TTP223B 1-Way Capacitive Touch Switch module
TTP223B 1-way capacitive touch switch module with digital output—perfect for touch-activated switches, home automation, and DIY electronics projects.
Description
The TTP223B 1-Way Capacitive Touch Switch Module is a compact and reliable sensor designed to replace traditional mechanical switches with a touch-sensitive interface. It features a single-touch input that provides a digital output, allowing it to easily interface with microcontrollers such as Arduino, ESP32, ESP8266, and Raspberry Pi.
Operating at a wide voltage range (2V–5.5V), the module is highly responsive and requires only a light touch to trigger. Its small form factor makes it ideal for touch-activated lights, home automation, DIY electronics, and interactive projects. The TTP223B module offers low power consumption, stable performance, and easy integration, making it suitable for both beginners and advanced electronics projects.
