CO2. By having a fan that pushes the CO2 away from your head and your bed, you are also removing the bed bugs ability to find you should you bring some home from a vacation. They would eventually just die assuming you have appropriate pest control.
It seems like the next logical step after monitoring air quality is to look at air filters. I know it's not necessarily smart home related, but there are cheap, DIY air filters called Corsi-Rosenthal boxes (a.k.a. CR boxes) that can outperform expensive HEPA filters. To make it fit the smart home channel a little bit more, you could put it on a smart switch to turn on when your monitor detects the air quality is too low.
My Dyson air purifier has taught me how bad the air can be, has the PM sensor etc. When you cook smoky stuff you can just see those numbers go through the roof. I was at a house the other day and they had some sort of whole house fresh air exchanger thing in the basement, that might be the way to go.
Thanks for the great video Reed. Another video that will end up having me spend money on the smart home . . . . which is inversely related to the magic in the bedroom 🤣
Achim from AirGradient here. We currently do not charge anybody. Wven after the free period or 1 or two years they have unlimited access. We might charge in future a very low amount for premium features but will always keep a comprehensive free tier. We are also open source and it is easy to send our data to any other platforms like Home Assistant and not use our cloud at all. So you are not locked-in into our platform at all.
No but want one that dector of mold and cigarette. I live in an apartment With people who smoke and it comes in through the windows. Also bad neighbor smells Any ideas?
Thanks for your comment! Our outlet mounts were created based on community feedback as a way to mount your sensor without needing a cable. Our outlet mount and 90-degree adapter allow you to plug the sensor directly into a wall wart or receptacle. We're happy to answer any questions! Best, Justin Apollo Automation
Agreed, and I don't think people should be ignorant of it in an area that has high radon levels. I'm from Iowa, and we're evidently one of the states with the highest radon levels. I invested in an Airthings Wave Plus so that I at least know what I'm being exposed to in the long term. It's not even crazy expensive for that model since it is bluetooth-only. That's not a downside to me since it means it can integrate locally with Home Assistant (no cloud dependencies).
Yep, for those who don't know, Radon is an invisible odourless gas which is produced when some rocks break down over time, so it depends on the geology under your house as to whether it's an issue for you. It's emitted from underground, and outside it just dissipates harmlessly into the air, but it can come through the floor-slab of buildings, and it's carcinogenic, so if high levels of radon build up inside your house (or office), occupants can develop lung cancer over time. I live in Ireland, where the geology of most of the country means it's an issue (two people a week die of radon-caused lung cancer in a population of 5 million). New houses have to have a radon barrier in the floor slab by law, but older houses like ours don't have one. Our original test readings, using the Airthings Radon sensor, were nearly 400 Bq per M3 (over 100 means you should take mitigation measures) so, during a remodel, we installed MHRV (Mechanic Heat-Recovery Ventilation) which changes the air every few hours, but uses a heat exchanger to recover the heat (or coolness) of the exiting air to heat (or cool) the fresh, incoming air. Our radon readings now range from 20-80 Bq/M3 (depending on the season, more radon is produced in wintertime). MHRV also keeps internally-produced CO2, VOC and PM levels low.
I'm an Anaesthetist in the UK (aka Anaesthesiologist). I am very skeptical about the CO2 claims that people Keep making. The CO2 level in your body is not regulated by your environment but by the pH of your cerebrospinal fluid, if the CO2 in your environment rises - you just breathe more, dropping your CO2. The meta analysis that this claim seems to be originating from has some weird results, likely due to publication bias. It shows that congnition drops with 1500ppm but drops *less* with 3000ppm. More likely that you lose concentration after working for a while, which is also when the CO2 is high because you've been in the room for a while That being said CO2 may be a reasonable surrogate marker for the "freshness" of room air - with stale air containing more harmful components.
Thanks for your comment. Is it not true though that in a closed bedroom with two people sleeping the CO2 will rise and as you say require the occupants to breath more. If one of these people has sleep apnea or other breathing issues, a sensor that can detect the rise in CO2 and trigger some fresh air to be brought into the room would be beneficial.
