Presented By HabitatMap
Goal Crowdsource air quality data & clear the air!
Task Record and share air quality measurements.
Where Global, anywhere on the planet

AirCasting is an open-source, end-to-end solution for collecting, displaying, and sharing health and environmental data using your smartphone. The platform consists of wearable sensors that detect changes in your environment and physiology, including a palm-sized air quality monitor called the AirBeam, the AirCasting Android app, the AirCasting website, and wearable LED accessories. By documenting and leveraging health and environmental data to inform personal decision-making and public policy, the AirCasting platform empowers citizen scientists and changemakers.

How to Join

Buy an AirBeam,, and monitor your air for pollution.

The AirBeam uses a light scattering method to measure fine particulate matter or 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. Why is this important? The US Environmental Protection Agency monitors and regulates six criteria air pollutants, one of which is PM2.5, and the EPA’s measurements indicate that PM2.5 levels pose a substantial health risk in cities across the country.

Via Bluetooth, the AirBeam measurements are communicated once a second to the AirCasting Android app, which maps and graphs the data in real time on your 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.

As an open-source platform, modifying our components to take other measurements and or transmit the data to other websites or apps is easy and encouraged. We’ve even included an expansion port on the AirBeam to make adding sensors as simple as can be.
