How to Use Air Sensors: Air Sensor Guidebook | US EPA

Sometimes these sensors may not report air quality in traditional concentration units. However, users may still find measurements made by these unitless scales or colors to be useful for making relative comparisons. The uncertainty in these types of measurements is quite large. The expectation would be that the air pollution sensor is directionally consistent with pollutant trends; for example ...
