AirSentry Unit

AirSentry Unit

Compact, Solar-Powered, Ambient Air Quality, Pollutant, and Ozone Precursor Detection

How it works:

A solar-powered, cloud-native network connected ambient air quality and pollutant monitor that provides continuous and reliable data in real-time. With WiFi and cellular LTE connectivity, The Air Sentry unit is a wireless solution for providing cloud based air quality monitoring and logging in any location. Standardly equipped with Total Volatile Organic Compound (TVOC) and Particulate Matter (PM2.5) sensors plus meteorological sensors, multiple units can be stationed around your location to provide an accurate, real-time assessment of current pollutant and air quality levels at your site. Additional sensor options such as methane, ozone precursor, H2S, and more can be added for additional capabilities such as methane emissions tracking. Plus, with precise and accurate sensors for wind and weather data, the Air Sentry system provides users with comprehensive data to meet state and federal reporting standards, in addition to parameters for algorithmic dispersion modeling of pollutants and emissions.
