TTP223 Blue Touch Sensor Module
The TTP223 Blue Touch Sensor Module is a compact capacitive touch switch designed to replace traditional mechanical push buttons. Based on the TTP223 touch-sensing IC, it detects the touch of a finger and provides a digital output signal, making it ideal for Arduino, Raspberry Pi, ESP8266, ESP32, and other microcontroller-based projects. The module offers reliable touch detection through non-metallic surfaces such as plastic, glass, acrylic, and thin wood, enabling sleek and modern user interfaces.
