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/

I don't have HVAC, so I'm just using it to see when the air at my desk is getting stale so I remember to open the window. I mostly use homeassistant for the configuration, although I might also set up a notification at some point (I only got my sensor 2 days ago)

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.
