IOT Based Smart Energy Meter for Tariff Calculation,Disconnection and Reconnection of Loads

Abstract

Now a days, every month a person from electricity board visits each and every consumers energy meter for tariff calculation and billing. The main drawback of this system is that person has to go area by area and he has to read the meter of every house and handover the bills. Many times errors like extra bill amount or notification from electric board even though the bills are paid are common errors. To overcome this drawback our proposed project will eliminate the third party between the consumer and service provider, even the errors will be overcome. In this paper, energy meters which are already installed at our houses are not replaced, but a small modification on the already installed meters can change the existing meters into smart meters. The use of Global System for Mobile communication (GSM) module provides a feature of notification through Short Message Service (SMS). One can easily access the meter working through web page that we designed. Current reading with cost can be seen on web page. Automatic ON & OFF of meter is possible. Threshold value setting and sending of notification is the additional task that we are performing. Monitoring and keeping tracking of your electricity consumption for verification is a tedious task today since you need to go to meter reading room and take down readings. Well it is important to know if you are charged accordingly so the need is quite certain. Well we automate the system by allowing users to monitor energy meter readings over the internet. Our proposed system uses energy meter with microcontroller system to monitor energy usage using a meter. The meter is used to monitor units consumed and transmit the units as well as cost charged over the internet using wifi connection. This allows user to easily check the energy usage along with the cost charged online using a simple web application. Thus the energy meter monitoring system allows user to effectively monitor electricity meter readings and check the billing online with ease. It has been further extended by adding an additional feature of tripping the supply to a particular customer in case bill is not paid. The tariff changes can also be easily updated by the EB when needed.
