Aqara TVOC Sensor (review) : Aqara

The Aqara TVOC sensor measures VOCs (Volatile Organic Compounds), temperature, and humidity levels. It’s HomeKit compatible via a suitable Aqara hub and exposes all three sensors to HomeKit. The sensor does essentially the same job as the Eve Room, and like the Eve product, it uses an EInk display. It uses 2 x CR2450 batteries that should last well over a year (I’ve had it for 5 months ...

About TVOC and the Laser Egg+ Chemical

How the Laser Egg+ Chemical measures TVOC? A metaloxidesemiconductor(MOS) sensor is used in the Laser Egg to measure TVOC concentration. To ensure measurements remain accurate throughout the sensor’s lifetime, the sensor is continually selfcalibrating: the lowest reading is used as a baseline, and all given TVOC readings are relative to this baseline. For the first 5 minutes of powering ...
