Rain sensor shutoff for automatic irrigation systems.
Conserve water by automatically interrupting watering cycle during rainfall.
Includes both metric and standard measurements.
Millimetres of rain before disconnecting as well as duration (after rain stops) before connecting again, can be adjusted.
In most installations the sensor acts as a switch to break the circuit to the solenoid on the valves of the irrigation system when it has rained.
This allows the timer to advance as programmed, but keeps the valves from opening the water flow, subsequently causing the sprinklers not to come on at the scheduled time.
Once the rain sensor has dried sufficiently, the switch closes again to allow normal operation of the sprinkler system.
