Adafruit SGP30 TVOC/eCO2 Gas Sensor

Dec 07, 2020· 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;

VOC Sensors and Monitors Volatile Organic Compounds

Both sensor types are nonselective which means they can be used for measuring a wide variety of VOCs. To achieve this they have been calibrated against isobutylene that allows them to respond to a wide range of VOCs at varying degrees of sensitivity. Each type has a calibrated measurement range against a set of VOCs.
