TTP224 4-Channel Capacitive Touch Switch is a 4 switch digital touch sensor with capacitive sense technology, the TTP 224 IC offers capacitive sense input feed designed for touch pad control, followed by 4- finger sized touch pad. The board has jumper's arrangement to change the key press output mode in Timed or Toggle, Active High or Active Low. A separate jumpers adjustments are provided for changing the response time of the press key: 60mS fast mode or 160mS in Low power. The output side of the board has 6 pin headers, with 4 pins to be connected with the digital I/O of any microcontroller board (Arduino, ARM STM32). 4 status LED SMD type are provided for check the status of the each pressed key.

Features:

• 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 traditional direct button key with diverse pad size. The module has 4 touch pads. Power the module with 2.4 ~ 5.5V DC and the touch pad is all active to sense the input.
• Four 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.
• Thus, the 4 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 4 pads are available on this module. The sense-pads can also be extended with a wire or almost any conductive material.
