A rain sensor is an irrigation shutoff device that prevents an automatic sprinkler system from turning on during and after a rain storm. Rain shut-off sensors are wired to an irrigation system controller and override the scheduled irrigation when a sensor on the shutoff device detects water.

When the collected rainwater has evaporated from the sensor, scheduled irrigations resume. Rain shut-off sensors are simple, economical and useful tools for preventing irrigation that would be wasteful. Rain shut-off sensors work best for short off periods. For extended periods, it is more accurate to have sprinkler timer in the "off" position.
