NASA Creates a Chemical-Sensing iPhone Application

 - Nov 13, 2009
Jing Li, a scientist at NASA has developed a chemical sensor application for the iPhone. Working within the Department of Homeland Security's Science and Technology Directorate's Cell-All program Li created a stamp-sized device that can attach to an iPhone and detects chemicals.

So far the iPhone chemical sensor application has sniffed out small amounts of chemicals like methane, ammonia, and chlorine gas. The device is cheap and doesn't require a lot of power. Once the detection data is confirmed the phone can send the information on via Wi-Fi.
