Registrador de datos pluviométricos basado en el microcontrolador ATMEL y el transceptor LoRa

Abstract

The water and soil program PROMAS of the University of Cuenca contributes to the sustainable management of water and soil resources. To carry out this task, PROMAS requires, among others, to monitor environmental parameters using meteorological stations. In the present work, a rainfall data logger was developed on a compact printed circuit board (PCB) using surface mount components. LoRaWAN/ LoRa technology is used to transmit the information. LoRa is one of the LPWAN low power, long range network technologies. LoRaWAN is a protocol that manages end-to-end communication. This development integrates the acquisition, storage and transmission of data. The architecture is made up of a gateway device, the network server, and sensor nodes distributed over the area of interest. The data logger has the additional function of downloading data on-site using WiFi technology. The tests carried out showed that the developed prototype worked correctly in the acquisition, transmission and storage of data
