Building My Perfect Smart Home Presence Detection Sensor!
ฝัง
- เผยแพร่เมื่อ 28 มิ.ย. 2022
- A few weeks ago, I took you through a custom built room presence sensor which used mmWave to accurately detect the presence of a person in a room - even when there was no movement. The DIY sensor we built is amazing for controlling things like smart lights in rooms when you don't tend to move around much, like your living room or bedroom. So after that video, I became focussed on how to improve this sensor and what other sensors I could add in here to make MY ideal room presence sensor, everything from light levels, temperature, humidity and of course, multiple levels of occupancy and presence.

Would love to buy a few of these without having to buy the components and assemble, but appreciate that this is such a great solution.
Well you never know...
Would be much easier to use a breadboard and jumpers than soldering. It may seem daunting but it gets pretty fun (and maybe a little addicting) after a few attempts.
oh geez me to! Id buy 4/5 right away! these things are great and i font have the time for building them.
@@EverythingSmartHome could these sensors work with hubitat too?
I would 100% buy a bunch of these!
This is so awesome! Presence detection has always been a pain point but this seems to be the perfect solution. Cant wait for more commercially made projects to be readily available with MMW
Haha thanks, I agree!!
The fp1 is amazing. I spent months/years trying different combos of door contacts and motion detectors to detect presence in the bathroom and when in the shower, but nothing short of pressing a button to set my system into "shower mode" worked well. That all changed as soon as I received the fp1. Not only does it perfectly detect someone being in the bathroom, it detects through the shower curtain, and it even detected me in the shower when I accidentally put my clothes directly in front of the device.
I was able to remove all other devices and complex node-red flows minus one aqara motion detector to more quickly trigger the lights to turn on as it takes a few seconds longer for the fp1 to determine that there is an actual person in the room, where as a normal motion detector is nearly instant. I then only have to use the fp1's "off" mode when presence is no longer detected to turn the light off. There is no trouble in between anymore of lights going off when using the toilet or in the shower.
Great video! I loved that you built your own sensor that does everything you need. Makes me want to build one for each room in my house.
Thanks Steve, appreciate that!
This is awesome! Would be great to have some sort of documentation for this. So a buylist together with the step by step manual to put this together. Same for the STL file of printing a case. Maybe an idea when a V2 will be released? XD can't wait! Great idea!
I came back to this video for just half of this and I would be happy if that is all I found.
The parts list in the description is decent but not very detailed, once the links die it will be harder to find later.
The lack of STL files and the updated code mentioned in the video is the worst part though... I wanted to make 5 of these but make some tweaks and the lack of code really hurts. I am pretty disappointed as it seems this project is already been abandoned by Everything Smart Home.
Well, this comment didn't age well 😜 This project is very much alive as you can see :)
I will make a DIY version available at some point - truth be told this video was never intended to be a "guide" on how to do it, I more wanted to show it off - but lots have asked for one so I will chuck some stuff up at some point, I am currently very busy making this a full fledged product for people to buy, but once that's done then I will try to make a DIY guide for those who prefer that route - I don't know how long that will be though, so meantime if you have any questions at all about how to make this, Discord is the best place - there is tons of information and discussion about this sensor there and more than happy to help
@@EverythingSmartHome thanks for the great response! Awesome this project is still alive and kickin!
@@EverythingSmartHome really hope you can have a version with air quality sensor. Congrats BTW
I don't think it is so awesome - incorporating few sensors as one and using lot of mcu interfaces is overkill. Probably better idea to use radar presence detector sensors like LD2410
Had this idea of combining sensor together per room since a while. The mm wave is a game changer. Thanks for the inspiration.
Thanks for watching!
Dying for a build and programming guide on this! You're the best
Other than the fact that I might have to actually get better at soldering, this video and its predecessor are right up my alley. Well, at least it's where I want to be but need to put in some effort first. Thanks so much for this. Once again Kudos to you sir!
Knocking the ball out of the park with this one! Added to my project list.
Thanks for listening to my suggestion: This will be the most interesting upload you have done so far since this is such an important feature most smart homes lack.
Thanks, glad you liked it!
Another great video thanks - this is one I must build
You should totally design a PCB for this! I’d love to make one, but I’m not great at PCB design. I’d hate to get started just to realize I have to restart due to a bad design.
Yeah, pcbway had to be cringing at the use of a proto board in a vid they sponsored.
