VCC pin is connected to the 5V power supply, GND pin is connected to the GND, and the OUT pin is connected to the digital I/O pin. The reasons for this development are durability, robustness, attractive product design and cost.Touch sensors, unlike mechanical devices, do not contain moving parts. Each key has its own output which by default goes high when you touch it. The module has 4 built-in LEDs, they light up whenever the respective button is touched, and you … Note that the total loading of touch pad size and capacitance of connecting line on circuit board can affect the sensitivity. Type: inching (Touchless: high level/Touch: low level; ) Working Voltage: DC2.2-5V； Working Current: 0.002mA(Standby); 0.025mA(Touch) Working Temperature: -40~85℃； Size: 15.4x11mm/0.60x0.43 inch In addition to the thin paper ( non-metallic ) covering the surface of the module , as long as the correct location of the touch , you can make hidden in the walls, desktops and other parts of buttons. In the normal state, the module output low, low power consumption. Capacitive touch is used in many electronic devices including smartphones and switches in modern homes and apartments. This capacitive touch sensor is an ideal alternative for the old-fashioned keypads and buttons. Upload by pressing the arrow in the circle to the upper left. Module use only 16 key mode. You can select fast mode or low power mode, direct mode or toggle mode, CMOS output or open drain output. The board can handle 4 touch pads independently and has 4 direct output pins. In some modules, a 1K resistor is inserted between the touch pad and pin 3 of TTP223, but the same is not tested at this time. An on-board LED will give a visual indication of when the sensor is triggered. Set the baud rate to 9600 on the lower right. When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode.
