Rain Sensors

What is a rain sensor?

A rain sensor is a small device wired to the common line on an automatic sprinkler system designed to override the automatic watering cycle when a certain level of rainfall is detected. The shut-off level is usually set at 1/4 inch of rain.

The sensors do not affect the sprinkler system’s overall timing device. Once the collection dish dries out, the automatic timer kicks in.

Benefits of installing a rain sensor

• Cost savings – the sprinkler system shuts off when adequate rainfall is received, thus saving money on water bills.
• System savings – there is less wear and tear on the sprinkler system because it only runs when necessary.
• Lawn protection – reduces potential damage to the lawn caused by over-watering.
