The AirBeam by HabitatMap is an open-source platform that measures fine particulate matter, namely PM2.5
Principle of Operation
The AirBeam uses a light scattering method to measure PM2.5
. Air is drawn through a sensing chamber wherein light from an LED bulb 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. 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 PM2.5
concentrations are highest and lowest.
