Abstract

PURPOSE: To ensure the detecting operations by subjecting an excitable circuit for exciting the quartz oscillator of a sensor to frequency sweep to detect the variation in the amplitude of the output signals of the sensor so that the signal indicative of the dew formation may be produced with the use of the detected signals.