I love it .. the mmwave is pure gold for presence, and getting the other sensors in there as well, really starts to make this a perfect smart home sensor solution
Thanks dude, appreciate it!
I would absolutely love to see a zigbee version of this! I have a bunch of ESP32-CAM cameras already, and they're a bit unreliable with regards to connectivity. The zigbee devices I have seem to be much more consistent. Also, I love the lower power draw.
If there was a zigbee version of this, I'd probably order a bunch.
Outstanding video, wow! So many ideas. Thanks!!
Awesome! I really like your DIY videos! Thanks!
excellent work! many thanks!
Great sensor. I can see having these all over my house. Well done.
Great video. Do you have a diagram showing all of the connections you made from each component ?
Excellent. Well done.
Excellent video - nice work!
9:00 by the way since you were speculating on this you are correct a 60ghz mmwave sensor is far more sensitive even being capable of detecting heartbeats and breathing which is why its so much more reliable than the 24ghz one when detecting sleeping humans, although it does this at a much lower range than a 24ghz module. To be fair the dfrobot sensor does specifically say in the instructions and even shows pictures to install the sensor directly above or under the bed when using it for that purpose. Seeed studio actually has a 60hz module for sale on amazon currently if you want to read about it maybe even test it. ............... seeed studio mr60fda1 60ghz mmwave sensor
Thanks!
Can I ask - because I don't see it - what the benefit is of being able to detect motion from a sleeping person?
@@JohnVanderbeck presence detection in a room after the occupant has gone motionless in bed
@@ezradmello7021 Yeah I get that but for what purpose? Just curious. Usually you use these for turning on lights but you don't want lights on when you are sleeping.
It's actually the opposite.
You'd use this as a bed occupancy sensor so you can tell when you're in bed or sleeping.
Ex: Slowly dim and turn off the lights if it's night time and presence is detected at the bed.
awesome work, Lewis.
You're a fricking legend man, can't wait to try this.
Enjoying all the videos related to this DIY sensor. That's a great prototype case. Are the STL available? I can see it useful to prototype many different combinations.
Pretty cool idea and looks to be a fantastic solution, certainly will be on my upcoming build list.
🙏🏻🙌🏻
This is an awesome build. Thanks for sharing 👍
Super sensor! Thanks for video! I'm going to try setup: light sensor, SCD41 (CO2, temp, humidity) and mmWave Radar
Pet friendly PIR sensor and KNX integration board.. great stuff
This is brilliant, thank you. I know it's kinda outside the spec of this, but I'd love a battery version for the bathroom.
This is what I needed thanks !
🙏
This is absolutely fantastic! I'm going to give building one a go. I was looking to do room temperature sensors, and maybe figure out room presence, but WOW this does it all, plus light level. Air quality could be useful, but like you said to add that would greatly increase the bulk of the design, at least right now.
Would you be selling the finished product?
For air quality, a CO2 sensor may be more useful than a PM sensor, and not at all bulky, but a sensor "good enough" is not the cheapest sensor.
brilliant project. So I ordered 5 parts right away. I hope there will soon be an explanation of how to put the things into operation.
Nice build ! Might also add a perfect presence detection sensor to my ToDo list. I agree that even if the price is pretty much the same, functionnalities are way better.
Thanks for the inspiration and keep up the good work !
Thanks, good luck with the To-do list 😅
Also if something goes wrong its easy to replace a part
Thanks for this video its inspired me to make one.
Great video and work!! For me I would love to have an all in one solution. Your sensor paired with humidity, air quality, co2 and smoke sensor (with optional pinhole camera, where you can use the mic for Siri or Alexa). All working via a LAN cable (power and data) and all in a ceiling mounted Smoke Sensor enclosure. Of course HomeKit compatible 😀. No Switches no nothing just one sensor on the ceiling and some in wall speakers and underfloor heating
Really great project. I've been contemplating this.
Thanks, be interested to hear your results!
RF Engineer here, seems like a fun project to put into one PCB. Thanks for sharing.
Thanks, that was the whole idea! Appreciate it!
You swine!! Just after I completed the first version using the mmWave sensor, you come out with this! Seriously, a great video and another fantastic project. I will be attempting this upgrade as soon as I can.
