The proposed method describes Arduino based design and implementation of energy meter using IoT and GSM techniques. In this method, consumers can monitor the energy consumption in units from a web page by providing IP address. Theft detector unit connected to energy meter can inform client aspect once meter meddling happens in energy meter and it will send theft detection information to web page through the Ethernet shield and also to the line worker through GSM. By using this method, power theft can be minimized and the consumer can pay the amount for which power consumed by them. It avoids the excess amount paid by the consumer and human involvement in electrical maintenance.
