IOT Based Smart Metering and Prepaid Tariff System

Abstract

In present scenario the major problems faced by the electricity distribution company is to curb the issue of non-payment of bills and to reduce the man power for efficient energy management for modernization of industries. Electricity Distribution Company follows a very old procedure of tariff management system, which needs to be changed due to the change in lifestyle and vast application of automation.  From customer point of view, they want to operate all of their equipments remotely. On the other hand, for the distribution company they want to use the smart grid technology for grid controlling and renewable energy module. But this kind of application is impossible to run with the help of a normal energy meter due to human interruption and security reason. To solve this problem a smart energy meter is designed which operate with the help of Internet of Things (IoT) technology by using Arduino UNO, which is interfaced with the SIM GSM 900 (Global system module) for sending message about current status and remaining balance of the energy meter. A liquid crystal display (LCD) is also connected with the module to display the current status of the meter to the consumer. So, a smart energy meter has been designed which is capable to save the data for the future use in a centralized database and retrieve it according to the requirement.
