The study and construction of a low-cost weather station emerged from a scientific initiation project, “Modeling and Analysis of a Wind-Photovoltaic Hybrid System With the Application of a Permanent Magnet Synchronous Generator in Urban Areas,” developed at the Universidade Federal Fluminense (UFF). During the initial stages of this project, there was a need to understand the climate data, which influence the development and proper functioning of wind and photovoltaic systems. However, buying or having access to such measuring equipment requires a high investment. As a result, we sought to collect data related to wind generation and solar photovoltaic energy, such as wind speed, irradiance, temperature, and air humidity, by constructing a low-cost weather station with an Arduino Uno board, electronic sensors, and data storage in a memory card.
