Poor air quality can lead to many negative health effects as well as can cause tiredness, headaches, loss of concentration, increased heart rate and so on. Monitoring the quality of the air may actually be more important than you realize. So, in this tutorial we will learn how to build our own Air Quality Monitor which is capable of measuring PM2.5, CO2, VOC, Ozone, as well as temperature and humidity.

Why have you been SO inactive during the past couple months
You really should need to form a KIT COMPANY for STEM. Many kids and adults would benefit from a subscription where each of your wonderful kits would teach them much more than they could learn in schools. Your amazing skills should not go to waste. I'm surprised how much effort you put into these projects, you are great engineer, teacher, and person to provide these great ideas and videos. The biggest problem for individuals is sourcing small quantities and the waiting from each vendor on parts. A kit would allow people to quickly move forward to learn and enjoy. The only item would be the 3D printer, which many people who are interested in STEM already have.

Can one buy this fully assembled ?
hello brother can you tell me how about to use sleep mode LCD 2.8 inch TFT types SPI with arduino uno
please brother .
thank you your video bro
Hey man, just wanted to complement you on your thorough explanation of the function of each sensor, especially including brief info on sources of contaminants. You get a lot of info in without getting off track or droning on and on, and it makes for a great video.
Thanks for explaining how the sensors actually work 🙏
your channel is one of my best discoveries, thank you
Your tutorials are great and I appreciate that you provide the STL files. However for those of use that want to learn to design specifically mechanical parts and robots, it would be great to have a series that explains more of the designing process! Thanks for sharing your knowledge and creative projects!
wow! Great project and tutorial as always! thanks a lot!
Great Project. Thanks for explaining how the sensors actually work.
I like how he explains how the sensors work on a mechanical basis, not just how they're used electronically.
I should build one of these, for my oil painting area. At least the VOC part.
You can get a Sciosense APC1 evaluation kit for that, just plug it into your laptop and use the software they provide for that. The evaluation kit is different than the sensor by itself, the evaluation kit (EK) comes with the usb cable and software and it works perfectly for 1 sensor.
Fabulous build. Thanks for posting and for all the linked details. 💯👏
Great project, and integration with home would be great! Thanks for this project!
Glad you like it!
this build is so clean
This is awesome. I was going to make something similar a couple years ago but had trouble finding a decent ozone sensor and the VOC sensor I have is basically useless. I also want to add a GPS for portable use..
Excellent design and build. Thanks for sharing.
Thank you for ideas for really useful project. Happy new 2021!
Thanks, same to you!
A fantastic video. If you decide to carry on with this project a carbon monoxide sensor would be a great addition to help protect people who use gas for heating.
Ever thought about using an esp to integrate in smart home systems instead of the arduino? Would also have 3.3v diectly
Really nice and realtime project that can work as well as weather station, super 💙💙💙
Thanks! Well yeah, the possibilities with this project are endless. I mean, you can modify it however you want.
Brilliant, thanks for this.
Nice build!
very cool project, you have inspired me. We need a customizable portable VOC sensor at our company for our service techs, this would be a great option. Thanks!
nice content as usual, thanks!!
pls the code explanation part is not boring at all, in fact is the most relevant part of a project, kindly do not be skipping it!!!
most of the times i have got to learn new programming concepts trough your code explanation.
I will keep that in mind, thanks!
@@HowToMechatronicscan this instrument record and save the data?
Congratulations on 500k subscribers!
Thanks!
awesome project as always!
Thank you! Cheers!
Great Project - Got everything on order! Can't wait to build! Can you point us to a complete bill of materials for the passive PBC components?
For the rebuilder:
Correct resistors values: R1 = 1K, R2 = 2K, R6=100K or 1M, R7=1K
have fun , Mike DF7MR
High-quality content, congratulations!
Thanks!
But low quality air! CO2 that high means you need more ventilation in your bedroom.
Hi,
Another great project, perfectly implemented
Greetings Wolfgang from Germany
Hey, glad to hear it, thanks!
Excellent device and content in general. Thank you.
Thank you!
Really awesome video ! Thank you so much, this is great stuff !
Glad you liked it!
Super cool! Has me considering a touchscreen and custom PCB as well. Only thing I would change is to network the device and log the measurements somewhere that Home Assistant can integrate.
Yeah, that would be better!
What would be the best way to do that? I’m trying to integrate this into my HomeKit using homebridge.
Through an esp8226 potentially
I was just wondering, why not use BME280 for temperature and humidity measurements? It has much higher resolution and accuracy than the DHT22. Air pressure reading is a bonus.
Beyond wonderful ♥♥♥
Most excellent work 👍🙂
Very good educational video! Thank you!
Don't get me wrong, the thing is very well made, and I understand that not everyone is comfortable around ESP8266, but this project seems to be a perfect fit for one of those.
