Web-Based Access Control System using Wi-Fi Technology

Abstract

The Web-Based Access Control System utilizing Wi-Fi Technology aims to streamline the management of door access in spaces such as labs, lecture halls, and meeting rooms. This system enables the designated administrator to remotely lock or unlock doors via Wi-Fi, provided they are connected to the same network. Additionally, the administrator can track door usage by reviewing a log stored in a server database, which records who locked or unlocked each door. The project consists of two primary components: hardware and software. The hardware features a NodeMCU ESP8266 microcontroller with Wi-Fi capability, paired with a TowerPro SG90 servo motor that operates the door locks. The software is developed using the Arduino IDE for microcontroller programming and PHP for creating the web interface, where the administrator logs in using a username and password to monitor the system. The primary goal of this system is to enhance security and efficiency by automating door control and enabling real-time monitoring of room access. Only users with authorized credentials can interact with the system, ensuring its security. Ultimately, the project provides a reliable and convenient solution for managing access to rooms, improving both control and accountability.
