How Does a TVOC Sensor Actually Work? - Kaiterra

For the continuous monitoring of TVOC, MOS sensors are generally used. This is a broad category, and sensors across this category provide varying degrees of quality in their readings - not all MOS sensors are built equal. Similar technology is used throughout, however, which is what we will explore below:

How to Recalibrate the TVOC Sensor – Awair Support

Element's TVOC readings are relative to its environment and the sensor calibrates as such. When a device is moved to a new environment it needs to calibrate to that space. This can mean that two different devices that have been measuring different environments can have different readings when moved to the same space. To create consistency the TVOC sensor needs to be recalibrated, this can now ...
