Hunter Wired Mini-Clik Rain Sensor — 25 ft Wire, Mechanical Tipping Rain Shutoff for Irrigation

Hunter's Wired Mini-Clik Rain Sensor automatically pauses your sprinkler schedule when preset rainfall occurs, preventing overwatering and conserving water.

Installed on an irrigation system, the Mini-Clik senses accumulated rain and opens the controller circuit so scheduled zones stay off until conditions dry. Designed for simple wiring and broad compatibility, this compact sensor works with Hunter controllers and most other brands to keep landscapes healthy and water use efficient without constant monitoring.

How does the Mini-Clik detect rain and stop irrigation?

The Mini-Clik uses a mechanical tipping-style sensor calibrated to trigger when a specific depth of rainfall accumulates. When that threshold is reached, the sensor opens the valve circuit to prevent scheduled irrigation from starting or continuing. After the rain clears and the sensor dries, the controller circuit closes and normal watering resumes.

• Factory-set rainfall trigger between 1/8" and 3/4" depending on model calibration
• Mechanical tipping cup design for reliable accumulation measurement
• Automatic reset once sensor dries—no manual intervention required

Will the sensor work with my existing irrigation controller?

Yes—the Wired Mini-Clik is engineered to be compatible with all Hunter controllers and with most third-party irrigation controllers that accept a simple rain-sensor switch. It installs as an inline dry-contact sensor in the controller’s sensor terminals, making integration straightforward for most systems.

• Uses a two-conductor dry-contact interface compatible with standard sensor inputs
• Includes 25 feet of 20 AWG UL-approved sheathed wire for easy hookup
• Works with industry-standard sensor terminals—no special adapters required

How durable and low-maintenance is the Mini-Clik outdoors?

The sensor is built for real-world yard conditions and includes debris-resistant components to keep it operating reliably in variable weather. Its compact, sealed housing minimizes exposure to dust and insects, and the mechanical tipping mechanism requires little to no maintenance beyond occasional inspections.

• Debris-tolerant design reduces false trips and sticking
• Weatherproof casing suitable for outdoor mounting
• Simple occasional checks are usually sufficient—no batteries or complex service required

What installation details should I know before buying?

Installation is straightforward for anyone familiar with basic irrigation wiring. The Mini-Clik mounts on a post or structure in an open area where it can freely collect rain and includes 25' of pre-attached sheathed wire to reach most controllers or sensor junction points.

• Supplied 25' 20 AWG two-conductor UL-approved wire for immediate hookup
• Mounting hardware and simple instructions make placement quick
• Position away from sprinkler spray and heavy eaves for accurate rainfall measurement

Who this is for: The Hunter Wired Mini-Clik is ideal for homeowners, landscape contractors, and property managers who want a no-fuss, reliable rain shutoff that reduces water waste and protects plantings. It suits existing irrigation systems where automatic prevention of needless watering is desired—especially for those seeking compatibility with Hunter or common third-party controllers and a low-maintenance sensor that simply works in everyday outdoor conditions.
