I Built My Own Presence Detection Sensor!

- เผยแพร่เมื่อ 30 พ.ค. 2022
- After taking a look at the Aqara FP1 Sensor a few weeks back, noticing it's lack of availability and price tag, I decided tried to build my own presence detection sensor with a much tighter budget. Both of these are mmWave sensors used for Human Presence Detection in rooms where there is no motion and can detect the smallest amount of movement. In this video, I show you what I used, how I installed it and how to integrate it with ESPHome and Home Assistant in your Smart Home. Finally we look at how well it compares to the Aqara FP1?

How crazy is that detection sensitivity!? 🤯
Is so mind blowing that i am going to make one without having a particular purpose yet 🤣 . Coud you share the 3d model did you make?
It works perfectly.. it’s crazy man .. I have make 1 asap
Its wild, you just stick one finger in and the sensor goes weeeeeeeeee
There is a hidden sensitivity setting.. ..coming soon ;)
@@andybgrant33 don’t tease…
Love this content. It's great that you cover things that is a little more advanced than some of your peers. Keep up the good work!
This looks like a great way to make my occupancy automations much simpler and hopefully more reliable. Just ordered a couple to check them out! Thanks for the well made tutorial :)
This is fantastic. Just got a soldering Iron for my b-day and this sensor just got put on my todo list. Thanks for all you do Lewis!
I love the way the community can come together and make cheap sensors to solve so many problems.
Could directional movement be written into the Arduino Sketch, based on the time it takes from when a wave is sent out and it is detected by the sensor?
A great video Lewis. Been using Digiblur's multisensor for a couple of years and will now be adding this senosr to my package.
Very interested in everything ESPHome and also your videos on presence detection so absolutely loving this content! Thank you for all the work that goes into making these videos!
Appreciate it, cheers!
probably my favorite video you've done. thanks for this great info!
Good find and research, looking forward to giving this a try when I switch back from woodworking mode to electronics tinkering mode again in a few weeks. Thanks for sharing!
Thanks for commenting, appreciate it!
What's the criteria for switching?
This is an amazing guide. Thank you so much for putting it together. I'm following your video to build one as well.
Best Tech channel! Regards from Brasil 🇧🇷
This is awesome! I am going to build a couple of these in the coming months. I think I am going to put these in my living room, workshop, office and bedrooms.
Thanks for making this video and sharing.
Thanks, have fun with it!
Another amazing video!!! I did your bed presence sensor… and definitely my best sensor!! Only difference im running it on esphome…. Cant wait to build this!!!!
That's amazing, thanks for the feedback! It's my favourite sensor too!
Love to see smarthome DIY like this. Thank you for sharing.
Thanks, glad you enjoyed it!
This is absolutely incredible!! Great work as usual!!
Appreciate it
Thanks for another wonderful project. Nice having a project that uses esp, always fun.
Thanks Claire! Agreed, they are super fun and versatile!
That's amazingly impressive for a home-brew project Lewis, well done!
I'm getting more and more tempted to get my soldering iron out and try some of your projects 🙂
Doooooo it 😅
@@EverythingSmartHome ok, ok!
@@EverythingSmartHome I mean, what's the worst that could happen...
You can combine this with a few things like auto lights, water or even telegram messages
@@rob1971 in fact, now that i remember, i wrote an article about how to do this using any camera and report back to you in your telegram
Wow this is so cool! Nice work! I’m going to have to try this if I can finally make myself try to learn how to solder lol.
My man... Consistently coming through with the best developer/builder HA content
Ah very kind, thanks so much! 🙏
Wow this is awesome, very tempted to try this!
Thank you Lewis, followed your instructions and used your code and it just worked.
Was actually just reading in to this today so your video is very welcome!
Nice one!
If I had to wager a guess, I think that the faster detection speed but reduce feature set compared to the Aqara go hand in hand. The Aqara must be doing some sort of processing to determine the movement direction, etc, which would contribute to the slower detection time.
Essentially your sensor just yells "I saw something" immediately, while the Aqara checks a few things first before letting you know.
That was my guess too but very hard to know for sure!
@@EverythingSmartHome well they HAVE to have some increased calculation time. To know which direction a person is moving they need to take multiple readings over a period of time to know where the person started and where they moved to.
I had a similar thought. It's possible the Aqara has two (or more) sensors built in that it needs to correlate to get additional speed, direction, noise data.
(It would surprise me if that took a few seconds though. But it could be that they do some kind of sample/sleep scheme for power reduction )
Looks pretty cool, thanks for sharing.
Well done Lewis! Great work. You just saved me a lot of bucks
Good job on the motion sensor!
