This project involves developing a microcontroller-based system to identify electricity theft. It monitors energy usage using current and voltage sensors and displays the readings on an LCD screen. When overload is detected, the system will provide intimation by triggering a buzzer. Implementing this across an entire area network could help the electricity board detect theft more effectively by monitoring for load variations. The system works by using a precision rectifier and amplifier to measure current, a voltage divider for voltage, and a microcontroller to process the data and control the LCD, buzzer, and relays.

IDENTIFICATION
ABSTRACT
Our project is microcontroller based ELECTRICITY theft identification system. .
This project will be very much useful to the EB department to detect the load
variation. This project will monitor the energy in the LCD. And it will give the
intimation when the people who take overload.
If suppose we implement the project for a complete network in an area, that will be
consuming very useful to detect EB theft.
In this project we calculate the energy with current and voltage sensing unit. For
sensing the current we use precision rectifier. Precision rectifier output will be in
millivolt. That will be amplified using amplifier unit. The output of amplifier will be
given to microcontroller unit to sense the current. For sensing the voltage we use
voltage divider circuit. Then the microcontroller will display the energy output in
LCD display.
