Uma Avaliação Experimental de Tecnologias de Comunicação Sem Fio de Baixo Custo para uma Aplicação IoT de Medição Pluviométrica

Meteorological stations constantly monitor the climate using sensors to collect data that allow developing an adequate plan for the ordering and planning of city areas. Usually, collected data is transferred to the data center manually or using cellular or satellite networks, which increases the operating cost of the system. Thus, it is necessary to develop a meteorological station that is low-cost and independent of outsourced infrastructure for data transmission. This paper compares the use of two low-cost wireless communication technologies, Wi-Fi and LoRa, and proposes a hybrid architecture for a rain monitoring application. The results show that technologies play different roles in the architecture, as Wi-Fi provides higher bandwidth over a short distance, while LoRa provides resilient communication over a long distance.
