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.

Why shop with Big Frog Supply? Because we understand irrigation, plumbing and lighting—and we know sensors aren’t just “extras,” they’re performance tools. We bring you sensor equipment, clear specs and real-world help to ensure you select the right device for your system size, environment and budget.

Pro tip: Install your sensor in a representative location—e.g., a soil-moisture sensor in the root-zone of the typical plant type, a rain sensor in an open area away from overhangs—and configure the threshold settings according to your site conditions. Regularly check sensor wiring, cleaning and calibration. A good sensor can save significant water and protect your landscape long-term.
