AIR: Area’s Immediate Reading
AIR is a public, social experiment in which people are invited to use Preemptive Media’s portable air monitoring devices to explore their neighborhoods and urban environments for pollution and fossil fuel burning hotspots.
Participants or “carriers” are able to see pollutant levels in their current locations, as well as simultaneously view measurements from the other AIR devices in the network. An on-board GPS unit and digital compass, combined with a database of known pollution sources such as power plants and heavy industries, allow carriers to see their distance from polluters as well. The AIR devices regularly transmit data to a central database allowing for real time data visualization on this website. The AIR devices are based on the Arduino platform.
