I have an air sensor, now what?

It’s not always clear what your air sensors data means, especially if you’re trying to compare them to the air quality data found on our website.

Air sensors give readings every minute, or even instantaneously; our regulatory monitoring is reported hourly or daily. We use these longer time scales because there is a proven link between daily air quality levels and health effects. The Air Quality Index (AQI) is based on daily values. There currently is no equivalent for air sensors.

However, the EPA has launched a new tool to make instantaneous outdoor air quality data useful for the public. Their new “sensor scale” is designed to be used with air quality sensors that provide data in short time increments – often as little as one minute. EPA developed the scale to help people understand the one-minute data the sensors provide and how to use sensor data as an additional tool for planning outdoor activities.
