Determine fruit ripeness with your phone

The mobile phone could be used to determine how ripe your fruit is thanks to new technology

Your mobile phone may soon be able to tell you if that watermelon is ripe. Scientists at the Fraunhofer Institute for Photonic Microsystems and the Technical University in Dresden designed a tiny spectrometer–a near infrared (NIR) apparatus that could let consumers know if the food is over-ripe or rotting. The spectrometer analyses light and what substances are present in gases and liquids, so the gas exuded by fruit would determine how ripe it is. A report said that a phone with the spectrometer could be held next to a product and results would be interpreted with an app. Other uses for the device could be measuring blood sugar levels in diabetics.
