Meet the Voltaire Grinder: a WiFi connected device with sensors to measure the freshness of your beans and alert you when you need to order more. It comes with an app that lets you access fineness, grind time, volume throughput and other info on your smartphone. The platform takes into account volatile compound release, gas concentration, temperature, humidity, bean mass, and volume to tell you more about the freshness level of your beans.
Voltaire comes with a locking led, LED timer, illuminated catch, and a battery pack. It has a portable design. The project is on Kickstarter at this time.
