Soil Sensor System
User’s Guide
Introduction
Leveraging the same Toro soil-sensing technology used on high-end
commercial sites and world-class golf courses, the Toro Precision
™
Soil
Sensor continuously monitors the soil moisture and determines when
watering is actually needed – greatly increasing the efciency of your
sprinkler , reducing wasteful over-watering, while promoting the over-
all health and beauty of your landscape.
The Precision Soil Sensor system consists of a wireless soil moisture
sensor and digital receiver, making installation quick and simple. The
compact receiver installs alongside the timer, either indoors or out, and
connects directly to the timer’s power and sensor terminals, or simply
taps into the valve common wire circuit. The sensor is placed in a suit-
able lawn area where it sends soil moisture and air temperature read-
ings to the receiver every 10 minutes. When automatic watering is
scheduled to start, the Precision Soil Sensor allows the sprinklers to
run only if the soil moisture has dropped below the minimum moisture
setting, and the air temperature is favorable for watering.
The sensor simply plugs into the soil – so there’s no holes to dig or
wires to bury. All you’ll need to complete the installation is a small
Phillips screwdriver, three AA alkaline batteries and a bit of
do-it-yourself enthusiasm.
The Precision Soil Sensor system is designed to help grow and maintain healthy landscape vegetation while reducing water
use by improving the operation of your sprinkler control timer. It cannot improve or remedy a sprinkler system that’s improperly
designed, installed or maintained. So, to gain the maximum benefit afforded by the addition of the Precision Soil Sensor, it is
vitally important to make certain your automatic sprinkler system is in good working order; capable of providing proper sprinkler
coverage–where and when it’s needed.
