The purpose of the study is to design a prototype model of an energy meter which has the ability of wireless data transfer such as sending emails and SMS. In the current energy monitoring scenario, manual energy meter monitoring is a cumbersome and tedious process for the electricity boards. It involves huge manpower and higher expenditure for a simple task. Manual energy meter monitoring is highly erroneous and amounts to great losses for both the consumers and the electricity boards. In this conventional technique, losing the bills and delay in the arrival of the official to note down the reading are common affairs. Complete digitalization of bill delivery and transaction processes eliminates such uneventful circumstances. The manual reading method is inefficient to meet the raising power demands. The invention described here has the potential to wipe of manual energy meter reading from the scene and replace it with a sophisticated automated system facilitating remote monitoring of energy consumption. In this proposed system, the Raspberry Pi performs all the essential functions of a microcontroller and supports features like sending emails and SMS with the aid of Wi-Fi dongle and GSM modem. This automated system enables continuous monitoring of energy consumption.
