BeerBug

Keep tabs on your home brew operation even if you're not at home with the BeerBug. This WiFi-enabled sensor monitors the specific gravity, temperature, and alcohol content of your hooch, letting you view real-time data on a computer via a web browser or through dedicated apps for iOS and Android. Its built-in rechargeable battery lasts over 25 days and recharges over a standard Micro USB connection, so even if your fermenting time runs over, all you need is a common charger to stay informed until it's done.
