Скачать или смотреть Bidirectional Visitor Counter Academic Project | Entry–Exit Counting Using IR Sensors

This video presents an academic project demonstration of a Bidirectional Visitor Counter developed using two IR sensors and a 6-digit LCD display.

🔹 Project Objective

To design a simple system that can count people or objects entering and exiting a passage and display the count in real time.

🔹 Working Principle

Two IR sensors are placed on either side of the entry path

When an object moves in one direction, the count increments

When an object moves in the opposite direction, the count decrements

The system identifies direction based on the order of sensor activation

The current count is displayed on a 6-digit LCD

🔹 Key Learning Outcomes
