Product Introduction:

The module is a capacitive jog touch switch module based on a touch detection IC (TTP223B).

Under normal conditions, the output of the module is low, and the mode is low-power mode; When touching the corresponding position with your finger,

The module will output a high level, and the mode will be switched to fast mode; When there is no touch for 12 seconds, the mode switches to low-power mode again.

You can install the module on the surface of non-metallic materials such as plastic and glass, and cover the surface of the module with a thin piece of paper (non-metal), as long as the touch position is correct, you can make a hidden button on the wall, desktop, etc.

This module can help you solve the problem of regular push-type buttons.
