Diseño y construcción de un sistema de aquisición, procesamiento y visualización de datos para el análisis de la radiación UV. Casos de estudio: Azogues

Abstract

The purpose of this present investigation is to expound the design - construction and implementation of a data acquisition system which allows analyzing the Ultra Violet (UV) radiation emitted by the sun over the city-Azogues, as well as visualize it by means of using a visual indicator (solar-tra c light). In order to monitor the solar activity in an arranged period of time, from 7:00 am to 19:00 pm, a system which consists of a Zopt2201 radiation sensor is used. This settled period of time is controlled by using a RTC clock module that is synchronized with an Arduino microcontroller, which is the brain of the process. The obtained data is stored in a micro SD memory in a text le. Once the monitored index data has been obtained, the microcontroller activates itself the accurate light indicator according to the color scale established by the World Health Organization (WHO). For six months in a roll the solar radiation has been monitored, an analysis of the variations that the UV index showed throughout the day with a time interval of ve minutes between each sample is done, as well as the average of the data collected in every single month respectively, these variations are being represented using graphs of sequential values. The process of the designing detail, construction, implementation and outcomes are presented in the content of this document and in the respective Annexes that prove the process carried out and the data acquisition as reliable. Finally, the conclusions, recommendations and future work are presented, the prior one being one of the most important aspects, thus being recommended the continuance of the present project either short or long term, with all the aforementioned, the achievement of the proposed objectives is clear.
