Soil Moisture Sensors
EC-5/10HS/5TE/5TM/GS3
Preparation:
The ECH2O EC-5, 10HS, 5TE, 5TM, and GS3 can all be installed using the same installation method.Inspect and verify sensor components. When using the sensors in lightning-prone areas, follow the directions for providing protection for the sensors found in the application note Lightning surge and grounding practices.
Testing Sensors:
Take some measurements with the sensor using a data logger. Keep in mind that sensors will not necessarily read 100% VWC in water and 0% in air. The sensors are optimized to read soils, and the factory mineral calibration is done in real soils, not air and water. It is important to check the sensor functionality in air and water (see Functionallity in air and water table). Values are given in % VWC using the factory mineral soils calibration. Sensor values vary less than 1% from one sensor to the next.
Field Installation:
Proper installation of the sensors is critical for proper operation. The recommended technique is outlined below. Please read the complete user manuals.
