TTP229 4×4 Capacitive Touch Keypad Module 16 Channel

TTP229 4×4 Capacitive Touch Keypad Module 16 Channel is a sixteen Channel Capacitive Touch Sensor Module is easy to interface. This TTP229 touch keypad module 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 4×4 touch keypad Arduino. The sense-pads can also be extended with a wire or almost any conductive material.
