Simply plug the connection cable into a HydroSure timer with a compatible port to synchronise communications between your rain sensor and timer for clever watering capable of monitoring rainfall and prompting the timer to skip watering on rainy days.

The sensor has internal porous disks that absorb rainfall causing them to expand. This expansion triggers a message sent down the wire connected to the watering timer telling it to skip the next watering cycle. As the disks dry out, the timer returns to its pre-set cycle. For full irrigation control, the sensor is easily adjusted to detect and cancel watering after 3, 6, 12, 19 or 25mm of rain. To adjust, turn the cap from the current setting and engage the stationary pins with the required slot position.

Arrives complete with a 5 Metre length of outdoor-rated cable and the universal mounting bracket allows for flexible installation to a rain gutter or roof. The sensor should be situated in a position where the internal disks are fully unobstructed to rainfall and sunlight conditions and ensure the sensor is not in contact with the spray from the sprinklers or runoff from the roof. Once connected, the sensor feeds power directly from your water timer – no batteries required. Compatible with the HydroSure Dual and Single Outlet Digital Timers.

Manufactured from strong and durable plastic, the maintenance-free design allows for outdoor installation even in harsh conditions (Avoid submerging the unit in water). For ultimate longevity during the winter months store in an undercover shed/garage in an upright position and drain any sitting water.
