DESIGN AND IMPLEMENTATION OF SMART CONTROL ACCESS SYSTEM IN INSTITUTIONS: CASE OF EXAM ROOMS AT ULK

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.
