TTP223 Capacitive Digital Touch Sensor IC Module For uno Voltage 2.0V-5.5V

Description

• This module is a capacitive jog type touch switch module based on the touch detection IC (TTP223B).
• Normally, the module outputs a low level, and the mode is low power; When the corresponding position is touched with a finger, the module outputs a high level, And the mode changes to a fast mode
• When there is no contact for 12 seconds, the mode changes to a low mode power mode.
• The module can be mounted on the surface of non-metallic materials such as plastic and glass, and a thin piece of paper (non-metallic) can be placed on the surface of the module.
• As long as the touch is correct, it can be hidden in the wall button, desk, etc.
• This module allows you to eliminate the hassle of conventional buttons.

Module Features:

• Jog type: The initial state is low level, the jog is high level, and the jog is low level (similar to the touch button function)
• Low energy consumption
• Power supply can be 2~5.5V DC
• Both the front and the back can be used as touch surfaces, which can replace traditional touch buttons
• 2 Ø 2mm screw positioning holes for easy installation
• Control interface: a total of 3 pins (GND, VCC, OUT), GND is ground, VCC is the power supply, OUT is the digital signal output pin;
• Touch indicator: Red LED, the touch will light up;
• Touch Area: An empty blue area that can be activated with a finger touch.
• Positioning hole: 2 M2 screw positioning holes, 2mm aperture, easy to install and position the module
