The Sercomm SZ-WTD03 water sensor has a futuristic design, compact size, and a wide variety of additional functions. The sensor will alert you to the presence of water prior to major damage being done, all while being maintenance-free without the need for professional installation. The sensor also has the ability to be installed as a water bug without wires or mounted higher on a wall and use a probe near the floor to preserve the sensor in the case of high water.
