Electrical energy consumption monitoring system in the residential sector using IoT

In Latin America and the Caribbean, the consumption of energy, that comes mainly from fossil resources, have carried an increase in the air pollution. Electricity generation and its consumption in residential sector contributes to this problem with a significant percentage. On the other hand, recent research has demonstrated that the use of smart energy meters in developed countries reduces the electricity consumption due the continuous feedback gave to the consumer. This research presents the developing and implementation of an electrical energy consumption monitoring system based on smart sensors with IoT technology. The system calculates the instant power and the electrical efficiency as well as the energy consumed and its cost. The information of these variables is processed and transferred trough a WIFI ESP8266 module to a ThingSpeak server that works like a cloud database. Also, an Android mobile application that interacts directly with the database was developed to users visualize the variables behavior. For validate the smart sensor accuracy its measures were compared with the measures of an oscilloscope and a multimeter. Relative errors between -2.34 and 1.92 % were observed.
