IoT-Enabled Energy Meter for Smart Home Monitoring and Control

This research introduces an IoT enabled energy meter that facilitates intelligent monitoring of household appliances, permitting users to observe and regulate their energy usage in real-time. The system employs an Arduino Uno microcontroller for data processing, alongside sensors such as the voltage sensor (ZMPT101B) and the current sensor (ACS712) to detect AC voltage and current flow, delivering precise and comprehensive power usage statistics for each device. The data is subsequently communicated through NodeMCU, a WiFi-enabled microcontroller, utilising IoT connectivity to a mobile or web application, thereby providing customers with convenient access to monitor household power use and remotely operate their appliances. This method conserves energy, diminishes power expenses, and facilitates automatic management of idle equipment, hence enhancing energy efficiency in smart homes
