MONITORAMENTO ELETRÔNICO DE BAIXO CUSTO PARA MENSURAR GRANDEZAS ELÉTRICAS E CONSUMO ENERGÉTICO

DOI: 10.14684/intertech.13.2014.372-373 This work presents the development of the prototype of a device that monitors electrical quantities that are found in three-phase grid. The prototype allows the mesurement of current, voltage, consumption, energy demand, temperature and final cost in real time. It is totally based on the ATmega1280 microcontroller, a platform for teaching programming with didactic electronics kit. Besides this microcontroller, voltage, electrical current and temperature sensors were used to obtain the best result. Key words - Three-phase Monitoring, Sensors, ATmega1280
