TTP223 Capacitive Touch Sensor Module

TTP223 Capacitive Touch Sensor Module – Touch Switch Button IC Module for Arduino
The TTP223 Capacitive Touch Sensor Module is a smart touch-based input switch that replaces traditional mechanical buttons. It detects human touch by sensing changes in capacitance and provides a clean digital output signal. This module is widely used in Arduino, ESP32, ESP8266, and other microcontroller projects for touch-controlled interfaces, smart switches, and DIY electronics.

Features:

• Capacitive Touch Sensing: Detects human touch without physical pressure
• Single Touch Input: One-channel touch detection for simple control
• Digital Output: Provides stable HIGH/LOW signal to microcontrollers
• Adjustable Modes: Supports toggle and momentary output options
• High Sensitivity: Works through plastic, glass, or non-metal surfaces
• Low Power Consumption: Ideal for battery-powered projects
