AVALIAÇÃO DA APLICABILIDADE DO PROTÓTIPO DE RADIÔMETRO UTILIZANDO PLACA FOTOVOLTAICA COMO SENSOR DE RADIAÇÃO

Abstract

This Project is about the development of an equipment capable of measuring the solar radiation level. Throughout the project, the main object was the creation of an efficient and low-cost equipment from electronic board (Arduino) and a solar panel positioned in the same direction and the same height from ground, photovoltaic panel 53 mm x 30 mm. According to the need of attenuate, the sensitivity it was installed a lens capable to retain 95% of radiation, turning the equipment more efficient against random measurements related to incident radiation. The balance of solar radiation captured by the panel was evaluated in correlation with a methodology prior to the present work and validated the data with the Commercial Meteorological Station Davis (model Vantage Vue Pro 2), belonging to experimental farm Procafe's with positioning at the coordinates of latitude 21 ° 33'59,30''S and longitude 45 ° 24'16,69''O. Analyzing the points obtained by the photovoltaic panel, a low coefficient of representativeness was observed. Therefore, it is concluded that the object used as an attenuator has interfered in a negative way to obtain the data.
