Abstract
A grain moisture sensor includes a capacitor having at least a pair of capacitor plates positioned within a grain drying bin adjacent the bottom wall and in spaced relation from the peripheral side walls so that grain in the bin fills the space between the plates and passes downwardly between the plates in response to operation of the discharge auger for the bin. The sensor further includes electrical circuitry for measuring the capacitance of the capacitor, calculating the percentage moisture content of the grain and controlling the activation of the discharge auger for removing a uniform layer of grain from the bottom of the bin in response to the percentage moisture content being lowered to a selected amount.
