Development of Smart Energy Meter for IoT-Enabled Power Monitoring

Existing low-cost smart energy metering systems based on ESP8266 and IoT platforms primarily focus on remote monitoring, while offering limited support for integrated energy analytics, automated billing, threshold-based alerts, and prototype validation across both simulation and hardware environments. To address this gap, this paper presents a cost-effective IoT-enabled smart energy meter that combines real-time electrical parameter monitoring, automated energy consumption analysis, and cloud-based visualization within a unified framework. The proposed system is developed and validated in two stages: (i) a Proteus-based simulation platform incorporating virtual energy measurement and wireless data transmission, and (ii) a hardware prototype implemented using a NodeMCU (ESP8266) module integrated with voltage and current sensing circuits and the Blynk IoT platform. The system continuously measures voltage, current, power, and energy consumption, automatically computes electricity usage and billing information, generates threshold-based consumption alerts, and enables remote monitoring through a mobile application. Unlike conventional smart meter implementations that primarily provide data logging, the proposed prototype integrates energy measurement, billing estimation, warning notifications, and cloud connectivity in a low-cost architecture suitable for residential energy management. Experimental validation demonstrates reliable real-time monitoring and remote accessibility, highlighting the feasibility of the proposed solution as an affordable smart metering platform for IoT-enabled energy management applications.
