The TTP223B Capacitive Touch Sensor Module is a compact, efficient digital touch switch ideal for replacing traditional mechanical buttons in DIY electronics projects. Based on the TTP223B IC, this module senses human touch and outputs a digital signal. It operates in momentary mode—touch to turn ON and release to turn OFF—providing intuitive interaction for your devices.Thanks to its capacitive sensing, the module can detect touches through non-metallic materials like plastic, glass, or paper, allowing you to build hidden or embedded touch switches in walls, desks, or control panels. With built-in low-power functionality, it conserves energy by entering sleep mode after 12 seconds of inactivity.Perfect for Arduino enthusiasts, hobbyists, and product developers, this module comes in a pack of 2 and is easy to integrate with a wide range of microcontroller projects.
