Overview
GS1: Ruggedized Low Cost Volumetric Water Content Sensor
The GS1 is a ruggedized version of our basic, no-frills soil moisture sensor. It accurately measures volumetric water content in soil or soilless media. The longer lifetime of the GS1 helps your budget go further. It delivers research-grade accuracy at a price that makes large sensor networks economically practical. Characterize your site with sensors at multiple depths and locations, even on a tight budget. This sensor is built to last longer in the field under warmer, wetter conditions. The epoxy body withstands harsh environments and water intrusion. Two stainless steel needles cut through the soil for better soil-sensor contact and easier installation. Needles are also much more durable than our standard sensor blades. The GS1 is sensitive across the entire water content range. It can be installed in dry desert soils or in very wet peat. Sensitive to small changes in water content anywhere from 0 - 100% VWC. This frequency minimizes salinity and textural effects, making the GS1 accurate in most soil or soilless media. Can be used in a variety of conditions with the factory calibration. Install the GS1, plug it in to the Em50, set the measurement intervals, and start logging data. No programming required.

Use this sensor with DataTrac 3 to quickly and easily store, access and compare soil water content data from a large installation.
The GS1 accepts a wide range of input voltages and has an easy-to-read voltage output. Voltage correlates to soil water content through a simple linear relationship, making this sensor easy to integrate into a wide variety of non-Decagon loggers.
