The Hunter Miniclik Rain Shut-Off Sensor is the most effective way to prevent sprinklers from coming on during or after rain. It easily installs on any automatic irrigation system, then shuts sprinklers off when raining and keeps them off, automatically compensating for the amount of rainfall that occurred.
Discs absorb water and expand proportionally to the amount of rain that fell. As the moisture-laden discs expand, they eventually activate a switch that interrupts the circuit from the controller to the solenoid valves. Once dry, they contract and release the switch. Thus, Mini-Clik automatically resets without ever affecting your controller.

There's no better way to ensure that a system isn't watering when it isn't necessary.
