The BeerBug

This one goes out to all my brewing friends that may want to keep tabs on their home brew operations even if they're not home with the BeerBug ($250). This WiFi-enabled sensor monitors the specific gravity, temperature, and alcohol content of your brew,  it even lets you view real-time data via a web browser or through 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. Happy Brewing! If you want more information on this product it can be found here.
