The SGP40 Air Quality sensor adopts the new SGP40 digital VOC sensor chip launched by the well-known Sensirion. Based on the Sensirion’s 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 Sensirion’s powerful VOC algorithm, the sensor signal can be directly used to evaluate indoor air quality. It features low power(2.6mA), and fast response(2s). The data from the sensor can be directly used to evaluate air quality without calibration.

With compact and small body, this Breakout SGP40 Air Quality sensor is very suitable for indoor projects that will be used for a long time, such as refitting air purifiers, kitchen hoods, etc. Besides, we provide you with C and Python libraries for using with different main-controllers.

Note: VOC index is obtained by converting the detected ethanol equivalent in air.
