TTP223B Digital Touch Sensor Capacitive Touch Switch Module
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
Features
Low power consumption
Power supply for 2 ~ 5.5V DC
Can replace the traditional touch of a button
Four M2 screws positioning holes for easy installation
