Precision People Counting: Utilizing Dual IR Sensors for Accurate Entry and Exit Monitoring

In the original system for counting the number of people passing through a doorway, a single IR sensor was used. However, this setup faced challenges when people entered and exited simultaneously. The system could not accurately distinguish between entry and exit movements, resulting in counting errors. This research aims to improve the accuracy of people counting by employing two IR sensors instead of one. With this dual-sensor setup, the system can accurately detect the direction of movement, whether a person enters through the exit or exits through the entry. This allows for 100% accurate people counting, regardless of the direction individuals are moving, thereby solving the limitations of the previous single-sensor approach. The proposed solution ensures reliable performance in various scenarios where foot traffic flows in opposing directions.
