The Capacitive Touch Sensor Module is a compact touch-sensitive input module designed for Arduino, ESP32, Raspberry Pi, and other microcontroller projects. It detects a touch or finger contact on the built-in circular sensing area and provides a digital output signal to the connected controller.
The module features a large capacitive touch pad, onboard sensor circuitry, and a simple 3-pin interface (VCC, GND, SIG) for easy connection.
