    Abstract: A sensor for measuring the moisture and salinity of a material is disclosed herein. The sensor preferably includes a soil moisture circuit, a soil salinity circuit and a probe structure. The soil moisture circuit includes a high frequency oscillator, a voltage meter and a reference capacitor. The soil salinity circuit includes a low frequency oscillator, a voltage meter and a reference resistor. A third voltage meter allows for voltage outputs to be measured to calculate soil moisture and soil salinity values.