- No need for RTC (just get time from internet (at power up) )
- Upload new sketch over the air.
- Check your graphs and data on any android phone (can even skip the display.. which is expensive)
You are absolutely right! Thanks for the input!
RTC is always needed as backup in case when your internet connection is down
@@acerrusm You can always display the current values from all your sensors
You can also always collect values based on relative time (every x minutes), display those and sync the time axis with the internet time when it becomes available.
The internet in my place is seldom down, and never for more than an hour.
@@acerrusm not really, if not real time-sensitive, in my experience internet down does not happen much, maybe different in your country.
My greatest compliments for your design. I build it and it works perfectly. Very good thinking about features and timeline. I made some adjustments so I can easely exchange sensors, but for now I cannot imaging what I should change. Calibration is for me less important compared to more or less value readings. Maybe the loss of data when disconnecting the power could be a minor issue to solve. Thanks for all your time! Great job!
Hello! I'm a student and I need to build this for my studies. Could you please provide the materials you used and where did you order it, if you don't mind? It will help me a lot. Thank you!
Great video! As a environmental eng, I can tell you thats amazing. Low cost and very good precision. Did you comparate with a real sensor, like a industry sensor?
Awesome video!
Nice project
That's a cool idea
Such a good tutorial, thanks
Glad you enjoyed it!
Amazing project!!!
Thank you!
Nice work!
Very good and very informative video. The next upgrade to this project should be an air purifier. The air quality will send feedback to the fan when the desired value is achieved, the fan will automatically stop.
Thanks for sharing your knowledge!
My pleasure!
Awesome explanation as always. Out of curiosity, did you consider using BME680 sensor from Bosch during the design phase? Because it does the work of PM503 and DHT22 combined, plus it even has some kind of pressure sensing, which affects whether pollution levels build up.
Amazing as always :D
Thank you! Cheers!
Nice video clip, keep it up, thank you :)
have you thought of adding an NO2 sensor, as you are already monitoring O3 you can correct for the crosstalk of o3 with no2 in the no2 sensors. no2 being one of the main air quality pollutants causing problems.
Great video and very informative!
Glad it was helpful!
we are waiting for your next project
Great video!
Very nice project, thanks.
May be a better sensor for temperature and humidity, the DHT22 is not very accurate.
Thanks for all the great information! Do you have any recommendations for a company that 3D prints cases? I'd like to do something similar but hide the inner workings.
Woow Good job ❤😍
That's awesome. Acrylic is 200 dollars a sheet where I live in Canada
Excellent video and project
Thank you! Cheers!
Excellent vid. Happy holidays. 💙💚💛🧡😎
Thanks, same to you!
Nice video and always nice project
Thanks 👍
Fantastic work 👌👌👌
Thank you! Cheers!
Excellent project for the right person.
I built one 3 years ago. No LCD, since I used a ESP8266 module instead of a promini, and did everything through the browser.
I only installed DHT-11, MQ-5, MQ-3, MQ-9 and MQ135, VEML6075 UV sensor, and DSM501A PM2.5 dist sensor, which was $4!
I think my project cost about $25-$30
Yours is in excess of $100 without a PCB.
Yeah, that's true, the sensors I used are not the cheapest, but of course are more accurate and reliable.
Hey there
Would you like to share details please
great video!
Great video, I would like a fan going over the sensors separate from the 2.5um sensor thing though.
Well yeah, maybe that would be a good idea.
Beautiful
Great video, I made a similar system based on ESp32 without display but It can be integrated in home Assistant so you can check data also remotely
Hwy there
Would you like to share details please?
Hello,
Did you manage to compare the acquired data with a calibrated source or calibrated sensors? I am mainly interested in the PM2.5 sensor.
Regards!
Exactly
This is excellent, may use this for my reptile enclosures! I get paranoid they aren't getting good enough air quality.
Just let your kids play outside once in a while :D
Wow! This is great! If it also included Radon and Carbon Monoxide I would definitely buy one. Do you sell these?
Amazing Video Love it!
Glad you enjoyed it!
Отличное видео, спасибо за гайд друг!
Yes another top quality project worth the wait :)
Thanks!
THANKS
Thank you.
Good project. Now add CO, HCOC, PM10 and it will be one of best air quality meters!
Actually for the PM10 @2:27 the sensor can already switch between them and the upgraded version can do somewhat better (PMS7003) what are the others polluants are you talking about? HCHO? sry not really my field. I'm interested in making one of these air monitor based on that one.
@@hugodc1225 Oh so PM1 and PM10 are included? That's great! I missed that one, sorry:)
Well HCHO (hcoc was a typo) (although the real formula always used to be CH2O ... dk why manufacturers have changed it to HCHO) is Formaldehyde - one of biggest indoors pollutants nowadays to worry about.
