Metal Touch Sensor Module

Product details The Metal Touch Sensor Module is designed to detect human-touch input through direct contact with a metal surface. It functions on the principle of capacitive sensing, where body capacitance triggers a signal change when a finger touches the metal pad. The module incorporates a sensitive touch-detection IC and onboard signal conditioning for stable operation even in environments with electrical noise. The module provides a clean digital output  that can directly interface with microcontrollers such as Arduino, ESP32, Raspberry Pi, and other embedded systems. An onboard indicator LED provides visual confirmation of touch activation. Its compact size, low-power consumption, and consistent response make it suitable for touch-based switching, security systems, and smart interactive designs where mechanical switches are undesirable.
