About this item

Digital Sensor TTP223B Capacitive Touch Switch Module:

The TTP223B Capacitive Touch Sensor Switch Module utilizes the TTP223B IC to provide an innovative touch-sensitive alternative to traditional push-button switches. This module is designed for ease of integration and offers reliable performance across various applications.

Product Overview:

• The module outputs a low signal in a low-power state. Upon detecting a touch on the designated area, it transitions to a high output and enters quick-response mode.
• After 12 seconds of inactivity, it reverts to low-power mode to conserve energy.
• The sensor can be concealed behind non-metallic materials like glass, acrylic, or paper, enabling seamless integration into projects while maintaining functionality.

Key Features:

• Low Power Consumption: Ideal for battery-powered devices and energy-efficient applications.
• Wide Operating Voltage: Supports 2V to 5.5V DC power supply.
• Compact Design: Includes four M2 screw holes (2.2mm diameter) for secure installation and modular assembly.
• Replace Push Buttons: Offers a sleek, touch-sensitive alternative to mechanical switches.
• Indicator LED: A green LED lights up to indicate power status.
• Robust Output:
  • Sink Current: 8mA @ 3V, VOL = 0.6V.
  • Pull-Up Current: 4mA @ 3V, VOH = 2.4V.

Interface and Usage:

• Control Pins:
  • GND: Connect to ground.
  • VCC: Power supply input (2-5.5V DC).
  • SIG: Digital signal output pin.
• Touch Area: The module features a touch-sensitive area resembling a fingerprint, optimized for finger activation.
• Installation: Mount the module using the provided screw holes for easy positioning and secure integration.

Applications:

• Home Automation: Replace traditional switches for a modern touch interface.
• Embedded Projects: Integrate into microcontroller-based systems for interactive control.
• Furniture and Appliances: Create concealed touch controls on non-metallic surfaces.

The TTP223B Capacitive Touch Sensor Module delivers simplicity and efficiency, making it an excellent choice for projects that demand touch-sensitive control solutions.
