A moisture sensor for an agricultural combine comprises a chamber having an inlet and an outlet and a paddle wheel flow controller located adjacent to the outlet. The paddle wheel flow controller is rotated by an electric motor which is controlled by an electronic controller. Grain from the clean grain elevator is directed through the inlet of the chamber past a capacitance sensor comprising a first, second and third plates. By measuring the capacitance of the grain, the moisture in the grain can be determined.
