- Development of server side application for smart waste systemsPublication . Merah, Soheyb; Lopes, Rui PedroThis thesis presents the design and implementation of a scalable backend server for real-time monitoring and analytics of smart waste management systems. The server collects data from decentralized sensors installed in urban dumpsters for detection and classification of volatile organic compounds through an electronic nose sensor. Upon detecting hazardous gas thresholds, the system generates automated alerts to waste-collection teams, thereby improving worker safety and reducing environmental risks. Additionally, the backend provides a web-based dashboard for visualizing historical and live analytics, enabling municipal authorities to optimize collection routes, predict fill-level trends, and reduce operational costs. The architecture leverages a microservices approach with RESTful APIs, a time-series database for sensor data storage, and message-queueing for event-driven notifications. The proposed solution contributes to the fields of Internet of Things (IoT) in smart cities, environmental monitoring, and backend systems engineering.
