An IoT application for power monitoring system: A case study of 220VAC low voltage load
Abstract
An IoT technology based on Thingspeak cloud is studied in this paper to design a power monitoring system of 220VAC low voltage networks. The hardware unit of this system is designed by using modules including PZEM004T, Wemos D1 R1 Arduino with ESP8266 module. This system can easily measure, acquire and monitor electrical quantities including voltage, current, active power and consumption energy of 220VAC low voltage loads. The system in this paper shows the application of Thingspeak cloud for power monitoring at two different locations of low voltage loads via Internet.
