The Interactive Digital Nameplate with Visitor Sensing

The traditional concept of nameplates has evolved from simple identification to a symbol of pride and welcome for homes and offices. With advancements in technology, the digital nameplate brings a revolutionary way to greet and inform visitors, combining elegance with functionality.

The New Age of Nameplates:

Digital nameplates are an innovative leap forward, offering dynamic content display and interactive features. Unlike static conventional nameplates, digital versions can display a variety of messages, from family names to welcoming greetings, all in a sleek, modern design.

Key Features of Digital Nameplate:

  • Dynamic Family or Office Name Display: The nameplate can scroll through different names or display the office name along with a company tagline, offering a customizable and comprehensive identification system.
  • Personalized Welcome Messages: Integrated with an ultrasonic sensor, the nameplate detects when a visitor is near and displays a friendly greeting or any other pre-set message.
  • Away Messages: For times when you’re not at home or the office is closed, set messages to inform visitors of your absence and expected return.
  • Scrolling Display: The LED display provides a bright and moving text feature, making the information more noticeable and attractive.

How It Works:

The heart of the digital nameplate is the Atmega 328 Microcontroller, which controls the LED display and interacts with the ultrasonic sensor. Here’s a brief overview of its operation:

  • Message Control: The microcontroller stores and scrolls messages on the LED display, which can be customized and updated as needed.
  • Visitor Detection: The ultrasonic sensor detects the presence of a visitor within a certain range and triggers the welcome message.
  • Customizability: Users can set and change the displayed names, welcome messages, and away messages through a connected keypad or other input devices.

Components of Digital Nameplate:

  • Atmega 328 Controller: Manages the functionalities and interactions of the nameplate.
  • Ultrasonic Sensor: Detects the presence of visitors and activates the display messages.
  • LED Display: Visually represents the name and messages in a bright and clear manner.
  • Input Keypad: Allows for customization and input of names and messages.
  • Supporting Electronics: Includes buzzer for audible alerts, transformers, regulator circuitry, switches, LEDs, PCB Board, resistors, capacitors, transistors, cables, and connectors.


The digital nameplate represents a blend of tradition and technology, providing a smart, welcoming touch to any home or office. As technology continues to integrate into everyday life, digital nameplates offer a customizable, interactive, and stylish way to greet visitors and identify your space.
