Gas sensors offer long-term stability for environmental monitoring

Mouser now stocks the multi-pixel Sensirion Gas Platform (SGP) devices. Among the only long-term stable siloxane-resistant MEMS gas sensors in the market today, the devices are ideal for integration into mobile devices for reporting indoor air quality, measuring breath alcohol concentration, or recognizing smells. This multi-pixel gas sensor SGP 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, VOCs, PM2.5, and CO2. For VOCs that are simultaneously present in the air, the SGP devices feature a 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 the company’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. The company’s gas sensor devices are available in a very small 2.45mm × 2.45mm × 0.90mm, six-pin DFN package, and can be easily integrated into a variety of consumer wearables, smartphones, tablets, industrial ventilation devices and IoT applications.
