Air Quality Sensors

Using Sensors to Understand Air Quality

Air sensors are lower-cost, portable devices that can estimate concentrations of some air pollutants. There are many sensors on the market that are available to anyone. Prices start around $200.

In the Spokane-area, the use of personal air quality sensors is growing. Private individuals, as well as organizations like schools, libraries, sport associations, and outdoor event organizers are using sensors as a tool to better understand air quality conditions at their location(s).

Although sensors may provide less accurate data than the data we provide from the regulatory monitors, we support and encourage the use of air quality sensors. We believe they can be a useful tool for residents, educators, and students to explore indoor and outdoor air quality.

Air Sensors at Schools

Air sensors are great tools for educators to engage with their students around the topic of air quality. With the assistance of a state grant and support from three local business sponsors, Spokane Clean Air implemented the Kids Making Sense® program in eight pilot schools during the 2022-23 school year. Teachers from each school completed their trainings in November and implemented the program in their classrooms. Read more in this pilot program report.

WE ARE RECRUITING middle and high schools in Spokane County to participate during the 2023-24 school year! We ask that you send two educators to the next round of Kids Making Sense® (KMS) trainings. By attending the training, each school receives a KMS classroom kit valued at $2600. Contact Lisa Woodard at LWoodard@spokanecleanair.org and reserve today!

Special thanks to these participating organization and sponsors:

  • Washington State Department of Ecology
  • Spokane Public Library and Spokane County Library District
  • Spokane Public Schools
  • Cheney School District
  • Medical Lake School District
  • West Valley School District
  • Avista
  • Central Pre-Mix/Inland Asphalt
  • Hotstart Thermal Management

Air Sensors at Libraries

In partnership with our two public library systems in Spokane County, every branch location has an indoor and outdoor air quality sensor installed. These are stationary PurpleAir® sensors. Data from these sensors, and from those located across the globe, are available for viewing here.

We have partnered with Spokane Public Library to provide a pilot Sensor Loan Program. Interested individuals can check-out a hand-held sensor kit to conduct their own air quality observations. Our sensor lending program will be piloted at the Central Library in downtown Spokane in September 2023.

These programs are made possible by a grant from the Washington State Department of Ecology. Funding was also provided by these local companies: Avista, Central Pre-Mix/Inland Asphalt, and Hotstart Thermal Management.
