The 4 Channel Capacitive Touch Sensor Module uses the touch-sensing IC TTP224 to sense the touch input thus making it easy to add capacitive touch input to your project. The touching detection IC is designed for replacing the traditional direct button key with a diverse pad size. The module has 4 touchpads. Four-Channel Capacitive Touch Sensor Module is easy to interface.
When a capacitive load (such as a human hand) is in close proximity to the sense-pad, the sensor detects the change in capacitance and activates the switch. Custom sense-pads can be made from nearly any conductive material and these sensors can detect touch through thin layers of non-conductive materials such as glass, plastic, fabric, or even wood. The sense-pads can also be extended with a wire or almost any conductive material.
It can be used along with a microcontroller or an Arduino or even without one.
