The multi-pixel gas sensor SGP opens up new possibilities for the measurement of indoor air quality. The long-term stable metal-oxide gas sensor features multiple sensing elements on one chip providing in-depth information on air quality. The SGP gas sensor is based on Sensirions multi-pixel platform, which integrates four gas sensing elements into a very small 2.45 x 2.45 x 0.9 mm3 DFN package featuring a fully calibrated air quality output signal. The unprecedented combination of long-term stability and multi-pixel technology opens up new possibilities for environmental monitoring in smart home, appliances and Internet of Things applications.
