Description:

The TTP223B Capacitive Touch Sensor Module provides a touch-sensitive input, enabling you to create touch-based controls for various electronic projects without conventional physical push-buttons. Utilizing the TTP223B IC, this module detects changes in capacitance when a finger touches the designated area, switching between low-power mode and fast mode based on touch input.

Key Features:

  1. Capacitive Touch Sensing: Detects when a finger touches the module's surface, outputting a high signal.
  2. Low Power Mode: Outputs a low signal when not touched, conserving power.
  3. Fast Mode: Switches to fast mode upon touch, providing a quick response with a high signal output.
  4. Auto Power-Down: Automatically reverts to low-power mode after 12 seconds of no touch input, further saving energy.
  5. Easy Installation: Can be installed on non-metallic surfaces such as plastic, glass, wood, or even behind thin non-metallic materials like paper, allowing for concealed touch-sensitive buttons on walls, tabletops, and other surfaces.

Applications:

This capacitive touch switch module is ideal for various electronic projects requiring touch-based controls, including:

  1. Touch-sensitive lamp switches
  2. Touch-based control panels for home automation
  3. Touch-sensitive interactive displays and interfaces
  4. Hidden touch buttons in furniture or walls
  5. Touch-sensitive input for DIY electronic gadgets and toys

Specifications:

Item Min Typical Max Unit
