- IG Soil Moisture Sensor – SD-12 Interface



GroPoint TDT technology and is accurate, reliable and robust. The small, sleek light weight design is extremely easy to install. When installed vertically, the sensor averages volumetric moisture content over a soil layer of about 8' (21cm). When installed horizontally, the sensor can be used to measure moisture at a specific soil depth. The moisture sensor is attached to a 3.3 feet (1 meter) cable, with lengths up to 500' available upon request.

This highly accurate GroPoint Lite Moisture Sensor provides cost effective soil moisture measurement. GroPoint Lite can be deployed in irrigation sensitive zones, such as around the root zone, to enable full control of precision irrigation needs. Moisture measurement is used in applications such as turfgrass, high-value agriculture crops to better manage irrigation practices, increase plant and turf quality and reduce fertilizer run-off. GroPoint Moisture Sensors have a high level output signal for direct interface to a variety of control, datalogging, and telemetry systems.
