The average human nose might not be able to accurately predict its freshness by smell alone, but modern technology can. That’s the claim behind [PERES](https://www.indiegogo.com/projects/peres-smart-way-to-protect-you-from-food-poisoning "undefined"), a handheld [smartphone accessory](http://www.techlicious.com/phone-accessories/ "undefined") for your kitchen that sniffs meat to detect spoilage. Specifically, PERES measures four things: Temperature, humidity, ammonia, and volatile organic compounds VOCs. It uses this data to detect whether meat is fresh and safe to eat. The device connects to your Android or iOS smartphone via [Bluetooth](http://www.techlicious.com/blog/new-devices-go-low-power-with-bluetooth-4.0/ "undefined"), and works with most common types of meat – beef, poultry, pork and fish. PERES is being offered through crowd-funding site IndieGogo, where it has already surpassed its $50,000 goal. The device is scheduled to enter mass production in October 2014 with an expected retail price of $150.
