MT10 soil temperature and moisture sensor for SDI-12 output
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.
