Control interface: a total of 3 pins (GND, VCC, SIG), GND is ground, VCC is power supply, SIG is digital signal output pin;
Power indicator: green LED, glow when powered on correctly;
Touch area: The inner area of the fingerprint-like icon, which can be triggered by a light touch of the finger.
Positioning holes: 4 M2 screw positioning holes, the hole diameter is 2.2mm, so that the module is easy to install and position, and the combination between modules is realized;
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.
