SGP40 Air Quality sensor
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 body. The data from the sensor can be directly used to evaluate air quality without calibration. Integrated with 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 using with different main-controllers.
Note: VOC index is obtained by converting the detected ethanol equivalent in air.
VOC Index
VOC Index | Air Quality | Suggested Action |
---|---|---|
0-100 | Excellent | No measures needed |
100-200 | Good | No measures needed |
200-300 | Lightly Polluted | Ventilation suggested |
300-400 | Moderately Polluted | Increase ventilation with clean air |
400-500 | Heavily Polluted | Optimize ventilation |
- The sensor provides the change of air quality trend, and the algorithm will continuously adjust the baseline of typical air according to historical data. The longer the sensor is used, the better the sensitivity and accuracy of trend and change.
- In the normal air environment, the sensor can obtain the accurate VOC index immediately after use; in the heavily-polluted environment, the sensor can obtain the accurate VOC index after use for about 1 hour. It is recommended to integrate it into the long-term indoor projects.
