Desarrollo de un sistema de detección del nivel de radiación UV dentro de invernaderos agrícolas :desarrollo e implementación de un sistema de procesamiento análisis e interpretación los datos obtenidos en un prototipo UV.

Abstract

This document details the design, development and implementation of a graphical interface to acquire data from a USB 4000-UV-VIS-ES spectrometer with the goal to analyze the quality of UV filters in agricultural greenhouses. The equipment with the humane machine interface-HMI has the ability to acquire a first reference spectra and the spectra with the plastic in order to superimpose the curves and thus to compare the difference of both; in addition, the HMI can show relevant parameters such as plastic thickness, attenuation coefficient, among others. For the development of the interface, the acquired data must be processed, passing through a digital filter and the appropriate mathematical calculations with the aim of a data acquisition, calculation and processing tool. As for results, field data taken in the greenhouses of “La Universidad de Investigación de Tecnología Experimental Yachay Tech” were obtained, as well as in greenhouses of the Jardín Botánico in Quito. In addition, tests with colored spotlights were carried out, and also with a UV LED along with filters of a certain wavelength where the equipment worked correctly and the data was observed in the HMI, as well as exported in an Excel format file for greater accessibility.
