Resumo(s)
Giving a background of the importance of Energy Efficiency and Renewable Sources, the present work aims to develop a low-cost smart plug module that could self-manage loads automatically in a residence. The system uses renewable energy by controlling current based on zero-crossing synchronism and switching using a semiconductor TRIAC. On this, the power could be customized according to the device requirements, being controlled remotely and being able to communicate with a supervisory using the Wi-Fi connection and
MQTT publish/subscriber protocol to change data. Thus, it also discusses alternatives to use this surplus energy in the photovoltaic system context, giving highlighting resistive loads which can deal better with the high current and voltage variation due to switching. After test different microncontrollers and reach a final version, it has been made a basic supervisory, especially for tests that contemplate the sending and receiving data.
