MT10 SDI-12 Output Soil Temperature And Moisture Sensor

MT10 SDI-12 Output Soil Temperature And Moisture Sensor

The MT-10 sensor uses an electromagnetic field to measure the dielectric permittivity of the surrounding medium. The sensor supplies a 70 MHz oscillating wave to the sensor prongs that charges according to the dielectric of the material. The stored charge is proportional to soil dielectric and soil volumetric water content. The MT-10 microprocessor measures the charge and outputs a value of dielectric permittivity from the sensor.

 About MT-10

We designed the MT-10 to measure the water content, electrical conductivity, and temperature of soil. The MT-10 uses an oscillator running at 70 MHz to measure the dielectric permittivity of soil to determine the water content. A thermistor in thermal contact with the sensor prongs provides the soil temperature. The Polyurethane coating on the MT-10 circuit board protects the components from water damage and gives the sensor a longer life span.
