Soil Moisture Sensor Product Description

AT210 Soil Moisture Sensor provides reliable and accurate soil moisture monitoring for applications including:

Bioremediation
Wastewater Reclamation
Landfill Management
Agriculture
Water is the primary factor in determining the dielectic constant of soil. Global Water's Soil Moisture sensor measures the dielectric constant of the soil, which is directly related to the water content of the soil. The sensor uses TDR, time domain reflectometry, for direct soil moisture measurement.

When installed vertically, the moisture sensor can be used to average moisture readings along a soil column. When installed horizontally, the sensor can be used to measure moisture at a specific soil depth.

The Soil Moisture Sensor has a high level output signal for direct interface to a variety of control, datalogging, and emetry systems. Global Water offers remote monitoring and control products with exceptional capabilities. In addition, Temperature Sensor can used in conjunction with the Soil Moisture Sensor to enhance systems monitoring plant growth and controlling bioremediation.
