Only Sensor (5, 4, 8-AQ, and 2-TH): The only DIY home automation sensor you'll ever need
(lemmy-ui.nowsci.com:33443)
Hey all,
A couple of weeks ago I posted my 3D printable pegboard organizers, and today I’m releasing the Only Sensor line of home automation sensors.
Fully free and open, complete with wiring diagrams, cases, component bill of materials, and instructions for assembly.
You source and build them yourself, with acquisition costs ranging from $2-$35 to build, and options for:
- mmWave presence
- PIR motion detection
- Temperature
- Humidity
- LUX
- PM <10µm AQI
- PM <2.5µm AQI
- PM <1µm AQI
- NOX
- VOC
All integrate with Home Assistant via ESPHome.

It certainly did to me when I made these. I ended up using an old Android phone for that part, but many members of the ESPHome community working with these sensors use it and have never reported a problem. HLK are the original manufacturers of the LD radar chips.
