Digital Energy Management for Houses and Small Industries Based on a Low-cost Hardware

The aim of this study is to propose a low-cost tool for monitoring energy consumption in household equipment in a home or small business, based on the Arduino platform for data acquisition, the Open Source Software ScadaBR for the supervision of data in computer and communication of data over the mains with the PLC (Powerline Communication) technology in standard HomePlug AV2. The proposed tool allows them to be identified the highest demands of energy consumption in a home or small business with consumption reduction goal or assist in the implementation of alternative energy sources. It is necessary to first meet the main demands for the further planning of actions, such as the replacement of equipment, maintenance or withdrawal. In this work, the measurement tool is presented, and its operation in conjunction with the supervision software and the main results obtained.
