IOT PROJECT: PEOPLE COUNTER USING IR SENSORS

Abstract: A people counting system was designed and implemented using infrared (IR) sensors to accurately track the number of individuals entering and exiting an enclosed space in real time. The system was simulated and tested using Cisco Packet Tracer version 8.0.0 alongside embedded hardware prototyping tools. Two IR sensors are placed at the entry and exit points of a room; when a person passes through, the sensors detect interruptions in the infrared beam and increment or decrement a counter accordingly. The count data is processed by a microcontroller and transmitted over the local network to a centralized server for monitoring. The server is accessible only through a secured HTTPS connection on port 443. Internally, department routers are interconnected for seamless access to the monitoring application. Network Address Translation (NAT) is configured on the company router to map public IP addresses to private device addresses. Switches are used to optimize device connectivity across both the campus network and the broadband connection. Connectivity was verified using ping tests from all segments of the network to confirm full reachability of the people counter server and monitoring dashboard
