Gas sensors offer stability for environmental monitoring

The gas sensor integrates four sensing elements with intelligent algorithms and pattern recognition to detect the type and concentration of gases and measure key environmental parameters, including relative humidity, temperature, volatile organic compounds (VOCs), particulate matter (PM2.5), and CO₂.

For VOCs that are simultaneously present in the air, the SGP devices feature a total VOC (TVOC) output capability, which enable the device to measure in-depth air quality information and survey indoor environments for contamination in one of the most practical and cost-effective ways possible.

The strength of Sensirion’s multi-pixel gas sensor SGP lies with its stability over time, high sensitivity and fast response in measuring certain types of chemical compounds and impurities.

Traditional metal-oxide gas sensors may degrade due to these environmental contaminants; the proprietary metal-oxide technology and multi-pixel platform found in the SGP devices offer unrivaled robustness that result in unique long-term stability, accuracy and resistance against contamination from siloxanes.

Sensirion’s multi-pixel SGP gas sensor devices are available in a very small 2.45 × 2.45 × 0.90 mm, 6-pin DFN package, and can be easily integrated into a variety of consumer wearables, smartphones, tablets, industrial ventilation devices and Internet of Things (IoT) applications.
