1. INTRODUCTION
Nowadays the electricity demand is increasing at a constant
rate due to the population and it is being utilized for various
purposes. So, it is becoming more complicated to maintain
electricity and requirements. Also, other issues like power
theft which causes economic loss to the nation. Monitoring
the Optimized power usage and reduction of powerwastage
are the major objectives that lie ahead for a better system.
If the consumer is not available, the billing process will be
pending and the human operator again needs to revisit. It
becomes very difficult, especially in the rainy season. If any
consumer did not pay the bill, the operator needs to go to
their houses to disconnect the power supply. Moreover, the
manual operator cannot find the unauthorized connections
or malpractices carried out by the consumer.Theinaccuracy
and inefficient problem may arise in the billing system.
2. EXISTING SYSTEM
In the existing system for collection of energy consumption
data, the representatives of TNEB monthly comes and visit
every residential, take the snapshot and corporate and
manually reads the consumption data from the meter. This
collected data is recorded on a piece of paper along with a
snapshot of the meter and finally submitted to the local
Tamil Nadu Electricity Board office. Thereafter the officials
read the snapshot and meter readings and then gives it to
the local software for bill calculations and generation of bill.
According to the received bill payment is done by the
consumer. The information can be exchanged fast, secured
and accurate by the means of wireless system. The data
about the energy consumption from residential as well as
corporate zones will be collected by the system and sent
directly to the central server for the preparation of bills.
3. PROPOSED METHOD
Our Proposed System, makes use of intelligently monitored
power consumption data through the monitoring
subsystems. It can detect the abnormality in energy
consumption and Can also find out power theft. Let us
consider we have obtained the fixed rate of units from the
transformer and then that will be split into separate units
(Houses).In case ofanymismatchariseswhilecalculatingthe
unit rate from main supply(Transformer) to separate unit
(Home unit) we can able to easily know about the power
theft. The rate of usage will be displayed by using LCD. If an
area suffered by Power shut down problem then each and
every unit get an alert SMS by using GSM. If the user fails to
make a payment for usage of the Current rate within a
deadline, automatically power supply goes on a particular
home will be OFF Mode. Only after making the payment, the
power supply will be ON. If we supposed to fix the default
unit to separate units, for example, each unit is fixed with
2500Watts and when it reaches 2000Watts it gets an alert
SMS. And then, automatically the flow of power will be
terminated.
4. OBJECTIVE
To provide automated load energy reading on an immediate
basis. To use the electricity in an effective manner. Reduce
the power wastage. A more reliable and accurate reading
value of energy can be collected. Power theft can beavoided.
The problem which arises in the electricity bills can be
minimized. It reduces the manual involvement. The energy
costs/waste without affecting production and qualitycanbe
minimized.

Node MCU is an IOT based open-source platform. The main
advantage is the low cost. It is a widely used wi-fi module. It
will be more simple and powerful. Wi-fi
connection can be established even by small coding withthe
help of node MCU. It even connects wi-fi to the single-chip
devices.

 Operating system: XTOS
 Storage: 4MBytes
 CPU: ESP8266(LX106)
 Power: USB
5.2 CURENT SENSOR
Fig 4-Current Sensor
A current sensor is a device that is used to detect the
electric current (AC or DC) in a wire. It generates an
electrical signal proportional to it. The form of
generated signal could be analog voltage or current or
even digital output which can be utilized to display the
measured current in an ammeter or further analysis in
a data acquisition system the stored signal can be used
or can also be utilized for control purposes. In this
system, we are using the current sensor to find how
much current has been consumed.
The sensed current and the output signal can be:
 Analog output,
 Bipolar output,
 Unipolar output.
5.3 LIQUID CRYSTAL DISPLAY
Fig 5- LCD Display

