nasa-091113 If NASA scientists have their way, smart phones like the iPhone will soon double as mobile chemical detectors. With the invention of a postage stamp sized sensor accessory that can plug into the iPhone, this will be much easier for everyone to use without having to carry around an additional attachment.

This tiny sensor was developed for the Department of Homeland Security, which hopes to eventually have this installed in every cellphone, forming a huge chemical alert network wherever people go. Aside from just sensing for what kind of chemicals are in the air, the sensor will also detect chemical concentration, humidity, and temperature. And thanks to the built in GPS tracking in the iPhone, they plan to even be able to pin point the chemical events for research as well as for in case of emergencies.
