The Capacitive Touch Dimmer Module is a touch-based control module designed to detect finger touch and provide dimming or level-based control output. It uses capacitive sensing technology to replace traditional mechanical switches, offering smooth, silent, and long-life operation. This module is commonly used in touch lamps, LED dimmers, control panels, and DIY electronics projects where touch-controlled intensity adjustment is required.
