ABSTRACT: Accurate measurement of electrical consumption is one of the challenges faced by energy suppliers in managing their electricity networks. To address this issue, this study focuses on the design of a smart electricity meter capable of accurately measuring the electrical parameters of subscribers to enable these suppliers to easily manage their electricity network. The proposed system incorporates voltage and current sensors supplying the value of these parameters to the ESP 32 microcontroller, which in turn induces actions to determine consumption data. The GSM SIM 800 module used transmits this data to a database that can be consulted on the supplier’s desktop GIC application and also enables subscribers to recharge their meters and find out as many times as they like about the electricity consumption status of their installation. The results of real-life tests show that the device accurately measures electrical parameters (in compliance with ISO/CEI 17025: 2017). Customers can also interact with their meter via their mobile phone. All this means that the meter holds great promise in terms of customer satisfaction and supplier autonomy in managing their network.
