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

Proven Water Saver

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.