@@MichaelBabcock Yes, I know it sucks being poor. But $650 on a new resmed 10 with zero interest paid over 10 months is not much for something a little important like, you know... sleeping.
I've been using Netatmo for some years now, it the indoor sensor have CO2 reading and I first thought it was a gimmic. It constantly showed above 1k ppm. Turns out, it's sensitive to what you place it close to. I had hidden ours in a mocca plant, and.. that where apparently not so great for readings of CO2.
I would say that the light should turn yellow when the CO2 level goes past 700/750ppm, and red after 1000ppm. Fun fact: Over 100 years ago, in the 1920s, it was recommended in England that infoor CO2 levels should be kept below 1000 ppm to ensure good air quality and health.
@@Bremend that's fair, but I have no interface other than alexa and the LED light on the front. As an Alexa fan for many years, it's sad to see how bad the overall ecosystem has gotten

Totally agree with this comment. The eCO2 sensors are not in the same category. Better than nothing maybe but just barely.
If anyone buys a sensor that makes claims for VOCs or CO2, a quick test is to open a carbonated beverage near the sensor. A CO2 sensor should respond instantly. For VOC, open a bottle of isopropyl alcohol and the sensor should respond. Some cheap sensors claim they detect VOCs when they really only detect CO2.
Radon detection is key if you’re in an area with lots of rocks, especially ledge near the surface. It can cause lung cancer and it can be treated with a mitigation system (essentially a pipe and fan that pull radon and other gases from under your house and release them safely above it) so make sure you use a radon detector!
Many old houses in some parts of the world used a type of light concrete which emits radon gas as well.
Great video! I have always looked for sensors in my house but there are so many that it overwhelms me hahaha the last thing I got and now I am a big fan is my Vionentus VN100 wallet
Yes, bro, the same thing happens to me, there are so many models that I get confused. But I would like to know about what you mention... does it have an airtag slot?

One of the best gifts I gave my brother when he went to Paris was that one, his friends always comment that it looks cool
Dont fuck around with radon. If you live in a zone that has elevated radon I would strongly suggest the airthings sensor because it gives you a trend over time which is way more accurate for radon detection.
@naidturner7190partially, the measure is Radon
Ya, he glossed over RADON as if it was nothing. It is the second leading cause of lung cancer. Check if RADON is prevalent in your area then, if it is, everyone should have their home tested. You can't see it or smell it.
Radon is a radioactive gas, so no he did mean Radon but it gives out radiation yes
If you're in an area with increased risk of Radon, your home will often have Radon mitigation of some sort. Having a Radon sensor can be very beneficial to track the level and determine if your mitigations are failing.
Radon is a radioactive gas, and only occurs in areas where there's deposits of certain radioactive elements deep underground ground. It seeps up through your foundation. It is very dangerous when it collects, which did happen in older homes, but can be more of an issue as modern homes are more airtight.
Radon has to be very high in combination with cigarette smoking. Everything else is a lie
Great video, thank you!
Radon sensors are very important if your area has radon. Radon has a tendency to spike out of nowhere, so it's a good idea to ventilate your basement when it happens. Also, if you have a radon mitigation system, a sensor is a must because the system may fail, and you will not notice that.
Especially because radon is radioactive radiation and can cause cancer.
Radon meassurement can spike during winter if you live in an area with snow. When snow is packed around the house, the radon as a light weight gas, finds the easiest way up. If that is through your house, you really need a radon detection system.
Radon does vary quite a bit over the course of the year.
Having that information could be particularly useful if you have a system that removes it and has the potential to fail, or if you plan on adding a system soon so you have before and after Data to compare.
My house spikes to dangerous levels if I cover the vents to protect my water pipes from freezing in my crawlspace during the winter. 😢
I bought my Dad a NetAtmo device it had one sensor outside one inside. One Christmas there were eight people in a 15'x15' living room of a small bungalow. No HVAC in the house, all windows closed because it's winter in Canada. I felt lethargic, and everyone else seemed a bit tired. I checked and the CO2 was at about 2,000ppm! I opened a window -10C or not it had to be done. Myself and everyone else immediately felt better it's amazing how instant of an effect it is.
