This document summarizes an intelligence digital energy meter system that uses an Arduino microcontroller to automatically monitor energy consumption and cut power if bills are unpaid. The system includes current sensors to measure load consumption, a GSM module to send alert messages to users, and relays connected to the Arduino to remotely disconnect power. It aims to reduce losses from unpaid bills by remotely disconnecting power after sending alert messages. The system could help electricity providers better monitor usage and cut down on manual disconnection of unpaid services.

ABSTRACT
Here a lot of customs are used electrical energy
but not pay the bills in time.so here we avoid this problem
by using this project. We can measure the power by each
load and take the information through the mobile by using
GSM module. After the taking alert from the situation the
consumer not respond for emergency alert we can cut –off
the supply to the consumer by automatically.
Keywords— Liquid Cristal Display, GSM, LCD, PSU
I. INTRODUCTION
If any consumer did not pay the bill, the
operation needs to go to their houses to disconnect the
power supply. These processes are time consuming and
difficult to handle. By the system, cut the supply
automatically. The use of Arduino (microcontroller)
there are many improvements in automating various
industrial aspects for reducing manual efforts. Now a
day the number of Electricity consumers is increasing in
great extent. It became a hard task in handling and
minting the power as per the growing requirements.

Power supply is a reference to a source of
electrical power. A device or system that
supplies electrical or other types of energy to an
output load or group of loads is called a power
supply unit or PSU. The term is most
commonly applied to electrical energy supplies,
less often to mechanical ones, and rarely to
others.

The Allegro ACS75x family of current sensors
provides economical and precise solutions for current
sensing in industrial, automotive, commercial, and
communications systems. The device package allows for
easy implementation by the customer. Typical
applications include motor control, load detection and

VI. GSM (GLOBAL SYSTEM FOR
MOBILE COMMUNICATIONS)
GSM (Global System for Mobile
communications) is a cellular network, which means that
mobile phones connect to it by searching for cells in the
immediate vicinity. GSM networks operate in four
different frequency ranges. Most GSM networks operate
in the 900 MHz or 1800 MHz bands. Some countries in
the Americas use the 850 MHz and 1900 MHz bands
because the 900 and 1800 MHz frequency bands were
already allocated.

VII. CONCLUSION
This research paper demonstrates the concept
sand implementation of automatic trip control system for
energy management using Arduino controller and GSM.
It mainly focused on industrial purpose. The similar idea
can be implemented for domestic areas for avoiding the
illegal usage of electricity. This paper is aimed at
reducing the heavy power and revenue losses that occur
due to power theft by the customers. By this design it
can be concluded that power theft can be effectively
curbed by detecting where the power theft occurs and
informing the authorities. Also, an automatic circuit
breaker may be integrated to the unit so as to remotely
cut off the power supply to the house or consumer who
tries to indulge in power theft.
FUTURESCOPE
Though many have tried implementing a
country wide AMRS, it is still an unreachable goal,
many factors like cost, feasibility and mainly the need to
replace the existing system have hindered its
development. At least in near future, the cost involved in
the building of this system could be minimized by using
more efficient technology implemented worldwide.
