Prototipação de um sistema de controle de iluminação de baixo custo focado em eficiência energética

Abstract

The visual comfort is directly related with the way that we perceive the ambient around us, affecting the quality of daily activities. However, the maintenance of this comfort is tightly connected with energy consumption. It is fundamental not to compromise the needed luminosity to accomplish a given task just in order to reduce the electricity’s outgoings. Nevertheless, it is necessary to consider that an ambient with many artificial light sources will consume more power. Therefore, this project searched to develop a way of autonomous control to adjust residencies lighting. The proposed system comprises both natural and artificial light sources, considering that visual comfort is not easy to be measured. For the purposes of this work, were used guidelines from Brazilian Standard Lighting (NBR) for Workplaces – NBR ISO/CIE 8995-1. As from this knowledge, an autonomous hardware to control a lighting system based on scenarios was prototyped and impacted, which implies the automatic handling of multiple sets of artificial light sources. On this project it was employed the arduino open source hardware platform, contemplating low cost solutions. The experiment uses a luminosity sensor to measure the light incidence inside the environments to, then, control the illumination on each case. For the system’s evaluation, the data of light incidence on the scenarios were compared to those expressed by NBR ISO/CIE 8995-1, with the obtaining of satisfactory results. Still, it was found that the versatility of arduino platform propitiates the performing of new iterations and enhancements, allowing the connection the lighting control with other devices.
