The aim of the Dragonfly project is to implement enabling technologies for the deployment, and management of a cost-effective mobile remote sensing framework (or cyber physical system) for monitoring freshwater quality towards water reservoirs protection against pollution. The module is composed of several sub-systems optimized for the collection of relevant water quality data and its transmission in real time to a central monitoring and control unit. The data will make it possible to identify sources of contamination and its evolution, being, therefore, a decision-making tool to trigger environmental protection mechanisms and lead to the rapid identification of the origins of the problem(s) and their respective resolution.
