Hunter MiniClik Rain Sensor for Sprinkler Systems — Compact, Automatic Rain Shutoff, No Batteries

The Hunter MiniClik rain sensor automatically halts scheduled irrigation when a preset amount of rainfall is detected, preventing overwatering and saving water.

Installed on automatic sprinkler controllers, the Hunter MiniClik provides a simple, reliable way to stop irrigation during and immediately after rain events. It senses accumulated rainfall and interrupts the controller's program until moisture levels drop, then restores normal operation. Designed for straightforward mounting and low-maintenance use, this compact sensor helps conserve water, reduce run-off, and protect plants and turf from excess moisture.

How does the MiniClik detect rain and stop my sprinklers?

The MiniClik uses an internal mechanism that measures accumulated rainfall. When the preset threshold is reached, it opens the circuit to the irrigation controller so scheduled zones are skipped. Once the sensor dries below the threshold, the circuit closes and the controller resumes its normal program.

• Preset activation point triggers an electrical open to pause the controller
• Automatically resets after drying—no manual intervention required
• Compatible with most standard automatic irrigation controllers

Where and how do I install the Hunter MiniClik?

Mount the MiniClik in an open area away from roof overhangs and sprinkler spray to accurately capture rainfall. Wiring connects between the controller and zone valve start wires; installation typically involves mounting the sensor, running the wire, and hooking it to the controller per manual. The compact design fits on fences, posts, or dedicated sensor mounts for flexible placement.

• Mount in a clear, rain-exposed location for accurate readings
• Simple two-wire connection to most irrigation controllers
• Small footprint allows mounting on fences, posts, or sensor brackets

What maintenance does the MiniClik require?

Maintenance is minimal: inspect periodically for debris or obstructions and ensure the sensor is positioned to collect rain. If debris accumulates it can be cleaned with water and a soft cloth; there are no batteries to replace. Proper seasonal checks help ensure reliable performance year-round.

• Occasional visual inspection and cleaning keeps sensor accurate
• No batteries—reliant on electrical connection to the controller
• Durable housing resists weather for long service life

Who is this for? The Hunter MiniClik rain sensor is ideal for homeowners, landscapers, and property managers who use automatic irrigation systems and want a low-cost, low-effort way to prevent unnecessary watering during rain. It fits those seeking water savings and plant protection without complex programming or frequent maintenance. If you run scheduled watering and want a hands-off rain shutoff that integrates with standard controllers, the MiniClik is a practical choice.
