Abstract:
This project presents the design and implementation of a smart access control system for exam
rooms using NodeMCU, RFID technology, LCD display, and Wi-Fi connectivity integrated
with a Django-based backend. The primary objective is to enhance security, rapidity and
streamline the management of student access during examination periods.
The system utilizes RFID cards for student identification, where each card is registered in a
database hosted on a Django server. When a student scans their RFID card at the entrance,
the NodeMCU retrieves the card data and sends a request to the Django server to verify the
student's identity and access permissions. Based on the response, the system displays an
appropriate message on the LCD screen, indicating whether access is granted or denied.
Additionally, visual indicators such as green and red lamps provide immediate feedback on the
access status.
A website with “ulkcontrolservice.onrender.com” as domain name is deployed to ensure every
student can see his/her personal details and a messaging system where he/she can claim or
request access to administrators of school who manage access and individual details on their
interface of the same website. This project addresses the need for a secure, fast, reliable, and
user-friendly access control solution in educational institutions, aiming to prevent
unauthorized entry and enhance the rapidity in accessing examination rooms.
The implementation details, system architecture, and potential applications of the proposed
solution are discussed, highlighting its effectiveness and scalability for broader use in similar
scenarios.
