An ice detector includes a pair of electrodes connected by a pair of leads to a control unit which measures the admittance between leads to thereby sense and detect the presence of ice and other contaminants formed on top thereof utilizing a detection circuit. The electrodes are integrated into patch which can be placed at different locations on an aircraft.
