Davis Instruments - Airlink

General Description

The Davis Instruments Airlink sensor is an air quality monitoring device that provides real-time measurements of PM1.0, PM2.5 and PM­10 mass concentrations, global air quality indices (AQI) and environmental parameters such as temperature, dew point, wet bulb temperature, heat index and relative humidity. Data can be visualized and accessed on the dashboard and mobile applications. The Airlink sensors can be used as stand-alone sensors or paired with a Davis weather station.

Principle of Operation

The Davis Instruments Airlink sensors use a PMSA003 laser particle counter, where laser beams detect particles by their reflectivity. These sensors count suspended particles in sizes of 0.3, 1.0, 2.5 and 10 μm. These particle counts are processed by the sensor using a complex algorithm to calculate the PM1.0, PM2.5 and PM10 mass in μg/m3. The PMSA003 sensors come factory calibrated.
