Toro Precision Soil Sensor Sell Sheet
Precision™ Soil Sensor
Sensors
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.
Prevents 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 a 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.
Precision™ Soil Sensor
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 as “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).

Operating Specifications and Additional Features
• Sensor receiver hooks up to irrigation controller’s sensor port
(if available) or is wired into common wire
• Up to 500’ (152m) range, line of sight
• One sensor per receiver
• Adjustable moisture threshold in 1% increments allows the user
to set the desired moisture level
• Sensor automatically determines soil type and adjusts
calculations accordingly
• Freeze detection prevents irrigation when temperatures
approach freezing
• Smart bypass overrides the sensor for a user-defined length of
time (especially useful during system winterization)
• If the sensor is tripped while the irrigation controller is in
the middle of a watering program, the optional “Cycle Delay”
feature ensures all subsequent zones in the irrigation program
have a chance to get watered before the sensor halts watering
• Multi-color LED on the sensor probe indicates radio
signal strength
• Sensor probe’s ultra-slim ¾” profile allows it to avoid being
damaged by mowing equipment
• Extra long stainless-steel electrodes measure over 4 inches
down into the soil profile
• Sensor probe’s support stakes hold sensor firmly in place
when installed
• Easily replaceable batteries last up to 2 years with alkaline
batteries (longer with lithium)
Warranty
• Two years
