The SGP gas sensor is based on Sensirion’s multi-pixel platform, which integrates four gas sensing elements into 2.45 x 2.45 x 0.9 mm3 DFN package featuring a calibrated air quality output signal. The combination of long-term stability and multi-pixel technology opens up possibilities for environmental monitoring in smart home, appliances and Internet of Things applications. The SGP allows the integration of metal-oxide gas sensors into mobile devices.
Traditional metal-oxide gas sensors suffer from poor long-term stability including a loss of sensitivity and an increase in response time. This degradation is caused through irreversible contamination by certain chemical compounds, which are ubiquitous in real-life applications due to their widespread use in consumer products and production environments. Sensirion’s proprietary metal-oxide technology and multi-pixel platform provide the SGP against these contaminants resulting in long-term stability and accuracy.
