General Description

The QuantAQ MODULAIR-PM sensor is an air quality monitoring device that provides real-time measurements of PM1.0, PM2.5 and PM­10 mass concentrations and environmental parameters such as temperature and relative humidity. Data can be visualized and accessed on the QuantAQ dashboard.

Principle of Operation

The QuantAQ MODULAIR-PM sensors use a Plantower PMS5003 and an Alphasense OPC-N3 particle sensor. The particle counts across a wide range of particle diameters are converted to PM1.0, PM2.5 and PM10 mass concentrations in μg/m3 using proprietary algorithms.
