Smart Energy Meter

Abstract

Objectives: To present a Smart Energy Meter (SEM) that reduces errors effectively while generating the electricity bill. Methods: This SEM confluence of modern technology and existing electrical architecture, yet it is a low-cost device suitable for the Indian environment. The proposed SEM is only incorporated with a current sensor and other associated circuitry. Findings: A quantitative comparison between our SEM and other existing SEMs revealed that the proposed SEM is superior in the economy, circuit complexity, and accuracy. With mere Indian Rupees (INR) around 3k to 3.5k, it can be designed to be used. There is no complex circuitry associated with this proposed SEM. The accuracy of the proposed SEM is also comparable with the existing meters that it could attain up to 0.7-0.9 % accuracy. Novelty: The proposed system deals with the digitalization of the billing process with the help of sensors that are used to calculate the usage time of each household device. Subsequently, it alerts the user about the consumed units using a GSM (Global System for Mobile Communication) module. An Advanced Reduced Instruction Set Computer Machine (ARM7) microcontroller continuously monitors the system, and the results can be viewed through a built-in Android App. A Wi-Fi module allows for continual data updates and control of home appliances. Achievements: The real-time solution for the overloading problem is provided in this research. Keywords: Smart Energy Meter, GSM module, Relay module, ARM7, Wi­Fi module
