Utilización de la minicomputadora raspberry pi para la adquisición y evaluación de datos de niveles de radiación solar

Abstract

This paper presents the construction of an electronic prototype that acquires levels of solar radiation, built with a solar cell BPW34, a microcontroller PIC16F88 PIC, Raspberry Pi minicomputer and interaction with other technologies in this case software like Php- MySQL, Raspbian, Apache, Wiring IP and Rrdtool. The analog data is captured by the solar cell and is converted to digital by the PIC16F88 and sent to a database on the Raspberry PI memory, these data information are processed and displayed in HTML graphical format making it accessible from anywhere using a link over internet to review the historical and / or current information online. With this information available worldwide, organizations, academic institutes and interested persons are capable of determining the benefit or harmfulness in Guayaquil. Worth stating are studies of solar radiation that considerer the equator line latitude 0 exposed to high levels of solar radiation, Ecuador being one of the most affected countries.
