Desenvolvimento, Construção e Calibração de Uma Central de Monitoramento de Consumo de Energia Elétrica e de Água Utilizando o Microcontrolador Arduíno.

Abstract

This paper presents the results of the development of instrumentation that enables sufficiently precise measurement of energy and water consumption of a small installation. The proposed prototypes allow the measurement of the electrical power consumed from the grid and the water flow drained from the supply system as functions of time. Through the temporal power and flow curves is possible to obtain, throughout numerical calculation (integration), the consumption of energy and water. Given the social problem created by the energy and water crisis, one of the objectives of the work is to find a shortage of physical measures that permit, at low cost, better management of energy and water conservation actions. Because of the low cost contour and choice of an open source system, we used the Arduino microcontroller. In addition, the objective is the future use of the instruments and their acquired knowledge, as a teaching object in the course of production engineering. In the body are presented: the stages of development, construction details and both sensors calibration methods. The results obtained during the calibration of the sensors indicate an accuracy that is consistent with the measurement needs and proposed objectives.