The video says at 9:43 that the IKEA VINDSTYRKA's VOC measurement doesn't show up in Home Assistant. It does if you're using Zigbee2MQTT. I know that it didn't used to with ZHA, don't know if that's still the case though (I use Z2M, not ZHA).
Very nicely timed. Recently got the Airthings sensor after we had a mold issue that caused my wife asthma issues. Found out our CO2 is terrible, explaining headaches at home
Odd that the Apollo AIR-1 wasn't a part of this comparison but the MTR was, which is more a presence sensor than an air quality sensor.
Thanks for the mention! We are reaching out and will work on getting one to him.
Yeah, totally. That was my thought too!
I just got one of those AIR-1 a month ago and I love it, highly recommend
Yeah! I have two Air-1's one with gas sensor - they're awesome! Air-1 is not as user friendly as other sensors in this review (no screen), but it's more affordable, smaller and has better sensor (10 yrs life)
Radon happens any place you've moved earth to build. It's more prevalent in places with basements. It is a radio active gas as I understand it. Living in a house for ~30 years with a reading of 4.0 or higher is the equivalent to 100 extra chest x-rays (or so I've been told)
I live in NJ and Radon is continously measure on the basements. It comes from underground and can be carcinogenic.
We’ve had CO2 sensors in the home for a long time, and another outdoors. We use an automation that forceably kicks on the home ventilator (and hvac fan) if any room tops 1000ppm, then runs for an hour. Really has helped. The outdoor sensor prevents the ventilator from running when the outdoor air is bad. Another automation runs the house fan to clean the air if the PM2.5 gets too high and warns it not go outside.
Finally a sensor that can measure sound!!
I've been wanting to keep track of decibel levels but couldn't find any off the shelf solutions.
My neighbour complains that I'm noisy, but I really don't feel that I am, so would like to measure decibel levels and keep logs.
Since I have mostly an Amazon smart home, I use the Amazon smart home air quality monitor. It's able to measure air quality inside you mentioned, and it has the ability to run routines in the alexa. Great for those who might not be home assistant users. Usually, I use a fan routine and announce on my echo speakers.
Standalone air filtration units with HEPA filters and (crucially) active carbon filters can scrub VOC's. Obviously the HEPA filter scrubs particles. Also, Vindstyrka means wind strength directly translated, so Windspeed, in case you were dying to know.
From an engineering perspective, Co2 buildup means inadequate ventilation in the room by default. Probably because of a lacking ventilation plan in the house, so something needs to change clearly. All rooms in a building should have enough ventilation either natural or mechanical, but more ventilation means more heat/cool loss. Automating it to make it only refresh the right amount of air needed to keep the air clean will result in less unneeded heat/cool losses and thus improved efficiency. This video gave me much inspiration. I like it! As well as the good acting of you and your wife.
I like the quality of the sensors used by Aranet. A few years ago when that Vulcano exploded, I could see the shockwave in the air pressure graph.
I find this video a breathe of fresh air...😉
You leave the door open again!
Don't close the door on your way out.
As usual, great comparison!
I just got the air gradient a couple of weeks back and loving it. Rich insights with data about what we can’t see in the air!
Only issue with air gradient so far is that the leds and display won’t turn off at night and that becomes an issue as they are way too bright. They do have an option to turn them of on their cloud portal but doesn’t seem to work at the moment. I’ve raised a ticket with them a few days ago but no response. Their equipment is great quality but as any new product, still minor teething issues here and there!
Ok, problem solved in 6 days! Great support! According to the support person, when you enabled the Home Assistant integration, it changes one of the configuration parameters on the device to only accept configuration commands locallay (i.e. not from the cloud). a simple http put command (curl -X PUT -H "Content-Type: application/json" -d "{\"configurationControl\":\"both\"}" airgradient_xxxxxxxxx.local/config (replacing xxxxx with your monitor's serial number) via terminal fixes it straighta away.
Any reason why you didn't check out the Aquara TVOC sensor? I would love your thoughts on it.
I have one in my bedroom and am pretty happy with it. It's small, is easy to read, and looks good.
It does work with Home Assistant, but I've had trouble with reliable connectivity to my Zigbee network for some reason.
