General Description

The Qingping Air Monitor Lite is an air quality monitoring device that provides real-time measurements of PM2.5 and PM10 mass concentrations, CO2 concentrations and environmental parameters such as temperature and relative humidity. Historical data can be visualized on the app and can be sent to email as a .csv file via app.

Principle of Operation

The Qingping Air Monitor Lite uses a Grandway PM7500 as the PM raw sensor. The measurement principle is based on laser scattering. It converts the signal to particle mass concentration using proprietary algorithms.
