The Conductivity, water content and soil temperature sensor probe (Decagon 5TE) can measure volumetric water content, electrical conductivity, and temperature of soil. The sensor uses an oscillator running at 70 MHz to measure the dielectric permittivity of soil to determine the water content (VWC). A thermistor in thermal contact with the sensor prongs provides the soil temperature, while the screws on the surface of the sensor form a two- sensor electrical array to measure electrical conductivity.
