The Touch Sensor Switch Module is a compact touch detection board that works like a digital button. It detects touch or tap input and provides a digital output signal that can be used to control LEDs, relays, buzzers, and microcontroller-based projects. This module is widely used in touch-operated switches, smart home panels, interactive DIY builds, and automation systems where a modern touch interface is required.
