Soil Moisture Probe System - Works With Most Controllers


Leveraging Toro sensing technology used on high-end commercial sites and world-class golf courses around the globe, the Toro Precision™ Soil Sensor reduces water waste by continuously measuring moisture levels in the soil and determining when to allow your controller to water, maximizing the efficiency of your irrigation system. Communication between the sensor probe and receiver is completely wireless, so installation is quick and easy with no digging required.

Features & Benefits

Works with nearly all irrigation Controllers

Can be installed on any irrigation controller, including competitive models.

Prevent Overwatering 

Continuously measures soil moisture levels and determines when to allow your irrigation controller to water,making sure just the right amount of water is applied.

No digging Required

Communication between the sensor probe and the receiver is completely wireless, with up to 500'
range (line of sight). Installation doesn't disturb the soil, giving you accurate moisture readings
starting as soon as the sensor is put in the ground.

Automatic Calibration

The sensor will automatically detect the soil type and adjust all calculations accordingly

Freeze detection

The only soil sensor to offer freeze detection that prevents irrigation when temperatures approach freezing.

How it works

There are two components to the system - a battery-powered wireless sensor probe and a receiver that wires into any irrigation controller's sensor port.

Once installed, the sensor calculates field capacity for your soil (or the maximum amount of water the soil can hold after excess water has drained away) and sets that at "100%"

Any time the moisture level in the soil exceeds field capacity, the irrigation controller is prevented from watering until the moisture level falls below the level set in the receiver (default is 50% of field capacity, adjustable by the user)
