Irrigation Sensors

Take your irrigation system from simply “on a schedule” to smart and responsive. In our Irrigation Sensors collection you’ll find devices that provide real-time data, helping your system water only when needed—avoiding waste, runoff and stressed plants.

Sensors like rain shut-off, soil-moisture probes, flow & pressure meters, freeze sensors and more allow you to monitor key conditions in your landscape. For instance, a rain sensor stops irrigation when sufficient rainfall has occurred. Soil-moisture sensors detect moisture levels in the root-zone and override fixed timers when the ground is still wet. Flow sensors monitor water movement through your system, alerting you to leaks or blockages.

In this collection you’ll find:

• Rain sensors that mount outdoors to prevent irrigation after storm events. 

• Soil-moisture and temperature sensors that measure root-zone conditions for smarter watering.

• Flow, pressure and system-health sensors that help you detect inefficiencies or system faults early.

• Sensors compatible with DIY systems, homeowner setups and pro irrigation systems—so whether you’re doing a home lawn or a large landscape you’re covered.
