This article describes what an irrigation rain sensor is and when one should be used.
What is an irrigation Rain Sensor?
A rain sensor is simply a switching mechanism activated by rainfall. The device is connected directly or indirectly to a controller which operates an automatic sprinkler system. There are several rain sensor devices on the market but they all share the same purpose and that is to mitigate water usage by preventing an automatic irrigation system to run while it is raining. Most rain sensors will also keep the system shut off for a duration after the rain has stopped. In most cases the system will not shut down until enough rain water is absorbed by the rain sensor or until the moisture is significant enough to trigger the switch to shut down the system.
