I-SPEX: use your iPhone to measure the pollution in the air

I thought smart phones where mostly social tools. “I-SPEX” (Spectropolarimeter for Planetary EXploration) turns your iPhone into a scientific instrument. SPEX enhances the lens of the iPhone in such a way that you can measure the pollution in the air: especially PM (Particulate Matter). Developer and scientist Frans Snik’s first goal is to use it in the biggest Dutch citizen science experiment: 10000 people will measure the local air on the same day. The info can be used to map air pollution and hopefully help to do something about it.
