In stock
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:
- Capacitive Touch Sensing: Detects when a finger touches the module's surface, outputting a high signal.
- Low Power Mode: Outputs a low signal when not touched, conserving power.
- Fast Mode: Switches to fast mode upon touch, providing a quick response with a high signal output.
- Auto Power-Down: Automatically reverts to low-power mode after 12 seconds of no touch input, further saving energy.
- 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:
- Touch-sensitive lamp switches
- Touch-based control panels for home automation
- Touch-sensitive interactive displays and interfaces
- Hidden touch buttons in furniture or walls
- Touch-sensitive input for DIY electronic gadgets and toys
