TTP224 - 4 channel Digital capacitive touch sensor module
4 Channel Digital Capacitive Touch Sensor Module uses the touch-sensing IC TTP224 to sense the touch input. Making it easy to add capacitive touch input to your project. The touching detection IC is designed for replacing traditional direct button keys with diverse pad sizes. The module has 4 touchpads. Power the module with a 2.4V to 5.5V DC current. And the touchpad is all active to sense the input. Digital Capacitive touch sensor has a good advantage. It allows electronic equipment to sense when your finger is within a few millimeters of the surface. It simulates a button “press” just like the push on a button.
