Design of IoT-based smart energy meter for e-billing and prepaid electricity

This study focuses on the utilization of an Internet of Things (IoT)-based smart energy meter for the purpose of wirelessly analyzing power usage in electrical systems. The objective is to alleviate the need for manual processing of electricity bills, enhance demand management, facilitate prepaid electricity supply, and reduce instances of power theft. With the escalating demand for electricity, the manual tracking and prevention of power theft pose significant challenges. The Internet of Things (IoT) is employed for the purpose of managing power consumption by consumers, implementing prepaid electricity supply systems, and ensuring the efficient operation of microgrids through the regulation of power generation and demand ratios. In this study, an Internet of Things (IoT)-based smart energy meter is developed utilizing the ESP8266 as a Wi-Fi module, the Arduino Uno as an interface microcontroller, and voltage and current sensors to accurately measure power usage. The collected data is stored and accessed through the ThingSpeak cloud platform. Additionally, a relay is incorporated into the system to regulate power flow for a prepaid system.
