RESEARCH ON TWO-WAY POWER METERS USING IoT TECHNOLOGY

Abstract

The article presents about two-way energy meter applying IoT technology. The
system model includes an energy meter, a Blynk server, and a computer or
smartphone. The energy meter will base on the value of current, voltage, phase
difference and use time to calculate the value of energy consumed by the load.
Current, voltage, power, frequency, phase difference and power consumption
values are displayed on the LCD. In addition, power consumption data is also sent to
a Wi-Fi module for connection to the Blynk server. When connected to the internet,
the energy meter sends data to the Blynk server. Thanks to Blynk server, when
users want to monitor information about power consumption indicators, they only
need an internet-connected device such as a computer or phone to view it. The
two-way electric meter model has been built and operates stably.
