TOUCH_SENSOR

Published:2009/7/14 19:55:00 Author:May | From:SeekIC

This circuit is a basic two-contact touch-switch sensor circuit. The negative input (pin 6) of IC1 is tied to the positive supply through R2 (which is actually two 22-MΩ resistors connected in series), while the positive input (pin 7) is connected through R1 (made up of two 22-MΩ and one 10-M.Ω resistor in series).
