Be Air Smart

Air Quality Sensor Program

Ready to Measure Air Pollution in your Area?

We are proud to collaborate with the Clean Air Force of Central Texas, and Austin FC |Atlas to support air quality education by providing free Particulate Matter (PM) sensors to local organizations throughout Central Texas.

One of Air Central Texas’s primary goals is to ensure that everyone in the region is ‘Air Aware’, which is the Air Central Texas way of saying educated on local air quality.

This program empowers children, one of the most sensitive groups to air pollution, with the tools to better understand air quality by using a hyper-local outdoor particulate matter (PM) sensor that provides real-time information on air quality conditions.

Our ideal partners would be Schools, Libraries, Youth Education Organizations, Children’s Hospitals, Clinics, and Daycares/After-School Programs located within the Austin-Round Rock-San Marcos MSA (Bastrop, Caldwell, Hays, Travis, and Williamson counties).
