TTP223 Mini 1-Way Touch Key Red capacitive touch sensor module
TTP223 mini 1-way red capacitive touch key module with digital output—ideal for touch-activated switches and DIY electronics projects.
Description
The TTP223 Mini 1-Way Touch Key Module is a compact and reliable capacitive touch sensor designed to replace mechanical buttons with a simple touch interface. Featuring a red LED indicator, this module provides single-touch detection with digital output, making it easy to interface with microcontrollers such as Arduino, ESP32, ESP8266, and Raspberry Pi.
It operates at a wide voltage range (2V–5.5V) and is highly responsive, requiring only a light touch to trigger the output. Its mini size allows it to be integrated into DIY electronics, touch-activated lights, home automation systems, and interactive projects.
The TTP223 module provides stable performance, low power consumption, and easy wiring, making it ideal for both beginners and advanced electronics enthusiasts.
