How Does a TVOC Sensor Actually Work?

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 …

Adafruit SGP30 TVOC/eCO2 Gas Sensor

· The sensor to sensor variation of SGP30 in terms of sensitivity is very good as each of them is calibrated. But the baseline has to be determined for each sensor individually during the first Operation. To make that easy, SGP lets you query the ''baseline calibration readings'' from the sensor with code like this: uint16_t TVOC_base, eCO2_base;
