Abstract: This paper presents the design and implementation of a Monthly Electricity Billing Display System integrated with SMS features. The system provides real-time usage information to consumers and sends periodic billing updates via SMS. This not only enhances transparency but also enables users to monitor and manage their electricity consumption efficiently. The increasing demand for energy-efficient and user-friendly solutions in the power sector has led to the development of smart billing systems. This project presents a Monthly Electricity Billing Display System with SMS Feature, designed to automate and simplify the process of energy monitoring and billing. The system continuously monitors the electricity consumption using a digital energy meter and displays the consumed units and billing amount on an LCD screen. A microcontroller processes the data and sends the billing information to the consumer's mobile phone via a GSM module. This real-time SMS alert system enhances billing transparency, reduces manual effort, and helps users stay informed about their energy usage. The proposed system not only improves efficiency for utility providers but also promotes energy awareness and timely bill payments among consumers. It is a step toward smart energy management in line with modern digital infrastructure.
