Touch Button module TTP223B

This module can be used to turn something on or off by touching the touch area on the module.

Power: 2.5-5.5V
 

• The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module outputs low, with low power consumption; when a finger touches the corresponding position, the module outputs high. If not touched for 12 seconds, it switches to low-power mode.
• Jog type: the initial state is low, high on touch, and low when not touched (similar to a button).
• The module can be installed on surfaces such as plastic and glass, or other non-metallic materials.
• In addition to a thin paper (non-metallic) covering the module surface, as long as the touch location is correct, you can hide it in walls, desktops, and other areas for buttons.
  
  Features:
