TTP223 Capacitive Touch Sensor Module – The Modern Switch
Upgrade your project with a touch of elegance. No moving parts, no mechanical wear—just smooth, reliable switching.
The TTP223 module is a single-channel touch sensor that acts just like a momentary push-button. It is incredibly small, low-power, and easy to integrate into any 2V to 5.5V system. Whether you are building a smart lamp, a hidden cabinet switch, or a custom control panel, this sensor provides a clean, professional feel to your user interface.