And CO (unlike CO2) is Carbon Monoxide - an infamous "silent killer"! The stuff is lethal. There could be a fire in neighbor's flat and CO can kill you even before your smoke detector/alarm triggered.
Although of course it is worth to have CO detector alone (next to Smoke detector) in few places of your home.
This is a great video. Is the circuit board available through you. I tried going to the site that makes the boards but there were many questions I did not understand. Thanks
Very well presented.
How do you make animated sketches such as how the PM2.5 sensor is working (2:07)? Which software:)?
Thanks for sharing, this video is gold.
Great project
Thanks!
Excellent choice of project! Why? People have been spending much more time indoors during this year of the COVID-19 Pandemic. Providing a completed working system and not just a prototype was wise. Because this project is important to the world's population right now, I would suggest: Phase 1, 2, 3, etc ... future upgrades of this project that would verify accuracy or readings, allow internetworking of nodes and of course IoT. Thank You Sir!
Excellent project, soon to appear on Wish for $21.99 delivered next month!
It's one month later now. Hmu with a link my g😂
I love the code
Hi Dejan thanks for the amazing project
I was just asking about the Mq131 sensor, its mentioned in the datasheet that it should be preheated for 48 hours
It is also mentioned for Mq7 sensor that i want to use ? can u guide me throgh this?
Can i use the sensor straight away after purchasing or should i do the preheat procedure ? and how can i do that ?
your a genius
A fantastic project. I want to do a PM2.5 indoor air project, and this gave me ideas to add extra sensors. I'll be using an ESP8266, as I want connectivity to my Home Assistant home automation. I'll send MQTT messages to send the air quality data to the home automation system. It'll be a while though, I've got a couple projects in front of this one.
I also have the same idea, may i ask how do u power the esp8266? I want to power by batteru but don't know how to do it
@@ThanhNguyen-zi8sd I was just going to use a USB wall charger to power it, with the 5 volts it outputs. I haven't ever used a battery to power one.
@@astrostevehobby5096Thank you, I also want to ask that my sensors and LCD use 5V so can i connect all of them to the VU pin?
@@ThanhNguyen-zi8sd All the boards are labeled a bit different. But as long as the sensors don't take too much current, you can power them from the 5v pin. You might want to Google "Feeding power to Arduino: the ultimate guide" and read about how to feed the boards power (even batteries). For my larger projects where the parts I hook to it take more power than the Arduino can supply, I use a regulated 5v power supply, and input power to the 5v pin (not recommended, if you read the article I mentioned), and I can power the sensors not from the Arduino itself, but from the power supply, which can provide more power. In that case, just don't let the power run thru the Arduino first, the traces can only have so much power running thru them. I'd assume most projects and sensors would not be a problem. You'd have to Google how much power your particular board can supply. For the ESP8266 type boards - I have not used one of those yet, and an unfamiliar with them, except that it can be supplied with power from a USB charger.
Hey there
Would you like to share details please
Hey. Its good to see your work and effort as it motivates us.
I want you to tought us about the a drone of our own.Can you make a video on drone project
owesome!
super awesome
what software do you use to make the layout as shown?
Minute 5:20
Nice quality and explanations. Respect for the handwork, I mostly use a laser for it 😎 Greets from a medical engineer.
Thank you! Well I do plan to make a CNC machine so I don't have to make things like those by hand. Cheers! 😀
@@HowToMechatronics that's a good idea! Do you share your build process here?
Great Project. do you know what will it take to use a NodeMCU instead of the Arduino? I want the same setup but that will also connect to Home Assistant via WiFi
Did you ever find out how to integrate it into Home Assistant?
Hi, very nice project. Do you have similar project based on ESP32? Would be nice to have integration with smart home and reporting via Mosquitto.
Hey which software do you use to make the art in which you explain the sensor like on 3:34
Awesome
Congratulations for this project, I wonder if this detects dangerous gases as hydrochorich acid fumes or others, I'll appreciate your answer
Bravo 👏👏👏 . One question though 😋 i would like to send data to an api endpoint like grafana to keep track of the registered data. Any idea if this is possible?
What are you using to measure the air and where can I download the cad software your using?
Miss you buddy
I was eagerly waiting for your videos bcoz your video ideas are very unique and very informative. But you post once or twice a month.
It would so nice we you could do atleast do videos a month.
Trust me, I do my best. Making videos like you named them "very unique and very informative" is very time consuming.
I really appreciate your time and efforts 😍
I would if it needs to calibrate for knowing its accuracy,tolerance, error etc.
A very nice project that I was very much interested in for VOC monitoring until I realized that you can actually buy an air quality monitor that covers VOC's for less than just the PM2.5 sensor in this project costs
what is the estimeted price for this device ?
