Design and Implementation of a Smart Meter

This paper presents the design and the implementation of a smart meter for prepaid electricity using an Arduino microcontroller, a global system for mobile communication (GSM) module, and a liquid crystal display (LCD). The smart meter allows users to remotely recharge their meter after purchasing prepaid electricity using a mobile phone. It also allows the meter owner to receive notifications about the level of prepaid credit available in the meter, the meter status, and a threshold for recharge notifications. This paper also discusses the advantages of the proposed system to customers, and the utility company, as well as some of the challenges encountered, and provides recommendations to various stakeholders.