Haha apologies! At least you have the most important part already that is gold dust 😂
@@EverythingSmartHome Just snagged another mmwave sensor. When it comes, I'll have all the parts to build this multi-sensor. All I need is the schematic and the code to make it work!!! I can't figure it out from the video alone. Any chance you might make this available soon? Many thanks.
Air quality is something nice to add. Apart from your suggestion to add a particle sensor I would add a CO2 sensor like the SCD30. That will tell you when you have to ventilate the room.
Forgot to compliment you on this nice video…
This was essentially going to be my reply...swap out the bme280 for an scd41, and add co2 to the measurements I believe?
For rapid prototyping and permanent projects I got a fan of the wire wrapping and the glue gun. in comparison with a breadboard or a prototype board you can get quite quick a breakout board aggregate, works with most pin spacing and the glue gun fixes the wires on the pins and the position of the boards. Also most time no solder fumes :)
Bardzo dobra robota!
These are awesome and I would happily buy a few of these! Very Nice!
Thanks....soon!!
@@EverythingSmartHome ok understood, that's the reason why you don't react on questions like "Can we find the written article?" or "Could you please post the code?". It would be good if you openly communicate this (e.g. in your video description).
Up to now I found your videos motivating and inspiring for DIY projects. But finally it's all about making money ;).
Awesome work! So when can we expect a Kickstarter project for this bad boy? 😀
very good video, as always 😎👍
Great work, 👏 would be nice to see some content around how to setup automation between temp sensors and AC temperature control - keen to understand what would be the best approach to build such relationship considering energy efficiency for the AC
AC isn't something I have in this country unfortunately but shouldn't be too difficult...in theory!
Really nice work! I’ve been looking for a good presence solution for a while now and I was thinking about building an air quality sensor. Now I want to build both in the same device… and both are far beyond my skill level, but now I’m going to try anyway.
Good luck!
Another awesome project Lewis, well done! 👏🏻
Apparently the IKEA Vindriktning air quality sensor is reliable and can be hacked to connect to the ESP boards.
If you don't mind the noise from the fan. Audible in a quiet room.
Thanks Rob, that's good to know! I think the added bulk would be too much but maybe there is a way!
love this!
Awesome 👌
Great appetizer! Now what would be great is to have a project page with step by step guidance and code.
Will you write this up as a guide for others to make their own? This is just what I've been looking for!
yes please
Yes please
Yes please
Yes please
Brilliant!
Thanks! I’m looking forward to build a couple of these for my home. Do you have any idea of the power consumption of a single unit? Can it be realistically powered off replaceable or rechargeable batteries?
really enjoyed this, wonder if you could tie it up with being a sensor for a smart home intruder alarm
You are a genius 👏 this is amazing!
No genius but I appreciated the support and kind words 🙏🏻
Great Video. I love this. I was just thinking of making something like this but I am just getting started on my automation journey. Do you have the plans for the wiring and the code somewhere we can check out and learn from.
Please start calling it I square c, furthermore amazing video!
Would be great if you do a ceiling mount version of this.
Verrrry nice! Good work!
I‘d seen a link to your website with the words „written article“… but i can‘t find anything on the website…?
A wiring diagram and a .bin file for the ESP would make it very easy to make one.
I couldn’t help making a connection drawing if you want.
This is a pretty cool all in one sensor. I've been following crlogic's work over on HA too.
I do have a few questions/challenges for you though:
Why did you spend more money on STEMA/QT compatible sensors, proceed to solder them to a proto board, and them talk about the overall footprint being too big? In an effort to appeal to a larger audience, a fair number of the Pimoroni and Adafruit sensors are much larger than some of the more basic offerings, but offer more functionality (generally have a voltage regulator and level shifter to accept both 3.3V or 5V inputs, and have STEMA/QT connectors for no-solder connection options.) For example, a generic BME280 is 11x14mm vs 19x19 for the Pimoroni, and a generic BH1750 is 18.5x14mm vs 26x18mm for the Adafruit (~50% difference!). You do have to watch out for counterfeit sensors on some of the cheaper versions though.
For a prototype board, why didn't you use headers for attaching the sensors to the board? You definitely had the room to do it for this iteration, and it would have allowed you to swap out sensors during testing and future iterations if need be.
The BME280 sensor is very precise on its own, but most of the circuit implementations suffer from heatsoak that skew the temps at least 2* higher than actual. Putting the chip in sleep mode between readings, and adjusting the heater circuity can help, but mounting it directly above an inverted ESP32 chip is not going to do anything for accuracy.
