Toro Co.: Precision Soil Sensor

December 26, 2012 -  By

The new 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: a receiver that hooks up to the irrigation controller, and a sensor that installs in the ground. Once installed, the sensor calibrates itself automatically to determine the soil type. Any time the moisture level exceeds the user-defined optimum level for the plant material, the controller is prevented from running any irrigation programs. This prevents unneeded watering and provides the possibility for significant water savings. Wireless communication between the sensor probe and the receiver has an operating range of up to 500 ft. Installation requires no digging, so the soil is left undisturbed, allowing the sensor to take accurate moisture readings starting as soon as it’s put in the ground. The unit is also the first soil sensor to offer freeze detection, which prevents irrigation when temperatures approach freezing.
