HabitatMap - AirBeam2

General Description

The AirBeam2 by HabitatMap is an open-source platform that measures particulate matter (PM₁, PM_2.5 and PM₁₀), temperature and relative humidity.

Principle of Operation

The AirBeam2 uses a light scattering method to measure PM. Air is drawn through a sensing chamber wherein light from a laser scatters off particles in the airstream. This light scatter is registered by a detector and converted into a measurement that estimates the number of particles in the air.

Via Bluetooth, these measurements are communicated approximately once a second to the AirCasting Android app, which maps and graphs the data in real time on a smartphone. Via Wi-Fi, these measurements are communicated approximately once a minute to the AirCasting website. At the end of each AirCasting session, the collected data is sent to the AirCasting website, where the data is crowdsourced with data from other AirCasters to generate heat maps indicating where PM_2.5 concentrations are highest and lowest.
