Description of TTP224 4 Way Capacitive Touch Sensor Module
Quick Overview
The TTP224 4-Way Capacitive Touch Sensor Module offers a simple and responsive touch interface for your projects. Using capacitive sensing technology, it provides four touch-sensitive pads that can replace traditional buttons. It is ideal for a wide range of applications, from consumer electronics to industrial control systems.
How It Works
The module employs capacitive sensing technology to detect touch. It comprises four touch-sensitive pads and an onboard TTP224 IC that processes the touch signals. When a finger comes into contact with a pad, it changes the capacitance, which is detected by the IC. The IC then outputs a corresponding signal through its pins, which can be read by a microcontroller.