Thanks! I havent soldered anything for 20 years (I think....) and wanted to pick it up again.....and I found a challenge here. top notch videoLewis 👍👍
Thanks! Good luck with the soldering! 😅
soooo excited! My cheap aqara sensors sadly suck. Please let this be easy! 😀
Absolutely fantastic stuff mate! I ordered 3 of these sensors the moment i was done watching this video yesterday, told a fellow home automation nerd friend of mine who also ordered 3 and i see now the sensor is out of stock pretty much eeeeverywhere, i hope you are happy! Haha! I am stocked to built and test as soon as the sensors arrive :D
Haha tell me about it, sold out immediately! Thanks buddy
@@EverythingSmartHome I'm the mate, glad Josh let me know early on this - received mine today. Having a play - cracking work bud!! Is the STL file available?
@@madmic1314 now I know where they are....send one over if you don't need em
@@dominicschober7889 I wish! Farnell totally screwed up the order - you were meant to get a sensor + packet of pin headers. The person packing that day obviously wasn't looking at what they were doing and instead got packs of pin headers.... now out of stock and have to wait 7-10 days for my money back 😕. The one I have working does work brilliantly, the esp reboots now and then, but think that's the debug setting for the logger component.
Very well done!
Thank you so much for sharing. I've just ordered the parts to make my own.
Awesome, enjoy!
This is why the engineer on the starship enterprise is Scottish. Well done sir for carrying on this amazing Scottish trait. Montgomery Scott would’ve been proud!
Seem perfect to complete pir sensor. Will make two for my house. Thanks Lewis, as always great content and perfectly explained !
Sadly they are out of stock. :/
Great video. This is awesome. This will be my next project. Thank you!
Let me know how it goes! Cheers
Just made one. Really awesome stuff. Thanks for the video! Any chance you’ll post the 3D files for the box ?
Had a delivery from DFRobot this morning. Soldered, programmed and encased in minutes. Works a treat! I can't thank you enough for alerting me to this project and the clear instructions to make it work. I am currently isolating with Covid, so it makes a nice distraction.
That's awesome, well done!
@Marc, You`ve got FB msg :)
You the man! Now we don't have to wait lol make our own!
This is a great video! I can’t wait to try this since the FP1 is nearly impossible to get.
Thanks appreciate it, good luck getting one!
Very nice project mate
Thank you buddy!
I would be really curious to see this with espresense. You can add a radar and pir to espresense. I currently have a PIR attached to my espresense in each room! works well! great video Lewis
Would be good to take a look at that for sure! Cheers Mark
So good to have someone “this side of the pond” who actually knows what they’re talking about!
Keep it up mate, 100k subs will be nothing soon, you will smash this!
Thanks so much, really means a lot!
great video. makes me want to make one, and gave me some ideas for a project in the works!
Nice one! 👌
Thanks for the great video!! Are you able to post details about the sensor enclosure?
Excellent! Out of stock everywhere I looked! Will have to wait.
Hope they are restocked soon
Inspired from your project i make my own 4 in one sensors and 2 in one sensors. Both the type off sensors works great.
Hey Lewis, any chance we could get the 3D print file? Thanks for everything!
Thanks for your video, I definitely will try to make one. FYI, Aqara FP1 is selling around £47 in China.
Very nice. I've used the RCWL-0516 microwave sensor combined with a PIR sensor for about 4 years. The main problem with the RCWL-0516 is the unadjustable range.
Atm im trying use the same module. But here in my house it detects beyond the concrete wall.
What’s the PIR sensor is for?
@@kevincostner8536 I use the PIR sensor as a trigger and MW as a condition. Then I use the MW sensor to turn of the lights when no one is in the area. Works well for areas where you don't move much like the couch. Placement is a bit fiddly because it detects thought walls (as you noticed).
Fantastic project, thank you for the tutorial. I'll definitely be looking into building some of these. How do you deal with light/dark in this case? Most PIR sensors also have an adjustable range in which they will activate.
I really love the idea of this sensor and I can feel the bug of an idea rattling around in my head, but I don't know what it is yet.
This is amazing, awesome job! I only wish I felt comfortable enough to try it myself. I would probably end up with like 10 in my house 😂
He Lewis, this looks awesome. I just ordered a few sensors and D1 mini's. Was looking for the design of the case, though - can you share that please? Keep up the great work - your videos are all awesome!!
I will do yeah there is a few little tweaks I need to make first as one of the clips that holds the board in was snapping too easily so just trying to fix that
I need this sensor! Now! ;--) thanks for the video ...
