Air monitor of the future?

Intel Labs in Berkeley, Calif., recently showed off a prototype air quality monitor that could one day be embedded in smartphones. The idea is to create relatively cheap monitors that get very localized data and transmit it to a central point for analysis, a system that could be more accurate than existing monitors. This device, about the size of a cell phone, can gather data on nitrous oxide, carbon monoxide, and ozone, according to Intel.
