This DIY mmWave Presence Sensor Changed Everything - LD1125H | digiblurDIY

Cool stuff as usual, Travis!

I just received mine, and it works great. Thanks so much for bringing this sensor to our attention (and your write up)!!

Thanks for the inspiration!!

Travis, Another great video from the Digi Team. Glad you were able to find a suitable, inexpensive, and reliable millimeter (mm) wave sensor, coupled with a true DIY solution (ESP32) for us (the kids who aren't like the rest 😉). Great job to you and OG! 🙂

People looking at his ceiling: "Is he filming me?" 😅

Very nice guide 👍

I totally agree, most exciting sensor in a long time. Now it's a waiting game for a decent commercial non wifi, cloud free sensor to be available.

Ohhh, you're "in the ceiling" boxes, combined with "false triggering through the wall" has got me planning a mass deployment inside my attic, looking down in multiple locations, right through the drywall ceiling. No visible sensors at all ...

I'm new to the whole Home Assistant/Home Automation rabbit hole. I'm a developer by trade and have some electronics training, so I'm not afraid of a bit of soldering or code. I came across this video looking for a DIY presence sensor. I love your fun, but straight forward info. I had to subscribe after seeing this video!

Would love to see the automations that are used. I am having trouble with them trying to find the pattern of the sensor to trip the lights. Again thanks for a great video.

Lol...I love this guy. Yeah dude it's killer👊

Goodjob for your video 👍, do you have a idea how to do this for a new house (DC, location) please

I made one of these and have been using it for about a week now and love it! I no longer have to use my motion sensor in my office and planning to order a few more! Working on a 3D case for it now, probably won't be the prettiest thing, but functional. Thank you for the video tutorial!

Thanks, Travis. Bought them, they are blasting through doors as a quick test. Will install in toilet ceiling and try to compare the distance <1.5m = near sink with lights = turn on relay for light >1.5m = in the toilet seat :) start the timer for ventilation activation if sitting more than 2 minutes.

Finally got around to building this. Excellent tutorial Travis. Did anyone come up with a brilliant design for a case yet?

Loved the video and the walkthrough along with your other one explaining why you chose this sensor that I had to make one myself. However, I wanted to use some Wemos Lolin S3 Mini boards I had and no matter what I change, I cannot get the code to compile per the board: lolin_s3_mini and variant: esp32s3 options. I'm open to any ideas!

Gravy baby! New subscriber.👍

Oh btw...I subscribed & like this. I've been an engineer for a few decades now but totally a hands on & DIY guy & LOVE learning about new technology, especially in the digital world since I'm a mechanical/packaging engineer & this is not my strength...yet But have three 3D printers now and working on a haptics design involving mini-controllers, ESP tech, VR & the hardware (body) designing. So really a wide spectrum. The last 6+ yrs I've used the Arduino here & there on some things. This home automation though is on my list of projects after I finish installing a mini-split heat pump at my little house in LA. Got here from Chicago a few years ago & 4 miles from Pacific & u would be surprised how damp & chilly the nights are! Holy cow Anyway these mini sensors and how easy we can design & integrate them into a home monitoring system is unreal. I want to have a bunch of custom 3D printed cases around my place that can monitor temp, humidity, wind speed & direction, sense movement outdoors around me, and if possible the quality of air. ESPHome seems like an excellent choice for this. Couple questions if you would be so kind to answer: :) Can this data collected in ESPHome be put into graphic visual display gauges instead of raw data form? Is this ESPHome the best open source option, for collecting a wide range of data in a local area like your home or office? 1 goal I've always had is having all this sensing data to be not on your phone, but on your wrist. Where a haptic vibration gives you alerts. Wherever I'm at if a delivery is made to my door, the haptic vibration goes off...for example. PLus allowing me a small watch screen 2 view all all the data or gauges. I have my phone w/me going out like everybody else...but not attached 2 my body where I can get silent notices...and very fast access for viewing. Sorry for the long post! My mind races with excitement Cheers

Athom made a one that looks good

Thanks again for another great video. Does anyone have an STL for a 3d printed box for this project if not using a cover plate?