Nice video, thanks! I have been looking at something similar with a sensor I spotted on Aliexpress, the Hi-Link HLK-LD1125H. It is a 24GHz sensor that looks like it has similar capabilities for around £10. Seems it uses serial output as well so I'll have to try modifying the code you linked to. Now I just need to get a 3d printer so I can make nice cases like you do!
They look cool, thanks for the tip
@@tvathome562 please let us know if you made it work!
Wow, I am gonna order one right now🤩
Hope you got one!
Cool video! I was hoping this was an addon for ESPresence. Could you test that too? Would be a big win and the radar motion is integrated 😀
Have a look at RCWL-0516 module to add to the ESP32. It does require some fiddling with alu foil around the sensor to direct/limit the detection area, as it detects through glass and thin walls.
That would be nice for multi factor!
Oh and 🙏 thank you for this video/ solution.
Thanks!
That's so awesome!!!
Thanks man!
Thats awesome Lewis!! thank you so much .. I wanted to suggest a video if possible. Can you make a video on how you go about desiging 3d cases for your projects. You can actually make a video on how you designed the 3d Case for the sensor ( in this video ) . Please that would be awesome!!!
Thanks! I'd love too but I'm a really really big novice when it comes to 3d design, I just trial and error lots of stuff 😂
Amazing project! Will definitely get the sensor.
Could you please post the enclosure STL?
Any update on this? 😬😬😇
I made a case and posted the STL's. www.printables.com/model/229413-mmwave-esp8266-d1-mini-presence-sen0395-sensor-cas
@@erikroedig thanks! I'm trying to import the sensor to use it down here in Brazil.
and now all of these mmWave sensors are out of stock... good lord... what a great time to be alive!
I would buy a couple of these when you can set the sensitivity. Since we have a couple of cats this would be a mandatory feature 😊
you can set the sensitivity. He just didn't for some odd reason
Bought this sensor, couldn't get it working, eventually got a FP1. Now I see this tutorial 😂 Should have been patient
I literally did the same research after watching you previous video 😂😂😂 found the same product and formulated the same plan
Great minds huh 😅
I have been looking at this, and was thinking it would be great to team it up on the same board as espressence and a PIR. Would this push an esp32 too far?
I wish I had your knowledge and skills!
Hey I'm still learning every day! I'm sure you know lots I don't! 😅
@@EverythingSmartHome yeah me too, it’s like a minefield!
Just got mine today excited to try it out! want to figure out if it's affected by computer fans and if it can be hidden in cabinets
It likely will be unfortunately!
Hi great video, can you please share your 3D print layout? Thank you very much!
You CAN set the sensitivity on this sensor. Not sure why you haven't in this video. I had to turn mine way down to prevent detecting very minute motions. You'd have be not breathing and stone cold to not trigger it. I can send over an esphome config if you like. I also don't understand why people want to pair PIR with mmwave, as PIR isn't inherently quicker. It seems you've tried to compensate for a lack of sensitivity adjustment here with latency adjustment, which makes it slower. Mine turns the lights on the instant I come into the room. It's not possible for it to be any faster.
I really like the work you put into this. Very awesome! But, if its just detecting motion, I think for everyone else it is easier to just use the motion sensor.
Great video, again!
Btw could you also share a link where to find pin headers like that? Thanks!
Someone give this man an Oscar!
Only slightly annoyed that I just bought 4 aqara FP1s 😢 tbf I did Google this option haha -- great video! This video gave me the confidence to try it one day.
FP1s are very good and have some advantages over this!
@@EverythingSmartHome that does cheer me up a fair bit -- I'm looking forward to trying both and comparing 😊 keep up the good work mate, really enjoying the channel!
Great job! Any chance of posting the 3d model for the case somewhere? I saw posts a couple weeks back that you were still working on it. Wasn't sure if it was done yet? Thanks in advance!
Thanks! There has been some better ones posted in our Discord that I would probably recommend over my one to be honest, link in the description if interested!
Hey, what is the angle of detection for this sensor? Will it do fine if a mount it on a wall in a small room?
Very cool project but I'm looking for something that could also (somewhat reliably) detect a person falling: My grandma trips and falls all the times and someday she's gonna get seriously hurt.
The alarm system secondary function would be a great "cover" for installing it without having to explain her what function number one actually is and why she needs it.
Hellou, really good video :) is it possible to use something like this but outdoor? To protect open spaces? thanks
Thanks for this video!!!
