Gravity: SGP40 Air Quality Sensor Brand_M5Stack The case is compatible withThe 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
