Hunter Wireless Rain-Clik Rain Sensor


The first reliable wireless rain sensor provides fast installation on any system. Like the traditional Hunter Rain-Clik this sensor provides instant shut off to a system in the event of rainfall. But has the added feature of being wireless from the controller to the sensor allowing for simple installation.



Most rain-sensing devices work by accumulating a set amount of rainfall before a switch is activated that interrupts the circuit from the controller and shuts off the system. In that “accumulation time”, the system will unnecessarily continue to water. This can look especially bad for conservation-conscious municipalities, businesses, and residences. With built-in Quick Response technology, the Hunter Rain-Clik and Wireless Rain-Clik can command a controller to shut off right when it starts to rain. The Rain-Clik can be mounted on an eave or any flat vertical surface like a wall or fence. A gutter mount is also available that allows for easy installation of the Rain-Clik on the edge of a gutter.
