The Droplet Robotics Sprinkler works with your home's WiFi network and can be controlled from afar using your phone. It broadcasts a wide stream of water for a lawn, but you can also program the device to water select plants and trees, eliminating water waste. Additionally, it knows the local weather and cancels planned waterings if it's about to storm. [$300; smartdroplet.com]
