Mobile Sensing. The Robotic Embedded Systems Lab has created a new app for Droids that measures air pollution at a specific location. An iPhone app is coming; but, for now, you need a Droid and at least OS 2.1. Just snap a photo of the sky at your location, crop out the trees and buildings, if any, and send the photo to the lab. By measuring the light obstruction and your location, they can measure the air pollution. This won't do anything for the air you breathe; but, if enough of us create the data, who knows what might happen. Go green. Measure the air.
