Meet the Knut Water Detector: a smart device that lets you keep an eye on your home and catch water leaks before they cause any major damage. The Knut is a WiFi connected device. Just place your Knut in the area you would like to monitor and use the companion iOS or Android app to get notified.
Knut comes with humidity and temperature sensors and is easy to set up. The device lasts up to 2 years on two standard AA batteries. More information is available on Kickstarter.
