IoT based Smart Wi-Fi Announcement System

This research presents the development of an IoT-based digital notice board system that aims to improve the efficiency and sustain ability of information dissemination in public spaces. The system replaces traditional physical notice boards with an LCD display connected to the internet, enabling remote content updates through a web-based interface. By eliminating the need for manual updates, the system reduces labor costs, saves time, and ensures timely dissemination of information. The system integrates user authentication for secure access and utilizes Wi-Fi for reliable and efficient communication, overcoming the limitations of traditional communication methods. This research aligns with Sustainable Development Goal 9 by promoting innovation and sustainable infrastructure through the efficient utilization of technology for public information dissemination. The system offers a user-friendly and sustainable alternative to traditional notice boards, enhancing communication and accessibility for all.
