New Small, Low-Power, MOX VOC Sensors: How Might They Be Used for Indoor Air Quality Monitoring?

Stories in the news media are heightening people’s awareness of the importance of the quality of the air we breathe both indoors and out. The average human inhales about 15kg of air a day, 80% of it indoors. And while the quality of outdoor air is routinely monitored by public agencies, Indoor Air Quality (IAQ) monitoring is the responsibility of the building’s operator or occupier. A new generation of small, surface-mount, low-power VOC (volatile organic compound) gas sensors offering the potential for distributed, local IAQ monitoring by small and affordable devices, and therefore for more responsive operation of air-moving and air-filtering equipment in buildings.

This article explains the operation of these new VOC sensors and the differences between them and absolute single-gas sensors. It also shows how they can provide data which enables air management equipment to respond most efficiently and effectively to variations in indoor air quality. Download now!
