The aim of the project is to demonstrate the functionality of a monitoring system for olive trees based on IoT sensor networks. For this purpose, a reference sensor network will be established on a parcel of the Tunisian Olive Institute near Sfax. The Olive Institute will be involved in the project and will learn how to install and maintain the sensors in order to play a key role in the future maintenance of the sensor network. At the same time they act as users of the area-based indicators and shape the development of the system. At the end of the project, an operational system will be available as a potentially marketable product for scaling and application on a larger level.
