Toro Plastic Moisture Sensor 1 pk

The Toro Precision Soil Sensor continuously measures moisture levels in the soil and determines when to allow the irrigation controller to water, maximizing the efficiency of your irrigation system. There are two: wireless components to the system- a receiver that hooks up to the irrigation controller, and a sensor that installs in the ground. Any time the moisture level exceeds the user-defined optimum level for the plant material, the controller is prevented from running any irrigation programs.
