A focus on communication solution in agricultural telemetry systems

Abstract

Digital agriculture emphasizes the need for the development of telemetry systems that enabling the monitoring of the crops and the agricultural machinery. The key of digital agriculture is connectivity. Unfortunately, long-range connectivity is a limited resource in rural areas. To fill this gap, in this work, a communication solution based on LoRaWAN for telemetry systems is proposed. As proof of concept, an end-to-end telemetry system is implemented. The telemetry system collects data of seeding from ISOBUS agricultural machinery and sends them to a cloud-based service through a LoRaWAN gateway and LoRaWAN network server securely. The telemetry system is implemented considering low-cost and open-source hardware and software technologies available on the national market. The results obtained agree with those expected, showing the viability and scalability of the proposed solution.
