Product Description

The module is based on a touch-sensing IC TTP223B capacitive touch switch module. In the normal state, the module output low, low power consumption, but when a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode. Module can be installed in such as surface plastic, glass of non-metallic materials. You can put to a thin paper ( non-metallic ) cover the surface of the module, when touch the correct location of the module, that you can put it hidden in the walls, desktops and other buttons. Features:TTP223B Chip. Low power consumption, and power supply is DC 2-5. 5V. Green LED Indicator, and it is bright when power on right. Control port: GND, VCC, SIG. Both positive and negative can be used as a touch surface, and replace the traditional touch of a button. Specification:.
