Design and Implementation of an Energy Meter System for Optimized Cost using Internet of Things (IOT) Technology

This paper aims to design and implement an energy meter system for optimized cost using internet of things (IOT) technology. This is to alert customers to take preventive measures that help limit the rise in electricity bills. The main components of system design are Node MCU, Arduino Uno (Atmega 328) Microcontroller, AC Fan, AC Light Bulb, LCD I2C (20x4) and ACS712 Current Sensor, which is responsible for sensing the current of electrical appliances. This system was simulated through the TINKERCAD program, as for the system programming, it was done through the Arduino Integrated Development Environment (IDE). Moreover, the system implementation and testing has been successfully completed, and the required results have been analyzed and successfully reached. The system has performed well and is acceptable, also it can be classified as efficient, simple and easy to use