I wonder how this sensor would work if you have cats or dogs? Which is a big problem for my home automations 😕
Do you have the stl for the 3d printed case? It's not in the description
Slashbanging stocks on the suppliers is kind of a neat complement of your content beeing informative and also unique :)
Sold out quick it seems 😅
@@EverythingSmartHome yup, all gone
I wonder how difficult it would be to use something like a 60GHz mmWave Sensor - Breathing and Heartbeat Module from Seeed Studio? Could it be utilized in the same fashion? And considering it is supposed to detect breathing and heartbeats, would it only pick up living occupants?
Crlogic from the HA thread linked has tested the Seeed one and doesn't rate it nearly as much
I was following the "XeThru" sensors that did breathing rate since about 2016 or so lusting after them for every room in my house. Glad to see if finally becoming mainstream and even better cheap as the XeThru dev modules were like $400+ :D
*note we crlogic and I have not tested the 60ghz one but only the 24ghz one
Thanks for the update Philip, good work!
Is there any chance to be able to disable the red blinking led on the mmwave sensor ? great tutorial by the way !
What do you think about thermal occupancy sensors, like the AMG8833?
A guy in the LTT Jasco video comments said he built a great solution for just $30 using that sensor, he says the the system can detect body heat and know if the room is in use, even if you're laying on the couch and not moving. Would fix the window curtain issue for sure!
That is awesome! Suggestion: could you use a PIR to switch on the lights and also trigger the radar to wake from sleep, with the radar going back to sleep when the lights go off? Could save lots of power.
How much power are we talking about?
@@thesimbon That's a good question, but the ESP8266 is not known for being frugal. Given the price of energy I like to keep the consumption of anything that's on 24/7 to a minimum, and since Lewis already mentioned coupling it with a PIR for room entry detection this seemed like an easy win.
I guess you could, although even at today's energy prices the savings would be very very minimal I think
@@EverythingSmartHome Any idea what the consumption of your sensor is? It's likely to be the WiFi rather than the radar that dominates it, I reckon, but it would be interesting to know.
@@cooperised esp8266 still takes time to boot after sleep and that would ruin the fast response time of the sensor. It would be nice to have tasmota or similar able to take advantage of low power processor in esp32
Thank you for your greath video. Can you configure the sensos so it can "see" the difference between a pet and a person?
A setup wich scans above my dogs or is it a big angle?
Unfortunately no it just detects all motion
@@EverythingSmartHome Should, for example, a metal plate help to reduce the beam "scanning" the floor or will it penetrate the plate?
Maybe I need to buy one and test is ;)
Back in stock at DFRobot.
And... out of stock again. Good thing I nabbed one!
Brilliant
Thanks!!
Hi, I have a quite big open room, including kitchen, living room and dinning room in one. Kind of want 2 of them in the same location, directed in different directions. Is there any intelligence here or will they just interfere with each other? I guess you can put some metal in the back to make some shielding. Being able to use different frequencies or codes would be great. Any such features?
Great videos, however no article just yet? or I missed it somewhere?
Do you have a link to the stl for the case?
Looks awesome, waiting for the sensor to become cheaper
Hey , i saw ur video . i thought i could work with sp8266 node mcu . I have a doubt i need to detect presence only . As you had mentioned ,we need to use io2 pin for sending binary . so my doubt is : is there a pin that i need to mention in my code ?
Hi, great guide and and awesome that you share this with us.
I am looking to make this but found that DFrobot also has a smaler sensor mmWave Radar Sensor Arduino-Human Presence Detection Wiki - DFRobot
You think this will work also, similar spec but on the 5.8GHz band.
And cheeper.
Want to do around 10pcs so finding a similar but cheaper sensor would be awsome.
Fantastic! Thank you! I do not see the written article on your site.
Will get it added tomorrow 👍
@@EverythingSmartHome Still cannot see the written article.
Could you please post the STL file for the black housing casing, I can also use it for other D1 contraptions!
Aqara FP1 have Precense Event entity which update as fast as PIR. Thats what I used for lights.
I put one together and it works well, but there's a red light that constantly flashes. How can I either disable the light, or maybe better, make the light flash once when motion is initially detected?
Is there an option to detect distance? Something fine enough to detect if something is 1 meter close or 3 meter away, doesn't have to be very fine resolution. Thinking about detecting the kids when standing too close to the tv to Pause the tv
So cool. I hope I'll actually get those boards from Mouser mid June though ;-)
I hope so too!
This is awesome! Can't wait to try it.
Looking for the link to the case file to print, am I missing something?
I'm still working out a few little kinks and I'll add it - some of the clips that hold the wemos break too easily
@@EverythingSmartHome awesome thank you!
@@EverythingSmartHome any updates on this?
