IOT-based electrical energy counter system using Atmega328 microcontroller and PLC.

Advances in information technology and computers in the Industrial Era 4.0 have been proven to improve organizational performance and organizational operational efficiency. One of the characteristics of the Industrial revolution 4.0 is the use of the Internet of Things (IoT) to obtain data in real time. The system for calculating electrical energy consumed still uses a token-based analog and digital KWH (Kilo Watt Hour) meter. In prepaid electricity, consumers have to spend money or pay first for the electrical energy that will be consumed. However, many people are still reluctant to use this type of electricity. Because one of the disadvantages of using prepaid electricity services is that the electricity will turn off automatically when the credit runs out, so consumers must often monitor the remaining balance. In postpaid electricity, consumers only need to pay for electricity for the amount used and pay the bill on the date that has been set by PLN. However, this postpaid electricity system has the opportunity to harm PLN because this analog system is easy to modify, so that the KWH meter rotates more slowly, even changing / doubling the existing electricity lines without going through the electricity meter. This study tries to propose a system for calculating electrical energy consumed automatically in a closed network by utilizing IoT technology so that it can be monitored in real time. This system will also be useful in anticipating illegal flow theft. [ABSTRACT FROM AUTHOR]
