GroPoint Lite!

TECHNICAL INFORMATION

The GroPoint Lite soil sensor is robust, reliable and highly
accurate, providing cost effective soil moisture and
temperature measurements. The sleek light weight design
installs quickly with minimal soil disruption. When installed
vertically, the sensor averages volumetric moisture
content over a soil layer of about 6” (15cm). When installed
horizontally, the sensor can be used to measure moisture
at a specific soil depth.

Wiring Legend!

0-5mA and 4-20mA

Note that the analog GroPoint Lite also includes a green cable, but it should not be
connected in an installation. It is used only for calibration and testing.
