Rain Sensor

Rain Sensor
K-Rain Rain Sensor products turn an irrigation controller into an expert water manager by efficiently suspending watering during rain and/or freeze periods.

After a set amount of rain has fallen and/or freezing temperatures exist (for models with freeze sensor), the sensor will trigger the controller to suspend watering.

Unlike other Rain Sensors on the market, the K-Rain® wireless rain-freeze sensor (model 3208-WRFS) can be paired with multiple K-Rain Pro EX 2.0 Wifi enabled controllers within range, providing an additional value for the end user. The wired rain sensors work with closed circuit timers.
