Protótipo de solução IoT para uma estação meteorológica aplicando tecnologia LoRa no ambiente agro

Abstract

The advancement of IoT in the agro environment brought to the scene a new technology called LoRa, which proved to be stimulating to meet the need to cover a large area in the collection of data from a plantation. When faced with this type of problem, solutions are usually costly due to machinery and infrastructure. By deploying a system using LoRaWAN protocol technology, this cost is reduced due to wireless communication and battery power. For this reason, this technology was selected for the development of a prototype of a meteorological station implanted in an agro-environment, in order to study energy expenditure and coverage area. The information captured by the prototype is transmitted via cloud that can be better studied later in order to improve planting performance. During the tests, the system showed promising results, using little energy consumption due to the data transmission methodology of the LoRa chip. As for the communication distance, data can be received at about 4 kilometers, considering an average level of interference from obstacles.
