Using an iPhone, sensor chip and programming, a NASA scientist creates a limited tricorder to sense trace amounts of certain gasses.
Jing Li and his team at NASA’s Ames Research Center in Moffet Field, California, used a silicon-sensing chip in micro-board with sixty-four nanosectors.
The device can detect even trace amounts of ammonia, methane and chlorine gas in the air. It can communicate the results to other iPhone or to a computer.
