How Does a TVOC Sensor Actually Work? Kaiterra

What the sensor is actually measuring is the electrical resistance of this metaloxide 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 degree to which the resistance will change (that is, the ratio or equation that …

TVOC und eCO2 Sensoren • Wolles Elektronikkiste

· The TVOC and eCO2 sensors give trends, nothing more. If you really want to monitor the CO2 content of the room air, you’d better use the slightly more expensive NDIR CO2 sensors. SGP40 . Meanwhile, there is a successor model of the SGP30, namely the SGP40. Instead of TVOC and eCO2 values, this device provides a dimensionless index between 0 and 500. For me, this seems like a good approach, since an eCO2 …

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 ...
