TTP223 1 Channel Digital Capacitive Touch Sensor Module (Single Touch Switch Module)

The TTP223 1 Channel Digital Capacitive Touch Sensor Module is a compact touch detection module designed to replace conventional mechanical push buttons with reliable capacitive touch sensing. Based on the TTP223 capacitive touch sensor IC, the module detects the touch of a finger and provides a digital HIGH or LOW output signal for easy interfacing with microcontrollers. Operating from 2.0V to 5.5V, it is compatible with Arduino, ESP32, ESP8266, STM32, Raspberry Pi, and other embedded platforms. The module is ideal for touch switches, home automation, consumer electronics, interactive devices, and embedded control systems.
