Being the dew condensation state detection sensor which detects dew condensation

摘要

PROBLEM TO BE SOLVED: To provide a detection sensor of a dew condensation state constituted so as to detect a wide range of the dew condensation state without being short-circuited by water droplets, reduced in the effect of disturbance noise and having good sensitivity.;SOLUTION: At least a pair of electrodes 5 and 5', at least a pair of the conductors 6 and 6' connected to a pair of the respective electrodes 5 and 5' and the polymeric film 7 formed corresponding to a pair of the conductors 6 and 6' are provided on a plate-shaped member 1 for a window. A pair of the conductors 6 and 6' undergoes electrostatic capacitive coupling and a change in the moisture adhesion amount of the polymeric film 7 is detected on the basis of a change in specific dielectric constant to detect the dew condensation state.;COPYRIGHT: (C)2007,JPO&INPIT
