Raspberry Pi based Smart Classroom Architecture with Local Network

Abstract

Classrooms are important building blocks of a school campus. Therefore, a feasible architecture for building and running smart classrooms is essential. Today all online education system is based on the browser/server structure or client/server structure and for this system required the computer to every student. As the number of student increases cost of education also increases. In small schools and institutes could not able to afford a computer to every student. Instead, we aim to design an embedded device with only one master computer and number of slave units. Raspberry Pi has the capability of being configured as an access point and as a web server, so it can be used for creating applications reachable from mobile devices without needing an Internet connection. The proposal is based on the possibility for students to Answer questionnaires from their mobile devices. The teacher can observe answers in real time. This solution adds dynamism integrating the existing mobile devices in the classroom. It eliminates the use of computers or laptops to each student which reduces size and cost of the project. Programming language used in this project would be HTML alongwith Python, Operating System will be Raspbian and Questionnaire Software will be Node-Red. This paper explains the proposal features in terms of used hardware and software, as well as the functional tests performed and their implementation allowing replication.
