The TTP223 Capacitive Touch Sensor Module (Blue) is a compact and highly sensitive touch detection module designed to replace traditional mechanical push buttons. Based on the TTP223 touch sensor IC, it detects human touch through capacitive sensing technology and provides a digital output signal when touched. The module is easy to interface with Arduino, ESP32, Raspberry Pi, STM32, and other microcontroller platforms, making it ideal for interactive electronics, automation, and DIY projects.
Its reliable touch detection, low power consumption, and simple operation make it a popular choice for modern touch-based control systems.
