Modeling of a Pandemic Compliant Smart Classroom Door for Nigerian Education System

This article looked at the concept of a pandemic as witnessed in 2020 and developed a system (smart classroom door) that can come in handy in the event of a similar situation, particularly in a school environment. Sensors and microcontrollers were integrated into the classroom door to observe, implement and help enforce the guidelines marshaled out as criteria for lifting the Covid-19 pandemic lockdown in 2020. A high-performance computer board was used to integrate hardware devices that provided web interfaces for applications. Python programming language was used in the implementation because it is supported by commercial and open-source operating systems used in the work. Firebase database is used for cloud recording and synchronization in real time with every connected client. The system recognized the profiled students and also identified when a recognized face eventually puts on a face mask before granting such student access to enter the classroom. Any face that was recognized but failed to put on a face mask when prompted to do so was not granted access. Whenever access is granted to a student, the system smoothly updates the Firebase in real time. The system was also able to mark an offline attendance whenever there was no Internet connection.
