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

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 are built equal. Similar technology is used throughout, however, which is what we will explore below:

Adafruit SGP30 TVOC/eCO2 Gas Sensor

· While the sensor is off, baseline values are valid for a maximum of seven days. Restarting the sensor without reading back a previously stored baseline will result in the sensor trying to determine a new baseline. The adjustement algorithm will be accelerated for 12hrs which is the Maximum time required to find a new baseline.

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;

BME680 TVOC output does not seem correct

· The BME680 is a great sensor to track tVOC levels, but is not selective to specific compounds, and as other sensors working on a similar MOX sensing technology, such devices cannot output an absolute tVOC level. One could derive a tVOC-equivalent estimation based on the sensor's outputs history, but as such these 'equivalent estimations' may slightly vary between use-cases and …