I recently built a CO2 sensor for my home office using an scd40 and esp32 as i was getting headaches and losing concentration. It turns on the fan and I can see the data on a home assistant tablet at my desk, and now i see your video doing exactly the same thing with ready made products
I took IKEA VINDRIKTNING, and put ESP32 in it, have pm2.5, temp/humidity/pressure, and mmwave ld2450 (same sensor as in Apollo). Neat. :)
Maybe you can tell/show us how you did this and for how much. 👍
Having an AirThings radon detector and monitoring it for the past 2 years, I can say it is not true that Radon is just there or is not. I see tremendous variations based on whether my air exchanger is running or not. If it is not running for a while, radon spikes. If it is running, radon remains to a safe level.
I automate my air exchanger based on Radon, CO2 and VOC levels.
I got a CO2 sensor for my desk years ago, the first time I plugged it in the light went red and an alarm went off, safe to say I needed one.
Thank you for this video! I use the Netatmo weather station (indoor and outdoor) and lately it's been reading very high on the CO2. I've been looking for something to act as a sanity check and help me determine if the unit is bad or if all of a sudden over the past few months, our house (guests included) have been putting off more CO2. The problem is, so many of these devices are very expensive just to validate if something is broken. On the other hand, it may be a worthy investment. I do really enjoy your videos and content, please continue.
What is that card Reed shows when talking about the Apollo sensor (11:45)? I would love to use it
It is a radar target tracking card for the LD2450 that was made by the community. I cannot post any links or the comment will be removed. Sorry!

I have the AirGradient, the Apollo AIR-1, and the ecobee. The ecobee is always way off and (after a call to their support verified) simply provides estimated values. I actually purchased the other sensor because the ecobee numbers raised so many concerns. A big concern in our area is radon and only the Airthings monitors those values AFAIK.
Thanks for your support!
Achim from AirGradient here. Thank you for your support!
The Ecobee does not measure CO2 directly but estimates it from its VOC sensor. This is highly inaccurate and not recommended at all. This is why it's important to use an NDIR CO2 sensor that measures the CO2 molecules directly.
I've been using the Awaire Element. It works immediately with Home Assistant without special drivers. Seems pricey, but since it was used for a while in some crypto computing thing, tons of people have been selling them used on eBay for $99 or less. Sensors are commercial quality rather than consumer/basic level.
Awesome topic to cover! I’ve got air quality sensors all over my house too and it’s been a good quality of life upgrade.
Love your channel!
@@pabloescobar9337 thanks!
Please post a comment on what sensors you use.
@@jeffkirk4761 I’m using a few Qingping Air Monitor Lites into HA, as well as some Awair. I have a few Mila air filters that have great sensors built in too.
I got the Apollo Air-1 and now it’s automating a 500 CFM dust collector fan in a large maker space. It’s awesome. But, it cost over $100 all in with shipping. I got a bunch of the Sensirion SENS55 sensors and ESP32 boards but now I’m lost on how to get them working together. If anyone has any direction on that it would be completely awesome :-). Thanks for turning me on to this Reed!
What 500 cfm dust collector do you have and is it good?
I know its been only 3 months, but now my Airgradient Indoor arrived and I can't wait for your home automations with it :)
In a video about air quality, i don't see any plants in the house! Might be a solution to your problem thats a lot easier than running fans and automations.
Are you then supposed to open all the windows to bring in fresh air ?
In Germany: yes.
In the rest of the world, HVAC (optionally with heat exchange) is getting more and more common.
I adjust the speed of my HVAC to keep the air quality within acceptabel levels while not sucking out too much hot air in the winter (or cool air in the summer)
Ecobee doesn't measure CO2, it approximates it (you can look it up in their docs). And in my experience, it does this poorly. Get yourself an Apollo Air1. Huge miss that it wasn't even reviewed in this video as it's way better than any of the others mentioned.
Great video. A lot of useful sensors I also do not expect thay I needed.
Btw
In your intro, the solutions for your productive problem is add natural light in your room. decent amount of Sunlight during work room add more productivity and energy. That’s why Apple Park HQ want office to have the most natural light as possible. Hope this help.
