smart-energy-meter

This project involves the development of a Smart Energy Meter using an ESP32 microcontroller, a PZEM-004T energy monitoring sensor, a relay, and a web server. The system is designed to provide real-time monitoring and control of electrical energy consumption. The ESP32 collects data from the PZEM-004T sensor, which measures voltage, current, power, and energy consumption. This data is then sent to a web server, where users can remotely access and monitor their energy usage through a user-friendly interface. Additionally, the relay allows for remote control of connected electrical appliances, enabling users to reduce their energy consumption efficiently.
