Product Information
Full details
The HydroSure Mini Click Rain Sensor is an essential tool for eco-conscious gardeners looking to automate water conservation in their irrigation systems. Designed for users of HydroSure Dual and Single Outlet Digital Timers, this device provides a seamless way to suspend watering schedules during rainfall to prevent overwatering and promote healthier plant growth. While it is highly effective at saving water, it requires a compatible HydroSure controller to function, meaning it cannot be used as a standalone unit without the specified timing system.

FAQs
Does this sensor work with other timer brands?
No, the HydroSure Mini Click Rain Sensor is designed exclusively for use with HydroSure Dual and Single Outlet Digital Timers.
Where is the best place to mount the sensor?
Mount it in an open area that is fully exposed to rainfall but is not prone to high vibration or physical impact.
How do I adjust the rainfall sensitivity?
The sensor features an adjustment dial on the unit that allows you to set the amount of rainfall (in millimeters) required to trigger the shut-off mechanism.
Do I need to replace batteries in the sensor?
No, the sensor receives its power directly from the connected HydroSure irrigation timer.
Will the sensor restart my watering automatically?
Yes, once the moisture level in the sensor disks evaporates and returns to dry, it will signal the timer to resume the pre-programmed watering schedule.
Troubleshooting
Irrigation system continues running while raining
Check the connection cable to ensure it is fully seated in the timer port, or adjust the sensitivity setting on the sensor unit.
Sensor triggers even when there is no rain
Clear any organic debris or obstructions from the sensor disks and ensure it is not located in a high-humidity area like a steam vent or under a dripping gutter.

Setup, Compatibility & Care
Installation is straightforward: connect the sensor cable to the dedicated input port on your HydroSure Dual or Single Outlet Digital Timer. Ensure the sensor is installed at a similar height to your garden beds but remains unobstructed. Compatibility is strictly limited to HydroSure Digital Timers. To maintain performance, inspect the sensor disks monthly to ensure they are free from leaves, dirt, or spider webs, as these can trigger false readings. Gently wipe the housing with a damp cloth if it accumulates dust.
