Wireless Rain and Freeze Irrigation Sensor

Protect your irrigation system from unnecessary watering and freeze damage with this wireless rain and freeze sensor. The device creates a wireless link between the outdoor sensing unit and your irrigation controller, completely removing the need to run a wire from the control panel to the sensor location. A built-in thermistor monitors ambient cold, while integrated water-absorbing disks physically swell when precipitation falls. Either condition automatically signals your system to pause its scheduled watering cycle.

You can adjust the trigger threshold to set precise rainfall requirements before the mechanism initiates a rain delay. The straightforward construction works alongside controllers from Orbit, Hydro-Rain, and other major brands without complex programming or electrical modifications. By automating winter freeze protection and rainy day pauses, this sensor keeps your landscape maintained efficiently while preventing water waste and pipe damage.
