The idea of the Microcontroller-Based Smart Energy Meter with Anti-Tampering is to create a device that allows people to monitor their electricity consumption accurately and conveniently while also improving the security of the meter. The PZEM-004T sensor was used to measure the electrical parameters, including voltage, current, power, energy, frequency, and power factor, which were acquired by the ESP32 microcontroller and displayed on the OLED display. An IR sensor was used to detect any unauthorized tampering and, when triggered, the ESP32 microcontroller sounded a buzzer alarm and controlled the relay and solenoid lock. The presented system was designed to reduce the effort required for meter reading and provide information about the energy consumption in real-time while also featuring a basic level of protection from tampering. This document has been created for research and educational purposes to illustrate the work of a microcontroller-based intelligent energy meter with anti-tampering features.
