Development of Web-Based Smart Security Door Using QR Code System

Providing a security system for any electrical equipment has become a vital interest in which the latest technologies are being adopted to serve this purpose. University classrooms usually implement automatic door lock attached with a sensor to enable access into the classroom. The access door needs a more autonomous, integrated, and intelligent functionality to improve smart classroom’s usability. This work presents the development of a secure door lock system by utilizing Quick Response (QR) technology and Raspberry Pi processor for accessing the university laboratory or classroom where the authorized person will also be able to monitor who have accessed to the classroom or laboratory. The data logging system is developed to track the ingoing and outgoing activities when accessing the security door from the web-based website server. In this vein, the authorized individuals are only the ones who will get the permission to access the doors. This is a preliminary work to test the system’s functionality to be used for different properties and facilities such as office, classroom and laboratory. Based on the result and data collection, the testbed development has worked properly as an initial study to provide a smart security door using QR code system.
