Product Summary

The SGP40 is a digital gas sensor designed for easy

integration into air purifiers or demand-controlled

offers a complete, easy-to-use sensor system on a single

controlled micro hotplate, providing a humidity-

compensated VOC based indoor air quality signal. The

output signal can be directly processed by Sensirion’s

powerful VOC Algorithm to translate the raw signal into a

VOC Index as a robust measure for indoor air quality. The

VOC Algorithm automatically adapts to the environment

the sensor is exposed to. Both sensing element and

VOC Algorithm feature an unmatched robustness

against contaminating gases present in real-world

applications enabling a unique long-term stability as

well as low drift and device-to-device variation. The very

applications

in

limited

spaces.

Sensirion’s

state-of-the-art production process guarantees high

reproducibility and reliability. Tape and reel packaging

together with suitability for standard SMD assembly

processes make the SGP40 predestined for high-

volume applications.
