The IoT Signage Display is an Internet of Things (IoT) project that combines Alert system and Public display, built with MQTT. The project follows a clean, modular pipeline where sensor data acquisition, connectivity, and presentation stay separated, making it easy to test, extend, and present. It showcases practical IoT techniques while producing a working, demo-ready system.
Manual monitoring and control for this task is slow, inconvenient, and cannot be done from anywhere. Without an IoT approach built on Public display and MQTT, users cannot connect real-world devices to the internet and manage them efficiently in real time.
This project applies IoT techniques through Alert system, orchestrated with MQTT and Public display. The system is designed for connectivity and reliability, with sensing, networking, and clear evaluation. It produces consistent, reusable results and can be adapted to related connected applications with minimal changes.

Remote access and control
The project is layered: the sensing layer acquires data through Alert system; the connectivity layer publishes and processes it with MQTT and Public display; and the output layer monitors and controls via Data gateway. Shared connectivity, alerting, and dashboard modules support all layers, keeping the system robust and easy to extend.
