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/

Not speaking for Mr Lemon, but for me CO2 levels are an interesting metric to trigger my air exchanger / HVAC fan combo for in a given zone, since it indicates stale air in general.

Same ^

CO2 sensor for me is the most important.

Good to know, maybe I'll add a MH-Z19.
