ABSTRACT:
An improved system and method for providing a dielectric monitor which allows the measurement of the dielectric constant of a conductive material. The capability to accurately and efficiently measure the dielectric constant in soil allows the moisture content of the soil to be accurately determined. The preferred embodiment teaches a sensor that has the ability to compensate for some level of variable conductivity. Alternate embodiments are applicable to areas other than soil moisture measurement.
