The SGP gas sensor is a 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 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. The SGP allows for the first time the integration of metal-oxide gas sensors into mobile devices.
Traditional metal-oxide gas sensors suffer from poor long-term stability including a rapid loss of sensitivity and a strong 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 with robustness against contaminants resulting in unique long-term stability and accuracy.
