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.

All the details can be found at: https://nowsci.com/only-sensor/

Yea I've considered recommending thr DHT22 instead, but I was trying to keep costs as low as possible, and honestly I've had pretty good results thus far (calibrating with other systems, anyway).

Bme280 is actually just as cheap if not cheaper than the dht sensors. But its a fair point trying to keep the cost down. I definitely like that philosophy, but if the quality suffers too much it's just not worth the trouble. Keep up the good work. 😎
