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 system, reducing wasteful over-watering, while promoting
the overall health and beauty of your landscape.
The Precision 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 suitable lawn
area where it sends soil moisture and air temperature readings to the
receiver every 10 minutes. When automatic watering is scheduled to
start, the Precision system 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 Precision 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 system, 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.
