PROMAS is a research department of the University of Cuenca. This department requires monitoring certain hydro-meteorological parameters using meteorological stations (around 130) distributed in an area of interest, among the parameters is the amount of rain. Measurements are used for research purposes in different projects [1]. The projects contribute to the sustainable management of water and soil resources, through the generation of scientific knowledge, training and extension. The stations have a data logger. The data logger is in charge of collecting the hydro-meteorological parameters. These data require to be transmitted / copied to the PROMAS servers. Currently, PROMAS personnel travel to the stations to download the in-situ data stored at each station. Access to these stations is complicated because they are distributed over a geographically wide area and most of them in places that are difficult to access [1]. The development of prototypes to transmit the collected information in quasi-real time is part of the project ‘’Aplicación de Tecnologías Inalámbricas al Monitoreo Climatológico en la Cuenca del Río Paute”. The technology used to achieve this objective is LoRa and the LoRaWAN protocol [2]. The data logger is one of the prototypes developed. In this work, the design and implementation of a compact PCB pluviometric data logger using surface mount components with LoRa technology is presented. This implementation incorporates the acquisition, storage, and wired and wireless transmission of data. LoRa is one of the LPWAN low consumption and long range network technologies for application in IoT projects and is characterized by its sensitivity, affordable cost and simplicity of implementation. For end-to-end communication it adheres to the LoRaWAN protocol, its architecture is made up of nodes distributed throughout the area of interest, and a device that is a gateway between the nodes and the network server. The data logger has the function of downloading data in-situ using WiFi technology, for this a gateway is used that is wired. The architecture of the system is adapted to 3,3 V in its power supply, to reduce energy consumption. As a result, according to tests carried out, the developed device presented an optimal operation in the acquisition, transmission and storage of data, as well as low energy consumption.

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
