Touch Sensor

Touch Sensor Jog -Type Touch Module Capacitive Touch Buttons

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; 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
