Description
Capacitive Touch Sensor Module uses the touch-sensing IC TTP223 to sense the touch input. The touching detection IC is designed for replacing the traditional direct button key with a diverse pad size. The module has a single touchpad, power the module with 2 ~ 5.5V DC and the touchpad is all active to sense the input.
Single Channel Capacitive Touch Sensor Module is easy to interface. It can be used along with a microcontroller or an Arduino or even without one. 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.