What is the make/model of the little screen you use to display a dashboard at 00:12 of the video? Also amazing content!!
Reed, time to get some plants for your office. You can for sure cut down the number of events you have pretty easily and then you can review various watering and water monitoring sensors for us. Win win.
Reed, There are also several studies on plants being beneficial to mental health, productivity, and creativity. In short, I second this motion. 🪴
Reed, there's this guy on youtube that tested this theory that plants have any chance to offset your co2 production in a sealed room and the conclusion is that it's all bullshit because you need way more plants than would fit in any one room for any one person. But you could test this out with a sensor for sure.
The devices you mentioned measure for co2, but the drowsiness that kills your productivity is not caused by the high level of co2, it is the low level of o2. The human body converts oxigen to carbondioxide.
What light bulb do you have in the ikea sonos speaker lamp?
Its a LIFX bulb
(04:00) have you previously tested the Aqara Indoor Air Quality Monitor? or isn't that worth to look at?
Wow, I've never related so much to work life as at the beginning of this video. Looks like I need a CO2 sensor. Thanks Reed.
Another air quality metric to look out for, especially in colder climates, is the humidity. My apartment is very well ventilated meaning CO2 is not a big issue, but as the temperature outside drop below like 10C, the air can't hold as much humidity, leading to lower relative humidity inside. This can cause sore throats, headaches and increased risk of spreading airborne diseases such as a colds. Many smart thermometers comes with hygrometer, and if you see the humidity drop below 30% you probably need a humidifier.
aww man, cant believe you just got into those. i'm doing this for 3 years now. using awair (recomending it) air sensor which gives out local webservice with co2,voc, pm, hum, temp and using that to command my MVHR with modbus auto-magically. it is awesome, automatic boosts in ventilatiin if something goes to high quickly or just increasing the pace when needed.
An important and well-researched video, thank you @smarthomesolver. Inspired by your effort, I bought an Ecowitt WH46 air quality sensor and integrated it with my Hubitat network. I have already learned that I need to open the window more often in my work-from-home office, based on CO2 levels.
Interesting video. Would love to see a follow up video about air purifiers that have these sensors already built in AND are usable in Home Assistant (hopefully locally).
Especially with your recent does it work without the internet episode, do these require cloud do they talk locally to home assistant?
Great question and that was an awesome video! I cannot speak for the other sensors but our Apollo Automation devices are all fully supported in HA/Made For ESPHome, local and open-source. They do not require an internet connection or monthly subscription to work. Let us know if you have any questions!

The public health nerd in me is in love with this--thanks for sharing! Air quality is so important.
Does your home not come with an air exchanger? We have ours running on low and it constantly circulates out the old stale air with fresh air.
I have a HRV that's always running since its a new build so its built airtight. Or the windows are opened a tiny crack to get some fresh air and ventilation before i get cabin fever. Living in Vancouver is a plus since the climate is relatively mild. There's something about the fresh air hitting your face that feels better than circulated air from an HRV, AC, etc
Pretty cool, have you seen any that can detect natural gas? In my area we use natural gas for our house heating up in the attic. We also get a lot of lightning storms. There are always a couple of houses every year that get the unfortunately combo of a gas leak and lightning strike that makes their house catch fire. There are even more that just have a slow leak that fills the attic with gas requiring the fire department to rush out. Having something up there that could sense it and warn you would be really awesome.
@@LifeWithMatthew Yes, our Apollo AIR-1 uses the MiCS-4514 gas sensor to detect Methane which is one of the main components in natural gas.
Hi, any more options for a co meter? I would like to put one close to the fireplace. I love that all your options had home assistant and are mostly wired. Do you also have recommendations for fire alarms? maybe a system that work interconnected, if one goes off more of them go off?
Nice chart! I wish there were more options in terms of Radon sensors. It's very prevalent where I live in Oregon. Samsung has ERVs as well but I think it's either exclusive to other countries or just not advertised here.
An even more over-the-top and more expensive sensor is the 'air-Q pro'. I bought one, loved it, and bought 3 more. It works great and has native integration with Home Assistant.
