Estação meteorológica de baixo custo utilizando arduino.

Abstract

The study of weather atmospheric in a region is importance for defining the climate of this location. With this in mind, the objective of this work was to develop a low-cost meteorological station and install it at the Federal University of Ceará -Campus Russas, as well as collect the data obtained by the project and compare them with the meteorological data provided by INMET (National Institute of Meteorology) of the meteorologicalstation in the cityJaguaruanain Ceará. The platform chosen for the development of this project was the Arduino uno R3 microcontroller and the sensors were DHT11, BMP180 andanemometer SV10. The data collected by the sensors were recorded on a memory card in text format, at the end of each test day the card was removed and the data transfered to Excel. The station tests were donebetween January and February 2021, totaling 13 days. Regarding the analysis and comparison of data from the low-cost weather station with the information provided by INMET, it can be seen that the low-cost station is really a valid proposal, as it showed satisfactory results, since they follow a common trend, emphasizing that as they are low-cost sensors, they have less precision.
