Sistema meteorológico con tecnología IoT para la asignatura de energías renovables

Abstract

Due to the fact that, at the Salesian Polytechnic University South Campus, they have two meteorological centers, one of which is from the Municipality of Quito and the other from the Electrical career, these were used as a guide for the realization of our system. In this degree project, a meteorological system was developed for the subject of renewable energies for the measurement of meteorological variables by means of an IoT architecture. For this, a meteorological station was set up and configured at the Salesian Polytechnic University Block C, where the necessary tests are carried out for the conditioning of the circuits, both for the MCU devices in the control panel and the sensors used. Previously, the sensors were calibrated to obtain a more accurate handling and reception of data. An array of screens was used to monitor, display, and record the meteorological data sent by the MCUS. The NVIDIA Jetson Nano card was used as a machine to establish a connection between the meteorological devices (humidity, temperature, UV radiation and wind speed), for this the programming was carried out in Arduino IDE and Python, establishing an HTTPS server for sending data. For this reason, a database was created in Influx DB by means of SQL code, which manages the filter of data sent by the sensors to be measured. In this project, the comparison of dashboards generated in Grafana and Thing speak was carried out in order to monitor the data received that is sent from the weather station in real time. By means of the Telnet protocol, it is possible to generate a datalogger for the recording of data in a spreadsheet.
