How does Atmotube VOC sensor work?

SGP sensors are calibrated with ethanol, which serves as a reliable and economical proxy for TVOC. This can be verified by comparison between the reponse of the SGP to ethanol and to an ISO normed two kinds of VOC gas mix that represents TVOC. Within a large target gas concentration range, the SGP reveals a similar gain for both of those target gas compounds (compare similar slopes in Figure ...

How Does a TVOC Sensor Actually Work? - Kaiterra

While lab-based measurements may be highly accurate, they are unable to provide a continuous measurement of TVOC, which is incredibly important and, some may even argue, more important than having a perfectly accurate value for a specific gas. What Is an MOS Sensor? 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 …
