Gen3 Soil Moisture Sensor measures soil water tension (matric potential) and temperature. With a resistive granular matrix element, you can optimize your tension parameters to determine the earliest indication of water stress and make sure you irrigate before it reaches that point. The unique element feature delivers consistent calibration without needing to recalibrate for every installation. The Sensor also has a thermistor-based temperature element. Its readings will help you assess temperature -40°C to 125°C (-40°F to 257°F) and the moisture’s temperature compensation, eliminating the need to measure moisture every time the soil temperature changes.
