A group of researchers at the VIT Technical Research Centre in Finland have developed a miniature phone sensor that is capable of using light to identify the type amount of various kinds of gases in air samples.

The phone sensor works by shining light of various wavelengths. Different gases absorb wavelengths at known rates, making it possible to ascertain the properties of present gases.

While we're already quite familiar with the workings of smartphones that are able to monitor things like light, sound, movement and geographical location, the use of smartphones to monitor airborne gases sounds like something out of science fiction -- but the technology is on its way to being realized, at which time it is sure to generate all kinds of commercial interest.
