TTP223 Touch sensor switch module

The touch sensor is an electronic sensing module designed to detect a finger touch and provide an electronic input. It is suitable for Arduino, ESP32, robotics, automation, IoT, and STEM learning projects where a controller needs information about its surroundings or user interaction.

The module can typically be connected to a microcontroller using simple power and signal connections. Its output can be used to trigger LEDs, buzzers, relays, motors, displays, alarms, or software actions depending on the project. It is useful for both beginner experiments and practical prototypes.

This sensor provides a convenient way to add responsive, real-world input to electronic systems without building the sensing circuit completely from individual components.

Features:
• Touch-activated input
• Digital output for microcontrollers
• No mechanical button required
• Useful for interactive control projects
