Today we review PhD research from Germany that describes how a commercial off-the-shelf (COTS)dust sensor can be attached to a smart phone, making use of its camera to measure the scattering of light and estimate the concentration of particulate matter (PM10) with an accuracy of one microgram per cubic meter. Readings may then be transmitted via cell phone to a central point where a number of other phone measurements can be mapped in near real-time and add to the more sophisticated (and expensive) observations from the few government air quality stations.
