TuYa TS0601 Air quality Sensor : unit error ?
What happened?
in the descriptive note, the units given for this sensor are:
- VOC: ppm
- formaldehyd: mg/m3
However, in the Tuya application, these two data appear:
- VOC: with a factor /100 (0.10 ppm instead of 10 ppm)
- formaldehyd: µg/m³ and not g/m3
Given the role of these sensors, these differences are decisive because if the units are correct then the air is very dangerous (including within the given measurement range).

Ce sujet aborde le problème mais très partiellement et sans correction réelle : https://github.com/zigpy/zha-device-handlers/issues/953
What did you expect to happen?
Identify and check if the units are correct
How to reproduce it (minimal and precise)
i have two devices. Same conclusions.

Yeah this sensor data does not make any sense, if I look at the numbers I should have been dead already. Especially formaldehyde levels. Definitely has problems with units, but in general this is a rubbish sensor