Excellent. Seems like you should start commercial production!
Yes I would like to have such sensor in my house. The only thing I'm questioning is how it would cope with pets (e.g. a cat). Is this something you would handle by software or could it be done differently? Great video, thanks!
Incredible
Very impressive work, your skillz are to be admired. Please enlighten us on how we can build or optionally purchase this fabulous device
Great vid! I’m keen to know more about your decisions on espresence vs straight esphome for Bluetooth detection. Was it just the limited range of sensors for espresence? And what does Esphome give you that espresence doesn’t? I’m a few days away from placing a parts order to do espresence so keen to know if I shouldn’t!
if you are into sensors, look at the mysensors project. it integrates well with HA. I have battery powered temp/hum/lux/pir all over my house. works great.
wow this is definitely the all in one we all been looking for you are a genius. please could you do a full build and programming video on this one.
Thanks - I'll see what I can do
@@EverythingSmartHome I guess you not done with it yet you seem like you will add 10 extra features on the next one you build for another room at yours. So would be great if we can see detailed build. Thank you. Ps have not spotted in your videos what you do for living but you should be paid big big money for making these. Make your own brand 💰💰
Very nice build! I ended up using the energy meter that measures solar generation as a proxy for daylight levels. That avoids the light sensor picking up the brightness of the room lighting.
Thats a good idea too!
Lewis amazing video! Would love a v3 and a full build guide!
Thanks Mark!
Yeah a full build would def. be appreciated. Any plans for that? :) especially the code is needed as I haven't had the chance to play around with esp home and that new Sensors so far.
Really cool! I'll probably wait to do something like this until thread is on esphome on the esp32-h2; the ZigBee functionally is pretty significant to me with an already-fun amount of devices on my wifi network.
Love these sensor videos! Would love to see more. I havent yet seen anyone do a good TOF sensor video yet...hint hint 😉
Great video👍. As a tinkerer I'm would love to make a few of these rather than buy. Any chance of linking a circuit diagram in the description?
And your pilot newsletter was 👍 thanks for that! I added a few automation from it.
Just a thought the base, you could 3d print a plug mount so you can get the thing off the worktops like you can get for the Echo Dot.
This is amazing! Are you going to be uploading a full guided on how to build it to your website by any chance?
This is fantastic. I’m considering making something like this, though I might go for a pi pico w (support for it is being added to esphome) since I’m more familiar with it. Though the pi pico w does not currently support the Bluetooth aspect.
Do you have your ESP firmware available to share? This is a great product, I want to test this setup and then I plan on making a nice compact custom PCB.
Cheers for the video!
Any chance Lewis? :D
Excellent video! I’ve had bad luck with the PIRs I’ve purchased. The link in your video should get me a decent PIR. Using a HiLink HLK-LD2410C-p for microwave sensor. BME280 for temp and humidity. Then VCNL 4010 proximity, light sensor. Replacing all my esp8266 project with ESP32’s. Some with Pi Pico’s, using Micropython.
I'd be interested to hear if you've used them both in a corner of a larger room. I have the DIY one setup in the far corner of our living room and even though the FOV and distance should be well within its range it does quite often fail to detect consistently. In your example of waving a hand in front of it, mine works fine too. Perhaps it's more suited to the office desk than a larger living room. Hopefully I'll pick up a FP1 when they drop to around the £30 mark!
Outstanding! What about long term powering by battery?
I've been playing with one of those mmwave sensors for a while but haven't had time to make it usable. Looks like you've done all the heavy lifting, ordered the extra components thanks for your work!
Enjoy!
@@EverythingSmartHome So is the written article anywhere ? I'd love to take a look at the code
@@ulrar me too! would be great if I can see the actual code and setup
Hey, do you have a written article on this project? I couldn't locate it on your website. Thank you. Your videos and tuts are much appreciated!
Thank you for this very helpful video! I've not tried this setup yet but on many occasions struggle to solder properly due to the solders I have had or tried, would be helpful if you have a link to the one you use or one similar to get. Thanks
Very cool project. I wonder if a similar project would work with battery only?
Inclusion of lux sensor is great, i have some zwave/zigbee pir sensors with lux and this value is slow to change, so i use this value as condition in automation only for one light.