You can see the output of those sensors in this shot from another Smart Home Solver's video: th-cam.com/video/EBT1mnLMPmI/w-d-xo.html
(The charts were created using the mini-graph-card)
The Air-Q Pro can detect:
- Oxygen - O2
- Carbon Dioxide - CO2
- Carbon Monoxide - CO
- Particulate Matter - PM1 + PM2.5 + PM10
- Nitrogen Dioxide - NO2
- Hydrogen Sulfide - H2S
- Ozone - O3
- VOC
- Temperature - T
- Relative Humidity - ρrel
- Air Pressure - p
- Noise - Lp (averages over 20 minutes)
Could you do only about the ring alarm system video and what new cameras are around your house? I love that so much!
You should look into getting a good air purifier in your bedroom and office especially with voc being an issue :)
I have been using the Milesight sensors myself... AM100 series has temp humidity and CO2, but the AM300 has also VOC, PM2.5, PM10 and O3 (plus pressure, light and has a small PIR on the front).
Only downsides are that they might be a bit more pricey, and they use LoRa so you need a LoRa gateway and get the data via MQTT.. but on a positive note, they all look much nicer than those to be fair 😊 look at the AM319 and the super nice paper display... Hard to beat
Great video, thanks!
Do anyone know if it's possible to turn off the inducator light of the Airlytix ES1?
Another super helpful video, thanks Reed!
@smarthomesolver , I have the govee air quality monitor and it’s linked to my govee air purifier, I have it set whenever pm2.5 reaches x amount it turns on high speed until the air quality is set to the range I set , I have 4 of these in my home one is in the dining room area so whenever I cook/fry it goes on the highest speed until the air quality is ok .
It is cheap. US$40 on the web page but it would be good to have CO2 as well. Are you using Home Assistant? Does it connect using Bluetooth or do you need Wi-Fi? TIA
My Govee doesn’t have co2 , it works over wi-fi through the Govee app and it doesn’t need a hub .
I have ERV ventilation at home and since many years I made an automation with HA: the level of CO2 are monitored in each room and thr level is kept constant
I like the e ink sensor but why not leave the fan on low? Does that not help? Not trying to be rude a serious question.
Power and noise probably
That toast!! 😮
Great Video!
I love the lamp in the back, where'd you buy it?
Dude I’ve been telling people this for years!! My friends and work colleagues just shrug it off and think I’m special. 😂 Then when I show them my Airthings data from BEFORE & AFTER my ERV install they know I’m
Telling the truth!! Also, I automated my ERV with one of those Aqara Relays and it worked perfectly! 😁
Which is more urgent for the home if I have to choose between CO and CO2?
CO is WAYYY more urgent if you don't have one. New homes are required to have multiple CO detectors, very similar to smoke detectors.
I just setup the IKEA sensor with Z2M and it shows VOC through MQTT. I'm guessing you used ZHA.
Learned from an unfortunate experience in a NYC hotel, bed bugs are attracted to CO2. By having a fan that pushes the CO2 away from your head and your bed, you are also removing the bed bugs ability to find you should you bring some home from a vacation. They would eventually just die assuming you have appropriate pest control.
Radon levels can go up if there is a leak/crack in the foundation of the house
It seems like the next logical step after monitoring air quality is to look at air filters. I know it's not necessarily smart home related, but there are cheap, DIY air filters called Corsi-Rosenthal boxes (a.k.a. CR boxes) that can outperform expensive HEPA filters. To make it fit the smart home channel a little bit more, you could put it on a smart switch to turn on when your monitor detects the air quality is too low.
My Dyson air purifier has taught me how bad the air can be, has the PM sensor etc. When you cook smoky stuff you can just see those numbers go through the roof. I was at a house the other day and they had some sort of whole house fresh air exchanger thing in the basement, that might be the way to go.
Thanks for the great video Reed. Another video that will end up having me spend money on the smart home . . . . which is inversely related to the magic in the bedroom 🤣
How much is AirGradiants cost after 1/2 years? You only get access to the data for so long then you have to pay?
Achim from AirGradient here.
We currently do not charge anybody. Wven after the free period or 1 or two years they have unlimited access. We might charge in future a very low amount for premium features but will always keep a comprehensive free tier.
