TTP223B Capacitive Touch Sensor Single Channel Digital Sensor Module

The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module output is low, with low power consumption; When a finger touches the corresponding position, the module output is high, if not touched for 12 seconds, switches to low-power mode. The module can be installed in such surface plastic, glass, or non-metallic materials. 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 it hidden in the walls, desktops, and other parts of buttons.
