General Description

The AS-LUNG sensors (i.e. Portable and Station) are designed for air quality research and provides real-time measurements of PM1, PM2.5 and PM10 mass concentrations as well as carbon dioxide concentrations.  AS-LUNG offers portable and stationary mount versions that share common components and can be transformed to different versions. Its wide–connectivity and powering design enables easy deployments in different sites.

Principle of Operation

AS-LUNG uses Plantower PMS3003 laser particle counter, where laser beams detect particles going past by their reflectivity. These sensors count suspended particles in sizes of 0.3, 0.5, 1.0, 2.5, 5.0 and 10 µm. These particle counts are processed by the sensor using a complex algorithm to calculate the PM1.0, PM2.5 & PM10 mass in µg/m3. PMS3003 sensors come factory calibrated.