Would be great to include some battery, so it can work even when power goes out - to be able to use it as part of alarm system (alarmo) when i'm not at home.
Great video! I think I'll make one of this but without the temperature sensor. BTW, I would love to have these sensors all over my house, how so you solve the fact that it needs to be plugged? (mainly toilet with no sockets and corridors are my problem)
Thanks for the informative well explained video!
I have the same experience like @mortensentim511 with the BME280 - hum% 15-25% too low and temperature about 4°C too high. Also putting apart from heat sources like the ESP and after conditioning. Maybe the special soldering process was not maintained, it was on such break-out board delivered.
Alternative #1 I tried was a SHT31. Provides much more accurate hum% and temp values.
Alternative #2 which works even better for my needs: BME680. Very accurate, plus it adds a nice extra of VOC measurement. Fully integrated in ESPHome! Recommendation - use the bme680_bsec library, not the standard one. You will enjoy the much better AQI and other calibration routines in the background and calibration status etc. Plus you get a "CO2 equivalent", which is not too far off from a real CO2 sensor, side-by-side compared. For my purpose, sitting in home office for hours and needing a kick in the pants when to open the window it is the perfect match :)
BTW, particulate matter is interesting, but it will tell you that actually opening the window will *increase* the particle concentration, and it will get better when the window is closed. This is more for a kitchen or workshop I believe.
We wan't this in EU stock! such a nice idea and product
Thank you for sharing this project with us. As always, great video.
Would you mind sharing the codes with us?
Yes! It's been weeks I 'm thinking that using an ESP should be for multiple purposes. I thought of many possibilities but the idea to put all sensors around one D1 mini is excellent. Maybe I would add a microphone.
Can't do much with mics in ESPHome, yet. No i2s input support (yet). They did just add i2s output, though, so maybe not too far away?
I'd love to see this more compact, in a unit like the Aeotec multi-sensor. I wonder how difficult it would be to reverse engineer those boards and create a single PCB with every component neatly installed together. I also wonder if there is redundancy across the boards, as I assume they'd have circuits performing similar functions and therefore using similar components repeatedly.
Nice, I've been toying about with trying to do this since your last video, I've still got all the amazon links open from the kitchen lighting that I also want (need!) to do.
Thanks for sharing. Be interested to know if it's possible to get it in an even smaller form factor (in a DIY sense)
That's the one thing I would like to do also!
Amazing DYI , big respect, i am wondering if the presence sensor it is able to work in a ceiling fan zone, because the aqara fp1 get false occupancy state when you turn on a fan in room
Thank you
Man.. what a great video. First off all, sorry about my english. I'm from Brazil and my english suck.
Your last diy mmware presence sensor video have inspired me to do one of my own. I have used a Microwave sensor called RCWL-0516. Was the cheepest that i found. It's too expense to buy these mmware like yours here in Brazil. Have you heard about these RCWL-0516? Works ok with ESP Home, just a binary sensor. Better that PIR alike sensors at least. Give it a try! Anyways, thanks for the content!!!
My god man! Clean your tip and maybe watch some soldering videos!
I mean that, but awesome job on the module. I want this for sure. Simply great.
Love the video. Your soldering skills need some love though...
Wow! That's just great! It is really hard to imagine more functionality than you just added. Rather expensive, but every cent you spent has its reason explained. Congrats. I will definitely assemble one of this (and probably a cheaper version to compare if it fits my needs). A question here: have you thought of ways to compare human presence vs pet presence? There are some automations I would not like to have my 40 Kg golden retriever triggering...
BTW, I know bluetooth can differentiate pets, but I'm usually not carrying devices at home...
A lot of the industrial HVAC occupancy sensors use CO2. Because people breath roughly the same amount you can judge the amount of people based on the curve of CO2. It's also a fresh air thing. Cool project man. Keep up the good work
Brilliant! I really need to dig out my soldering iron, currently using Hubitat with Hue motion sensors and they do the job. But, at some point when I'm time rich, I'll be moving onto Home Assistant (assuming I can purchase the hardware, global chip shortage and all).
Thanks, look forward to seeing what you make!
i am inspired. Looking at this, I realise i still have a lot to learn. But I'm going to try to replicate this. i hope some more info comes out on how to put all these sensor together in esphome code.
But for now Google is my Friend ;-) and thank you for sharing this
Amazing project Lewis! Start selling them! :D
