ABSTRACT:
A moisture sensing circuit for a clothes dryer in which clothes tumble during drying has a pair of spaced apart electrode sensors for sensing the electrical resistance of the clothes when the clothes contact the electrodes. The circuit has an active filter for suppressing noise related to the operating line frequency of the clothes dryer to provide a filtered voltage signal representative of voltage drop across the electrode sensors with the line frequency noise suppressed.
