Capacitive Touch Switch Sensor Module (TTP223B)

Use this capacitive sensor instead of a traditional switches for your Arduino projects and other electronic.  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; When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode.    Jog type : the initial state is low , high touch , do not touch is low ( similar touch of a button feature )    Module can be installed in such as surface plastic, glass of 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 hidden in the walls, desktops and other parts of buttons
