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

Abstract

The noticeable rise in electricity bills is one of the most major factors leading to an economic crisis for all parts of the world today. It causes many negative impacts on the economic lifestyle of society. This is due to the depletion of unnecessary energy which leads to financial losses for customers. Moreover, it leads to problems between customers and electric companies. Day by day, electricity bills increase further due to the increase in the number of electrical appliances, which in turn leads to an increase in the daily use of electricity. The absence of an energy consumption monitoring system exacerbates this problem. Therefore, it became necessary to develop a system to monitor energy consumption that can calculate daily consumption and display it to customers so that they can know their energy consumption without facing any difficulties. 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.
