TVOC Gas Sensor AGS02MA User manual

When the applied voltage of the sensor module is too high, for example, the applied voltage exceeds , it will directly cause irrecoverable damage to the sensor module. When the positive and negative poles of the sensor are reversed, it will also cause damage to the sensor circuit. As a result, the sensor module does not work.

Understanding TVOC: What You Need To Know About Volatile ...

Thus, a measurement known as TVOC was adopted to measure the overall amount of VOCs in a given space. Total volatile organic compounds (TVOC) is a group of VOCs used to represent the entire pool of pollutants. If you have an air quality monitor with volatile organic compound detection capabilities, you will see your readings in terms of TVOC.
