Manisha Tejwani, Prachi Rane, Moin Syed, Oyesh Patel, Pragyan Pandey Abstract: Paper introduces a system which provides a platform for a consumer to monitor the meter reading via “ThingSpeak” and control the energy consumption, it will also support in keeping the track of energy meter billing. This system helps us to reduce turmoil’s and energy related dissent. The system is implemented using Atmega328P microcontroller and ESP8266 Wi-Fi module. This system do not require the replacement of the energy meter but we associate this system with the installed energy meter that benefit the consumer, the base for designing and implementation of a system is IoT (Internet of Things). The instantaneous data will be fetched from the meter and uploaded on the ‘ThingSpeak’ IoT cloud platform. Keywords: ATMEGA328P microcontroller, ESP8266 Wi-Fi module, Energy Mete, ThingSpeak. I. INTRODUCTION To measure the amount of energy consumed by domestic, commercial and industrial user, energy meter is being used. As the population of energy consumers are gradually increasing the smart energy meter helps to ease the energy management system. The paper depicts the solution for reducing human involvement in energy management for the domestic and industrial consumers. All the data monitoring is done via a web based portal provided with a dedicated internet connection. The system has to be made in such a way that the power consumption is analysed properly. Currently the system we use required human involvement which leads to the time consumption also, it has always been a necessity that a particular individual or person from the energy department should visit the consumer house and note down the readings and therefore errors can get introduced .So in order to overcome the stress, smart energy meter is introduced. In this work, the system uses Atmega328p microcontroller because it is energy efficient hence it consumes less power. The system will combine with the energy meter which is already installed in place of residence. Revised Manuscript Received on March 30, 2020.

The distribution companies are unable to keep track of the changing maximum demand of consumers due to this consumer is facing problems like receiving due bills for the bills that have already been paid. So to overcome these problems the remedy is to keep track of the consumers load on timely basis, which will help to assure accurate billing, track maximum demand and to detect threshold value. By considering the present scenario it is important to build an efficient energy meter. The present project “IoT Based Smart Energy Meter Billing and Monitoring System” addresses the problem faced by both the consumers and the distribution companies. This system make it easier for the electricity department to read the meter readings monthly without a labour work. This can be achieved by the use of Atmega328p unit that continuously monitor and records the energy meter reading in its memory location. The consumers can continuously record the reading and the live meter reading can be access to the consumer on request. II. LITERATURE SURVEY The basic idea is to get an appropriate reading from the energy meter through the SMS service by a GSM module is implemented by Rahman [1]. The system presents the update module in which SMS service is replaced by the Wi- Fi module so that it includes even more features with the help of internet also system provides more flexibility to the consumers to revote his/her conventional post-paid meter to work as a prepaid one presented by Rahul Rajesh B, Mohan Kumar S, Nayab Z Sharief [2]. The system presented by Karthikeyan S, Bhuvaneswari P.T.V is cost effective as it requires a simple upgrade on the existing meters than complete replacement because it is light weight and compact due to SoC for control and communication, the basic idea is too strengthened and also to enhance performance of an Energy Meter [3]. Modern day smart grid technology relies heavily on communication networks for two-way communication between load, generation, transmission, and control center so considering this an advanced metering infrastructures (AMI) is used in this system, proposed by Saikat Saha, Swagata Mondal [4]. III. SYSTEM DESIGN The design of the system includes power supply, Atemga328p Micro-controller, Esp8266 Wi-Fi module, Relay, Switch, LCD display. The load is driven by the relay which is connected to the Atemga328p and an Energy Meter, Wi-Fi modems to introduce ‘Smart’ concept.
