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.

Cool. A few years ago I made similar sensors (but just PIR, LUX, esp8266 board, jumper wires, and some with ultrasonic proximity). Attached them to the wall with those 3m velcro things. ESPHome makes things so easy; didn’t even have to write code. Hardest thing was designing and iterating over the case to get the tolerances just right.
