Description:
The TTP223 is a single-channel capacitive touch sensor module that provides a simple digital switch output. It serves as a modern replacement for traditional push-buttons, activating when a finger is brought near its sensing pad. Operating on a low voltage, it outputs a high signal upon touch. The module is incredibly small and energy-efficient, making it ideal for battery-powered projects, interactive displays, and custom human-interface devices where a sleek, non-mechanical button is desired.
