The Benefits of Rain & Freeze Sensors

A sprinkler system weather sensor is designed to reduce water waste by preventing your sprinklers from running unnecessarily after it rains or in the cold. This can lead to water conservation and lower utility bills. These sprinkler weather sensors are generally compatible with most sprinkler controllers. They work by connecting to the controller and overriding the schedule when it starts to rain or when the temperature drops. By understanding how rain and freeze sensors work and how to maintain them, you can better protect your sprinkler system and optimize water usage.

Rain & Freeze Sensor FAQs

Where should I install a rain sensor? Where should I install a freeze sensor?

Install a rain sensor in an open, unobstructed area, typically on the roof, a fence, or a pole where it will be exposed to rainfall. Avoid installing it under trees, overhangs, or areas where it may be covered from the rain. Freeze sensors should similarly be installed where they are exposed to the outside air. Make sure to move them away from direct heat sources like vents, which might give a false reading.

Why do I need a freeze sensor for my sprinklers?

A freeze sensor protects your irrigation system from potential damage caused by freezing temperatures, which can lead to cracked pipes or broken sprinkler heads. Additionally, watering in freezing conditions can create dangerous ice on driveways and sidewalks.

Do I need a rain sensor if I have a smart controller?

Many smart controllers use weather data to automatically adjust their watering based on local rain forecasts. However, a physical rain sensor adds a layer of real-time protection, especially in case the weather data is inaccurate or internet connectivity is lost. A sprinkler rain sensor ensures your system responds to actual rainfall.
