Multi-pixel gas sensor

15 November 2017 Electronics Technology

Based on Sensirion’s innovative MOXSens technology, the SGP multi-pixel gas sensor offers a unique combination of long-term stability and multi-pixel technology that opens up new possibilities for environmental monitoring.

Traditional metal-oxide gas sensors suffer from poor long-term stability caused through irreversible contamination by siloxanes. MOXSens technology provides the SGP with an unmatched robustness against these contaminants that results in unique long-term stability and accuracy. The chip integrates four gas sensing elements into a very small 2,45 x 2,45 x 0,9 mm DFN package.

The SGP30 has been designed for smart home, appliance and Internet of Things applications. It features two calibrated air quality signals and on-chip humidity compensation. In addition, with the SGPC3, Sensirion offers a low-power solution that makes reliable gas sensing available for mobile applications.

Evaluation and testing is supported by application notes and example code; the SGP evaluation kits are also available through Sensirion’s distribution network.
