An Integrated Low Cost IoT Node based on Discrete Components for Customized Smart Applications; Use case on Precision Agriculture

This work depicts the concept and methodology as well as the architecture and physical implementation of a low-cost Internet of Things (IoT) node for customized smart-applications. The presented node efficiently integrates state-of-the-art discrete electronic components able to support a variety of smart applications. The node comprises an ARM CortexM based microcontroller designed for low power wireless applications, a power management unit and several sensors for which special adapters have been implemented. The proposed IoT node is being validated in vineyard fields, in the framework of precision agriculture practice, with the aim of collecting critical environmental parameters, to be used as input to algorithmic models for the detection and subsequently prevention of related agricultural diseases.