Liquid crystal cell displays (LCD) are used to display both
numeric and alphanumeric characters which are
represented in dot matrix and segmental displays. LCD is
common because it is more advantages over other display
technologies. Less power is consumed by the LCD than LED
and gas-display displays because instead of working on the
principle of emitting light they work on the principle of
blocking light. A passive matrix or an active matrix display
grid can be used to make LCD. An active matrix requires less
current to control the luminance of a pixel and has a
transistor located at each pixel intersection. For this reason,
the screen refresh time can be improvedbyswitchingonand
off the active matrix display more frequently. Passivematrix
LCDs have dual scanning, which scans the grid twice the
current. In this system, it displays the currentconsumed and
the cost.
5.4 RELAY
Fig 6- Relay
Relays are simple switches that can be operated both
electrically and mechanically. Relays are made up of
electromagnets and a set of contacts. Relay acts as a switch
between load and NodeMCU. The electromagnet is used for
switching mechanism. There are other operating principles
for working, but they differ based on theirapplications.Most
of the devices possess the application of relays. The Relay is
used where only a low-power signal controls the entire
circuit and also used in places where only one signal can be
used to control a lot of circuits. In our proposed system the
relay gets energized by the Arduino UNO. It will play a
central role in efficient energy management and consuming
no power when not in use.

5.5. GSM MODEM
Fig 8- GSM Modem
This GSM Modem can accept any kind of GSM network
operator SIM card and acts similarly to mobile phones with
its unique phone number. Communicationanddevelopment
of embedded applications can be carried out using its RS232
port. Applications includeSMSControl,data transfer,remote
control, and logging can be developed easily. It can be
connected to the PC serial port directly or to any
microcontroller through MAX232. It can be usedtosendand
receive SMS and also to make/receive voice calls. For
applications like data logging and control, it can be used in
GPRS mode. In GPRS mode you can also connect to any
remote FTP server thereby uploading the files for data
logging.
5.6 UART PROTOCOL
The Universal Asynchronous Receiver/Transmitter (UART)
controller is the main component of the serial
communications of a computer. In most microcontrollers, it
is a common integrated feature. The UART converts the
bytes of data into individual bits in a sequential fashion. At
the destination, a second UART converts the bits into
complete bytes. Serial transmission of digital information
(bits) is much more cost-effectivethanparallel transmission.
Communication can be either “full-duplex” (both send and
receive at the same time) or “half-duplex” (devices take
turns transmitting and receiving). One of the best things
about UART is that it uses only two wires to transmit data
between devices. The advantages of UART includes Noclock
signal. Has a parity bit for error checking. The structure of
the data packet can be changed as long as both sides. It is
documented and widely used method.
5.7 ARDUINO IDE
The Arduino Integrated Development Environment or
Arduino Software (IDE) is used to inscribe the code and
upload it to the microcontroller board. It has a texteditorfor
writing code, a message area, a text console, a toolbar with
buttons for common functions and a series of menus. It
intersects with the ArduinoandGenuinohardwaretoupload
programs and communicate with them. Programs written
using Arduino Software (IDE) are called sketches. These

sketches are written in the text editor and savedwiththefile
extension. ino.
6. METHODOLOGY
When the power supply is on, the relay gets energizedbythe
Arduino UNO. Due to this the relaygetsclosedandmakesthe
power to flow through the circuit where the bulb glows. The
current sensor will sense the amount of powerconsumedby
the AC load (Bulb). The resistor can also be used to resistthe
flow of high power. The LCD will display the amount of
current consumed and its corresponding cost. The GSM
module id used to notify the user about the data being
collected which is connected to the Arduino UNO through
UART protocol.
The WI-FI module is connected to the Arduino which helps
to access the Bylnk. Where Bylnk is a mobile application
used on the server-side by the operator. Whenever the user
fails to pay their respective current bill theoperatorcanturn
the power OFF through that mobile application directly
without visiting the corresponding home using the
customer’s id. The power will go off only in that particular
house.
When the fixed power mismatches with the total consumed
power so that the power theft can be easily detected and
notified by this system. Thus, power leakage canbereduced.
The manual operator cannot find the unauthorized
connections or malpractices carried out by the consumer to
reduce or stop the meter reading/power supply that cannot
be identified by the manual operator. Where this systemcan
be used to detect the errors and malpractices caused by
humans.

9. CONCLUSION
In case of any mismatch arises while calculatingtheunitrate
from the main supply (Transformer) to separateunit(Home
unit) means we can able to easily know about the power
theft. The rate of usage will be displayed by using LCD. If an
area suffered by Power shut down problem then every unit
get an alert SMS by using GSM. If the user fails to make a
payment for usage of the Current rate within a deadline
means automatically power supply goes on the particular
home will be OFF Mode after making a payment only the
power supply will be ON. There will be no involvement of
manual operators. Sometimes, the readings obtained by the
manual operator can be inaccurate which can be minimized
by this system. All the malpracticescausedbyhumanscanbe
reduced.
