TTP223B Capacitive Touch Sensor Module

TTP223B Capacitive Touch Sensor Module

The TTP223B Capacitive Touch Sensor Module is a compact and easy-to-use touch switch module designed for modern electronic and DIY projects. Based on the TTP223B touch sensing IC, this module can replace traditional mechanical push buttons with a simple touch interface, providing smooth and reliable touch control.

The module detects human touch on the marked sensing area and outputs a digital HIGH signal when activated. Its low power consumption and fast response make it ideal for battery-powered applications, smart control panels, home automation systems, and interactive electronics projects.

The touch sensor can even work through thin non-metallic surfaces such as paper, acrylic, plastic, or wood, allowing hidden touch button designs for sleek and modern projects.
