TTP229 4x4 Keyboard 16-Channel Capacitive Touch PAD Switch Sensing Detector Module

TTP229 4x4 Keyboard is a sixteen 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.

Due to its touch functionality, the 16 Channel Capacitive Touch Sensor Module can be hidden in wall or other places, a perfect alternative to get rid of the conventional push-button troubles. A total of 16 pads are available on this module. The sense-pads can also be extended with a wire or almost any conductive material.
