ABSTRACT:
A moisture sensor for detecting the moisture in a particulate material, the moisture sensor comprising a capacitance sensing probe having a first part with a dielectric coating and a second part, the second part being electrically conductive, physically isolated from the first part and disposed to be in electrical contact with the particulate material, and a capacitance detector connected to the first part and the second part, the capacitance detector being configured to generate an electrical signal dependant on the capacitance of the capacitance sensing probe. Soil moisture is measured by change in capacitance of the capacitance sensing probe.
