Plataforma Didática para Controle de Vazão e Nível a Partir de Resíduos Eletroeletrônicos

Abstract

Given the current situation of electronic waste (e-waste) production, aiming at reducing costs and development of sustainable laboratory practices, this article proposes a low-cost platform to develop experiments for automation course using e-waste. The practices are about flow and level control, which make up many industrial processes and students have the opportunity to work from the characterization of the sensors used to the controller. The developed platform can be controlled by microcontrollers or industrial programmable logic controllers (PLC) and experiments that were carried out in different subjects are discussed, which demonstrates that the platform can be versatile and flexible, being used in multidisciplinary experiments (which may involve instrumentation, control, data acquisition, human-machine interface, among others). The total cost of the platform was approximately R$104.50 and to evaluate the result, a questionnaire was applied to students who indicated that they had approved the use of the platform. It is expected that this type of solution will be increasingly disseminated to the community.
