How Does a TVOC Sensor Actually Work?

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:

Choosing an Air Quality Sensor | Details |

At the beginning of the project I was not sure about the type of sensor I should use, which is best an which would be available due to Chip shortage. So i deciced to make this module in my desk lamp as interchangable as possible. Fortuanetly most of these Senesors are availible as a breakout board. And most of them have the same pinning. These Sensors have been in my focus: SGP30(Temp, eCO2 ...

THE FUTURE IS WHAT WE MAKE IT C7364A Wall TVOC Sensor

The TVOC wall sensor installs directly on a standard electrical box and should be mounted five feet from the floor of the area to be controlled. Do not mount the sensor near doors, opening windows, supply air diffusers or other known air disturbances. Avoid areas where the detector is exposed to vibrations or rapid temperature changes.
