G. Tejaswi, Mopuru Rajesh, Veeramreddy Pratap Reddy, Balli Sarath Chandra, Nanda Bhaskar Rao 03 04 Traditional information dissemination in educational institutions relies heavily on manual paperbased notice boards which are prone to delays high maintenance costs and physical constraints This paper proposes a centralized realtime IoTbased Campus Display Board ICDB system powered by the highperformance Raspberry Pi 5 The proposed architecture integrates a webbased administrative server with distributed edge nodes via a secure IoT communication layer Utilizing a Flaskdriven backend and a dynamic HTML5CSS3 frontend authorized administrators can remotely broadcast multimedia contentincluding highdefinition video static images and emergency alertsfrom any location The Raspberry Pi 5 serves as the core processing unit leveraging its quadcore capabilities and improved networking stack to ensure lagfree rendering and continuous synchronization with the server via a pollingbased manifest protocol Experimental results indicate that the system significantly reduces the latency between announcement creation and public display compared to conventional methods Furthermore the modular design promotes sustainability by eliminating paper waste and offers a scalable infrastructure for future smartcampus integrations such as AIdriven content scheduling and automated cloud synchronization This research demonstrates a costeffective energyefficient and userfriendly solution for modernizing institutional communication and enhancing administrative transparency in a digitally driven academic environment Copyright (c) Journal of Science Engineering Technology and Management Science.
