This project is a Smart Door Access Control and People Counting System designed using the ESP32 microcontroller. It allows users to unlock a door via a web interface after entering a password. Once the correct password is provided, the door opens for a limited time (10 seconds), then automatically closes. Meanwhile, the system uses two infrared (IR) sensors to detect the direction of movement—identifying whether a person is entering or exiting—and updates a real-time counter displayed on a web interface along with a live graph.

The aim is to provide a low-cost, responsive, and real-time system suitable for securing rooms, monitoring occupancy, and enhancing access control in small-scale environments such as labs, classrooms, or offices.

In today's world, real-time monitoring and automation are becoming essential in both residential and commercial environments. Manual tracking of occupancy or relying solely on physical access cards or keys has limitations in terms of scalability, logging, and remote monitoring.

This project addresses several modern needs:

* Remote access control using Wi-Fi and a web browser.

* Automated door management with time-based locking.

* Accurate real-time people counting using IR sensors and directional logic.

* Visual feedback using dynamic graphs and status messages on a web interface.

By combining IoT (Internet of Things) principles with basic access control and data visualization, this system serves as a foundation for smarter building management solutions.
