Dryness control for clothes dryer

A dryness control circuit for a household clothes dryer including a power supply circuit and a moisture sensing circuit. The power supply circuit converts high voltage AC power into low voltage, DC power. The low voltage, DC power is supplied to the moisture sensing circuit. The moisture sensing circuit includes a moisture sensor having a pair of spaced-apart electrodes, a time delay circuit, an electrostatic discharge attenuation circuit, and a motor controller circuit. The motor controller circuit includes a control hysteresis or dead-band in which operation of a timer motor is unaffected. The time delay circuit includes an RC network which slowly charges and discharges to prevent erroneous dryness or moisture readings, which are sensed by the moisture sensor, from causing the motor controller circuit to improperly actuate or deactuate the timer motor. The electrostatic discharge attenuation circuit negates the deleterious effects of static build up. The time delay and control hysteresis of the moisture control circuit cooperate to prevent false actuation or deactuation of the timer motor.
