The Smart Siren System is an Internet of Things (IoT) project that combines Camera capture and Auto response, built with Gas sensor. 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 Auto response and Gas sensor, users cannot connect real-world devices to the internet and manage them efficiently in real time.
This project applies IoT techniques through Camera capture, orchestrated with Gas sensor and Auto response. 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.
