Gravity: SGP40 Air Quality Sensor Brand_M5Stack and python)The SGP40 Air Quality sensor adopts the new SGP40 digital VOC sensor chip launched by the well known Sensirion. Based on the Sensirions CMOSens technology, the SGP40 offers a complete sensor system on a single chip, a temperature controlled micro hotplate and a humidity compensated indoor air quality signal. In combination with Sensirions powerful VOC algorithm, the sensor signal can be directly used to evaluate indoor air quality. It features low
