Hunter Mini-Clik Rain Sensors
A Proven Water Saver

The world’s most simple, accurate, rugged, and reliable rain sensors.


There’s nothing more embarrassing–or more wasteful or costly–than an irrigation system that runs when it doesn’t have to…in the rain. Mini-Clik® provides the simplest, most effective way to prevent sprinklers from coming on during or after precipitation. It easily installs on any automatic irrigation system, then shuts sprinklers off in a storm and keeps them off, automatically compensating for the amount of rainfall that occurred. Disks absorb water and expand proportionally to the amount of rain that fell (e.g., a small cloudburst would result in little absorption, a 6" thunderstorm would lead to more absorption and expansion). As the moisture-laden disks expand, they eventually activate a switch that interrupts the circuit from the controller to the solenoid valves. Once dry, they contract and release the switch. Thus, Mini-Clik automatically resets without ever affecting your controller. There’s no better way to ensure that a system isn’t watering when it isn’t necessary.
