The Visitor Counter Cum Energy Saver using Seven Segment Display with Arduino is an innovative project that combines a visitor counter and an energy saver into a single device.
The project counts how many people enter and leave a room using an Arduino Uno microcontroller board and four seven-segment displays. The count can be increased and decreased using two push buttons.
The room's electrical appliances are managed by an AC relay module to save electricity. While there are no visitors present, the appliances will be turned off, and when there are, they will be switched on.This feature helps to save energy, reduce costs, and promote sustainability.
The project is helpful in a variety of public environments, especially schools, hospitals, and offices, where it is important to keep track of the number of people in a space while simultaneously reducing energy use.The project is relatively simple to build and can be customized to suit specific requirements. The project is a practical demonstration of how technology can be used to solve real-world problems and make our lives easier while promoting sustainable development.
