Utilização da Plataforma Arduino para instrumentação de um coletor solar aquecedor de ar

Abstract

One of the alternatives for reducing the consumption of electricity in homes and industries that require heating of air is to use solar energy. The Sun is energy source that has been exploited increasingly for the heating of fluids such as water and air. The technology used by solar collector for heating fluids already is well studied and widely used in scientific community, and many studies have been developed in this area. This present work carried out the instrumentation of a solar collector plan designed to work as an air heater. The instrumentation consisted of the installation of temperature sensors connected to a platform of open source code. It was built a solar collector for experimental assembly. Were used tools for easy purchase for any student, hardware and software, low cost and easy access as the sensor LM35 and Microsoft Excel, and free as Arduino and PLX-DAQ. To improve the quality and accuracy of measured signals were constructed two filters, a digital and a physical one
