The integration of advanced technologies into agricultural practices, often referred to as precision agriculture, represents a scientific and engineering approach to optimizing farming operations, improving productivity, and promoting sustainability. This thesis is part of the IRIDE project, an interregional initiative primarily aimed at conserving water in irrigation systems and providing automated data-driven support to farmers. The core of the thesis work involves the hardware design of a device dedicated to collecting sensor data related to water content of the soil, environmental conditions and health status of the cultivated plants. The deployment of embedded electronic systems directly in agricultural fields and orchards enables the collection of accurate measurements and allows the implementation of sophisticated algorithms for the monitoring and prediction of plant health status.
