'E-Nose' in the Works to Detect Food Spoilage

Is that meat safe to eat? The Peres device is designed to give exactly that information. It samples the air around the raw meat in question and sends it to a smartphone to be analyzed and relayed to the user. Data can also be shared via social media.

Peres, the electronic "E-nose," is a gadget up for crowdfunding on IndieGoGo. The device samples air around meat by detecting the concentration of volatile organic compounds and transmits the data to a smartphone or tablet for calculation. Users can view results for a decision on whether to eat it or not. The information can also be posted to social networks.
