CAPACITIVE WATER LEAKAGE INSPECTION DEVICE, SENSING A LEAKAGE OF A LIQUID MATERIAL BY USING A CAPACITIVE TOUCH SENSOR IC OR A CAPACITIVE MCU(MACHINE CONTROL UNIT)

摘要

PURPOSE: A capacitive water leakage inspection device is provided to sense even a drop of water and to easily control sensitivity by resistance and a gap.;CONSTITUTION: A capacitive water leakage inspection device comprises a capacitive touch sensor IC(Integrated Circuit)(400), a conductive first pad(410), and a conductive second pad(420). The capacitive touch sensor IC comprises at least a power pin, a ground pin, a synchronization clock pin, a touch sensing pin, and a sensing signal output pin, and outputs leakage signals with the sensing signal output pin according to a result of a comparison with the capacitive signals input through the sensing pin and reference signals. The first pad is electrically connected to the touch sensing pin. The second pad is electrically connected to one of the power pin, the ground pin, and the synchronization clock pin. The first and second pads are formed on a same plane and arranged to be adjacent to each other. A gap of a predetermined size is formed in between the first and second pads.;COPYRIGHT KIPO 2013;[Reference numerals] (110,210) Touch sensor IC; (121) Power supply; (410) First pad; (420) Second pad
