Orbit 57069N Rain and Freeze Sensor
The Orbit 57069N combines rainfall and low-temperature detection to protect irrigation schedules from wasting water. It uses weather-resistant wiring from the controller to an outdoor location and features water-absorbing disks that expand when damp, signaling the controller to suspend watering. This sensor is suitable for lawns and gardens with exposed irrigation equipment and provides a straightforward fix for stormy or cold conditions.
Rain Bird CPRSDBEX Wired Rain Sensor
The Rain Bird CPRSDBEX is a wired rain sensor with an adjustable rainfall dial and a mounting bracket. It automatically shuts off and restarts the sprinkler system when rain is detected, helping conserve water and reduce runoff. Its adjustable rainfall settings range from 1/8 inch to 3/4 inch, and a side vent ring helps the sensor dry out after exposure to moisture.
Rain Bird Wireless Rain & Freeze Sensor System
This wireless system includes both a rain sensor and a freeze sensor with a single controller interface. It shuts off irrigation when rain falls or temperatures drop below the preset point, offering potential water savings up to about 35%. The interface is icon-driven for easy programming, with adjustable rain settings from 1/8 to 1/2 inch and low-temperature settings from 33 to 41 degrees Fahrenheit. Note compatibility restrictions apply with certain Rain Bird smart controllers.
TNITRIB Rain Sensor Hygroscopic Discs Replacement
This replacement kit offers hygroscopic discs compatible with multiple Rain Bird and Hunter sensors, enabling simple, tool-free maintenance. If a sensor wicking pan has worn out, substituting the discs can restore performance without replacing the entire unit. The kit emphasizes quick, five-minute repairs to extend sensor life and preserve irrigation efficiency.
Hunter Sprinkler MINICLIK Rain Sensor
The Hunter MINICLIK Rain Sensor is designed for quick installation on most automatic irrigation systems. It stops scheduled irrigation once rain exceeds a pre-set threshold and resumes after the storm ends. Its compact design and straightforward operation make it a popular choice for homeowners seeking a simple, reliable rain sensor solution.
Hunter Sprinkler RAINCLIK Rain-Clik Sensor
The Rain-Clik Sensor by Hunter features built-in Quick Response technology to shut off a controller as soon as rain begins. It can be mounted on an eave, wall, or fence, with an optional gutter mount for edge installation. This setup helps protect gardens and soil from overwatering during wet periods, aligning with efficient irrigation management.
Irritrol RS1000 Wireless Rain Sensor
The Irritrol RS1000 provides constant transmitter-receiver communication to reflect the sensor’s wet or dry status, even after a power outage. It offers versatile mounting options with quick-clip gutter brackets and conduit adapters included. A signal strength indicator helps ensure proper installation and reliable wireless performance for irrigation systems.
Buying Guide: Key Purchase Considerations
- Wired vs. wireless: Choose based on existing wiring and ease of installation. Wireless options reduce cabling but require clear line-of-sight or robust signal.
- Rainfall sensitivity: Look for adjustable rain thresholds (e.g., 1/8″ to 1/2″ or 1/8″ to 3/4″). Ensure it matches your local climate and plant needs.
- Freeze protection: If you live in freezing regions, a combined rain and freeze sensor helps prevent damage from cold weather.
- Compatibility: Verify compatibility with your controller brand and model. Some sensors are optimized for specific controllers and may not work with all systems.
- Installation options: Check mounting flexibility (eave, wall, gutter, or conduit). Consider if you need quick-connect brackets or tool-free repairs.
- Maintenance: Some units offer easy replacement parts (wicks or discs) to extend sensor life without full replacements.
- Reliability: Wireless models should provide stable signal strength and a clear status update to the controller, especially after outages or power interruptions.
- Maintenance horizon: Consider how weather exposure and debris may affect sensors and whether venting or drying features are included to prevent false readings.
