What is a rain sensor?
A rain sensor (or rain switch) is a device that prevents your automatic system from operating after it rains. It simply acts like a switch and does not allow electricity to go to your remote electric valves after a certain amount of rain falls. They are adjustable from about 1/8” to 1” of rain. These devices are inexpensive and require little or no maintenance. They should be standard for any system.
