How Does a TVOC Sensor Actually Work?

What the sensor is actually measuring is the electrical resistance of this metal-oxide layer. This real time measurement and output of resistance is the first step in obtaining our TVOC reading. The change in resistance across the surface of the sensor is directly proportional to the change in concentration of the target gas(es). The exact ...
