Abstract

PURPOSE: To ensure the detecting operation by exciting a quartz oscillator of a sensor with the use of a voltage-controlled oscillator and by detecting the variation in the resonant frequency of the quartz oscillator due to dew formation to take out the signals corresponding to the resonant frequency as a dew signal.
