TTP223 Touch Switch Module

The TTP223 Touch Switch Module is a compact and reliable capacitive touch sensor that allows users to add touch-sensitive controls to electronic projects. Unlike traditional push buttons, the TTP223 detects the presence of a finger through capacitive sensing technology, providing a modern and durable touch interface.

The module generates a digital HIGH signal when touched and returns LOW when released, making it easy to interface with Arduino, ESP32, ESP8266, Raspberry Pi, STM32, and other microcontroller platforms. Its low power consumption and compact size make it suitable for battery-powered devices, smart home systems, automation projects, and embedded applications.
