Air quality sensor system delivered on a single chip
The SGP40 is Sensirion’s digital volatile organic compounds (VOC) sensor designed for easy integration into air treatment devices and air quality monitors.
It is in stock at distributor Digi-Key Electronics.
Based on Sensirion’s CMOSens technology, the SGP40 offers a complete sensor system on a single chip and features a digital I²C interface, 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 for applications such as triggering the gradual fan control of an air treatment device.
Both the SGP40 chip and VOC algorithm feature robustness in the final application over their lifetimes.
Pushing the multi-pixel and multi-hotplate approach to the next level of individual control of each sensing element, the SGP40 enables a drastic reduction in power consumption, making it suitable for battery-driven applications as well.
