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/

    Interesting. The AirGradient sensors are exactly what I’m trying to avoid with the OS, considering their price tag. MH-Z19 sensors might be a good direction for me to go.
