Rainbird Wireless Rain and Freeze Sensor System with 1 Controller Interface and 1 Sensor

Rainbird’s Wireless Rain and Freeze Sensor System combines a rain sensor and a freeze sensor with a simple controller interface, giving homeowners precise control over irrigation. When rain is detected, the sensor automatically shuts off watering, while the freeze sensor stops irrigation if temperatures dip below a programmable threshold, protecting vulnerable plants.
The system can reduce water use by up to 35%, thanks to adjustable rainfall settings from 1/8 to 1/2 inch and temperature limits between 33°F and 41°F. Its enhanced antenna array delivers reliable signals even with line‑of‑sight obstacles, and the icon‑driven interface makes programming intuitive.
Compatible with most 24VAC controllers, it offers a versatile, plug‑and‑play solution for both Rain Bird and competing brands.

FAQs
What key features should I prioritize when selecting a Rain Bird wireless rain sensor?
Look for sensor accuracy, wireless range, battery life, and compatibility with your existing controller. A reliable sensor will detect light rain and shut off irrigation promptly, saving water. Also consider weather resistance ratings to ensure durability in harsh conditions.
How does the Rain Bird 5000 Series compare to the 4000 Series?
The 5000 Series offers a longer wireless range (up to 500 ft) and a larger rain‑catching cup, which improves detection of light precipitation. The 4000 Series is more compact and slightly cheaper, making it ideal for smaller yards. Both models share the same easy‑install mounting hardware.
Is the wireless range sufficient for large properties?
Yes, the 5000 Series can reliably communicate up to 500 feet line‑of‑sight, and the 4000 Series covers up to 300 feet. For very large or obstructed sites, you may need a repeater or multiple sensors to maintain signal strength. Check your layout for walls or dense foliage that could block the signal.
What are the battery requirements and expected lifespan?
Both models use a standard AA alkaline battery, lasting 12‑18 months under typical use. Some versions support a rechargeable lithium‑ion pack for longer service intervals. Battery status is indicated by a LED blink pattern on the sensor housing.
Can the sensor integrate with any irrigation controller?
Rain Bird sensors are designed to work with most Rain Bird controllers that have a rain sensor input, but they also include a universal 24‑V AC output for third‑party systems. Ensure your controller supports a dry‑contact or voltage‑triggered input. Installation guides provide wiring diagrams for both native and universal setups.
Are there durability differences between the models?
Both sensors meet an IP66 rating, protecting against dust and heavy rain, but the 5000 Series features a reinforced housing with UV‑stabilized plastic for added longevity. The 4000 Series, while still robust, uses a slightly thinner shell that may be more prone to impact damage. In extreme climates, the 5000 Series is the safer choice.
What overall value do Rain Bird wireless rain sensors provide?
Rain Bird sensors deliver measurable water savings—often 10‑20%—by preventing irrigation during rain events, which translates to lower utility bills. The 5000 Series commands a higher price but offers greater range and durability, making it a better long‑term investment for larger properties. For modest budgets and smaller lawns, the 4000 Series provides solid performance at a lower cost.
