Development and Calibration of a Low-Cost Electrical Measurement Instrument

Abstract

The most modern technological advances are accompanied by more complex and sophisticated demands of society. Among the main social demands, energy consumption is one of the factors with the highest growth, but technologies related to the theme have not developed at the appropriate pace to the context, especially observing that consumers have little or no information about their consumption data. The wide variety of electronic equipment is evident, therefore, the development of a system that allows the user to monitor the energy consumption of the equipment by only a low-cost sensor and with high precision is an interesting advantage. To this end, it is proposed the implementation of artificial neural networks to increase the accuracy of microcontrolled instrument connected via Wi-Fi, to provide reliable data that can be stored in the cloud and present consumption in real time.
