Paper presented at the international scientific conference WFIoT 2022 in Japan

At the international scientific conference WFIoT 2022, held from October 31 to November 4, 2022 in Yokohama, Japan, a paper entitled "IoT Based Network Model And Sensor Node Prototype For Precision Agriculture Application" authored by Josip Spišić, Josip Balen, Dear Žagar and Vlatko Galić. The work was accepted after an international review process. This paper presents an IoT network model and a sensor node prototype for use in precision agriculture, which consists of an infrared sensor and a general-purpose microcontroller for collecting data from agricultural fields. The architecture of our model is extremely flexible and provides a machine learning data analysis solution that enables the processing of small-sized data at the edge of the network (sensor nodes) and the processing of large volumes of data in real-time from numerous nodes in the cloud. We use LoRaWAN™, a broadband network protocol as the transmission protocol in our solution, which has low power consumption, long range capability, is affordable and low maintenance, making it perfect for large fields and variable number of sensor nodes. According to the first device testing results presented in this paper, our device could provide an affordable means of spatio-temporal reading in the fields.
