Abstract

PURPOSE: To detect impedance precisely while keeping operation for cleaning or preheating by a method wherein a power for heat cleaning and preheating and a signal power for impedance measurement of a humidity sensor element are commonly used.
CONSTITUTION: First and second switches 11, 12 are turned on, a power voltage VH is impressed on both ends of the first electrode 2, a humidity sensor element 1 is heated at about 450°C, thus performing a cleaning operation to burn off dust and oil sticking on the surface of the temperature sensor element. As an output voltage V0, in this case, there is obtainable an output voltage corresponding to an impedance of the humidity sensor element 1.
