NASA Turns iPhone Into Chemical Sniffing Device
A NASA scientist has successfully created a hardware accessory that turns an iPhone into a portable Wi-Fi connected chemical sniffer, capable of detecting small amounts of things like ammonia, chlorine gas and methane. The hardware add-on contains a chip with 16 nanosensors that detect particles from different vaporous substances, then transmitting that information on to the iPhone.
The gadget was created by NASA’s Jing Li, a physical scientist at NASA’s Ames Research Center in California. As part of the Homeland Security’s Cell-All program, he is developing the proof of concept for a system to bring sensors like this one to everyday people to let them know if there has been a chemical accident or attack.
