This document proposes an easy, efficient, and integrated billing system for electricity using smart meters. It involves using an Arduino microcontroller connected to a smart meter and photodiode to remotely read electricity usage data. This data would be sent via the Arduino to an online portal or SMS messages to inform customers of their electricity usage and bills. The system aims to automate the billing process, reduce costs and queues for bill payment, and allow customers to access billing information remotely through a website or mobile notifications. It could help utilities better understand customer usage patterns and reduce non-technical losses like theft.
