Description

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), fast response(2s), and small size. The data from the sensor can be directly used to evaluate air quality without calibration.

Integrated with an easy-to-connect Gravity interface, this Gravity 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 use with different main controllers.

Applications:

Air Purifiers
Kitchen Hoods
Demand-controlled Ventilation
Thermostats
Indoor Air Quality Monitoring

Features:

Ultra-low power consumption(2.6mA)
Built-in temperature and humidity compensation, no need to calibrate
VOC index for direct air quality indication
