Real-Time Bidirectional Visitor Counter with Wireless Smart Power System

Today's electronic devices are getting better at making our lives easier. Many people face problems keeping track of what happens around them. Our work helps visitors have a better experience by controlling lights automatically. This new system counts how many people enter a room and turns lights on or off based on that number. When someone walks into a room, the counter goes up by one and shows this on a seven-segment display. The lights turn on at the same time. When someone leaves, the counter goes down by one. If everyone leaves the room, the lights turn off completely. Our system shows the total number of people on both a display screen and Google Firebase so anyone can check it easily. We tested our work and found it works correctly 96 % of the time. This is 6 % better than older systems. Our method is a big step forward for counting people automatically and saving energy in buildings.
