Description
Product Overview
The WWZMDiB TTP223B digital capacitive touch sensor switch module is engineered for precision touch detection across a wide range of non‑metallic surfaces. Built with a compact footprint of 3.94 × 2.56 × 0.59 inches, the module houses a high‑sensitivity TTP223B IC that reacts instantly when a finger or conductive object makes contact. It operates from a flexible supply voltage of 2 to 5 V DC, making it compatible with both 3.3 V and 5 V logic levels commonly found in Arduino, Raspberry Pi, and other microcontroller platforms.
Designed for low power consumption, the module stays in a low‑energy state when idle and only switches to a high output when touched. After 12 seconds of inactivity the device automatically returns to its low‑power mode, extending battery life for portable or remote installations. The module’s robust plastic housing protects the internal circuitry while allowing easy mounting on surfaces such as acrylic, glass, or standard plastic panels, enabling hidden or flush‑mount designs that blend seamlessly into consumer products, prototypes, and hobbyist projects.

Usage
Because the sensor can be attached to any non‑metallic material, it is ideal for a variety of applications ranging from smart home control panels to interactive museum exhibits. Hobbyists can replace traditional mechanical push‑buttons with this touch sensor to create sleek, button‑less interfaces for lighting control, motor activation, or audio playback. In educational settings, the module serves as a hands‑on tool for teaching capacitive sensing principles, allowing students to experiment with touch‑triggered events without the need for complex wiring.
For industrial prototypes, the sensor’s ability to operate at low voltages and its fast response time make it suitable for safety‑critical systems where rapid detection is essential. Its compatibility with both Arduino and Raspberry Pi platforms means developers can quickly integrate the sensor into existing codebases, using simple digital I/O pins to read touch events and drive actuators, LEDs, or communication modules.

FAQ
What voltage range does the sensor support?
The module is designed to operate safely between 2 V and 5 V DC, allowing it to be used with both 3.3 V and 5 V microcontroller boards.
Can the sensor be mounted on metal surfaces?
For optimal performance the sensor should be mounted on non‑metallic materials such as plastic, glass, or acrylic. Metal surfaces can interfere with the capacitive field and reduce sensitivity.
How does the low‑power mode work?
When the sensor detects no touch for 12 seconds, it automatically switches to a low‑power state, reducing current draw to a few microamps. Touching the sensor again wakes it instantly.
Is the module compatible with Raspberry Pi?
Yes. The sensor’s digital output can be connected directly to any GPIO pin on a Raspberry Pi. Simple Python scripts can read the high/low state to trigger actions.
What is the typical response time?
The TTP223B IC provides a response time of less than 10 milliseconds, delivering near‑instantaneous detection for responsive user interfaces.
