Air quality sensor helps cut power consumption

This indoor air quality sensor is an integrated CMOSens sensor system on a single chip based on a metal-oxide sensor.

The sensor provides a humidity-compensated indoor air quality signal via a digital I²C interface.

SGP40 uses Sensirion's MOXSens Technology, which offers robustness against contamination by siloxanes and results in long-term stability in terms of sensitivity and response time.

Using sensing material and micro-hotplate technology, the SGP40 offers a drastic reduction in power consumption, making it suitable for battery-driven applications.

Applications for the Sensirion SGP40 include air purifiers, kitchen hoods, demand-controlled ventilation, thermostats, and indoor air quality monitoring.
