Eaton Water Sensor (http://rbi.ims.ca/4927-544). A water sensor is one of the initial components of Eatons’ Home Heartbeat System that monitors home systems and areas of concern to the homeowner using a ZigBee wireless network. The capacitive sensor provides information regarding water leaks or overflow in basements or areas. In addition, the units can be used where a minimum water level needs to be maintained such as pools, gardens or wells. As part of a complete system, if a water leak is detected, the wireless controller actuates a water shut-off valve. Other wireless sensors in the system include an open/closed sensor for doors and windows.
