The Belkin F5Z0340FCAPL WeMo Switch and WeMo Motion Kit gives you wireless control of your home appliances and electronics, turning devices of your choice on or off as soon as movement is detected. The sensor plugs into an outlet and detects motion up to 10 feet away. It then sends a wireless signal to the WeMo Switch to turn the connected device either on or off. Download the free WeMo app to any Apple device (iOS 5 or higher) to program a light to turn on when you walk into the house or a fan to turn off when you leave. Just place the WeMo Motion sensor wherever you like, connect it to a WeMo Switch controlling a light, and that light goes on whenever you pass by. Device Compatibility: iPad 2, iPhone 4, iPod Touch, iPhone 3GS, iPhone 4S, iPad 3, iPad.
