Automatic Rain and Freeze Sensor for Sprinklers

This automatic rain and freeze sensor protects your irrigation system from unnecessary watering by halting cycle operation whenever precipitation occurs or temperatures approach freezing. Connecting directly to your controller’s dedicated port through a simple plug-and-play design, it works with major brands like Orbit and Hydro-Rain without requiring system replacements.

A weather-resistant wire runs up to thirty feet from the control box, allowing flexible outdoor placement away from direct spray impact. Water-absorbing disks detect active precipitation, while a built-in thermistor prevents watering when ambient conditions cross temperature thresholds. Adjustable sensitivity matches regional rainfall rates, and the hardware automatically resumes programmed schedules once dry weather returns.
