Hunter Mini-Clik Rain Sensor

Description Hunter Mini-Clik Rain Sensor Automatic Rain Shut-Off for Any Irrigation System The Hunter Mini-Clik Rain Sensor is one of the most effective ways to prevent unnecessary watering during or after rainfall. Designed for easy integration, it installs on any automatic irrigation system and immediately halts watering when rain is detected — helping you conserve water and protect your landscape. As rain accumulates, internal hygroscopic discs absorb moisture and expand based on the amount of rainfall. Once expanded, they trigger a built-in switch that interrupts the signal from your controller to the solenoid valves. After the discs dry, they contract and release the switch, allowing your irrigation schedule to resume — all without manual resetting or adjustments to your controller. ✅ Key Features Rain Shut-Off AdjustmentEasily set the sensor to stop watering after 3 mm to 19 mm of rainfall. Automatic ResetMoisture-sensitive discs dry and shrink to reactivate the system — no manual resetting required. Universal CompatibilityWorks with virtually all irrigation controllers and systems. Durable & Weather-ResistantBuilt to withstand outdoor conditions for long-lasting performance. Includes 7.6 m of WireFor flexible installation in a variety of locations.