We are also open source and it is easy to send our data to any other platforms like Home Assistant and not use our cloud at all. So you are not locked-in into our platform at all.
@@AirGradient Can I integrate Air Gradient into a Homey pro system?
No but want one that dector of mold and cigarette. I live in an apartment With people who smoke and it comes in through the windows. Also bad neighbor smells Any ideas?
Very useful and eye-opening!
How about detectors for carbon monoxide CO and propane leakage?
Nice video Reed! This is a more unique sensor type.
@smarthomesolver do you think there is a market for ice detection sensors?
Afaik a good co2 sensor requires relatively significant power, so a battery powered o2 sensor is likely approximating co2 values indirectly
Is it a good idea to keep a 3D printer outside?
I'm actually more interested in that small USB to USB square thingy that seems to connect the Appollo to a charger AND maintain it in place

Radon should be treated with ventilation if you have it
Agreed, and I don't think people should be ignorant of it in an area that has high radon levels. I'm from Iowa, and we're evidently one of the states with the highest radon levels. I invested in an Airthings Wave Plus so that I at least know what I'm being exposed to in the long term. It's not even crazy expensive for that model since it is bluetooth-only. That's not a downside to me since it means it can integrate locally with Home Assistant (no cloud dependencies).
Yep, for those who don't know, Radon is an invisible odourless gas which is produced when some rocks break down over time, so it depends on the geology under your house as to whether it's an issue for you. It's emitted from underground, and outside it just dissipates harmlessly into the air, but it can come through the floor-slab of buildings, and it's carcinogenic, so if high levels of radon build up inside your house (or office), occupants can develop lung cancer over time. I live in Ireland, where the geology of most of the country means it's an issue (two people a week die of radon-caused lung cancer in a population of 5 million). New houses have to have a radon barrier in the floor slab by law, but older houses like ours don't have one. Our original test readings, using the Airthings Radon sensor, were nearly 400 Bq per M3 (over 100 means you should take mitigation measures) so, during a remodel, we installed MHRV (Mechanic Heat-Recovery Ventilation) which changes the air every few hours, but uses a heat exchanger to recover the heat (or coolness) of the exiting air to heat (or cool) the fresh, incoming air. Our radon readings now range from 20-80 Bq/M3 (depending on the season, more radon is produced in wintertime). MHRV also keeps internally-produced CO2, VOC and PM levels low.
I'm an Anaesthetist in the UK (aka Anaesthesiologist). I am very skeptical about the CO2 claims that people Keep making. The CO2 level in your body is not regulated by your environment but by the pH of your cerebrospinal fluid, if the CO2 in your environment rises - you just breathe more, dropping your CO2.
The meta analysis that this claim seems to be originating from has some weird results, likely due to publication bias. It shows that congnition drops with 1500ppm but drops *less* with 3000ppm.
More likely that you lose concentration after working for a while, which is also when the CO2 is high because you've been in the room for a while
That being said CO2 may be a reasonable surrogate marker for the "freshness" of room air - with stale air containing more harmful components.
Thanks for your comment. Is it not true though that in a closed bedroom with two people sleeping the CO2 will rise and as you say require the occupants to breath more. If one of these people has sleep apnea or other breathing issues, a sensor that can detect the rise in CO2 and trigger some fresh air to be brought into the room would be beneficial.

I've been using Netatmo for some years now, it the indoor sensor have CO2 reading and I first thought it was a gimmic. It constantly showed above 1k ppm.
Turns out, it's sensitive to what you place it close to. I had hidden ours in a mocca plant, and.. that where apparently not so great for readings of CO2.
How’s the office sharing situation? Honeymoon worn off? 😂
Why not introduce dedicated air purifiers? Or, an air purifier attachment to your HVAC? Obviously these are useful but treatment would be nice as well
So this started a whole new cycle - I said we need more sensors, my wife said we need more plants - which means more sensors for plants.

I would say that the light should turn yellow when the CO2 level goes past 700/750ppm, and red after 1000ppm. Fun fact: Over 100 years ago, in the 1920s, it was recommended in England that infoor CO2 levels should be kept below 1000 ppm to ensure good air quality and health.
