1. SYNOPSIS
INTRODUCTION
This project avoids normal means of measuring the readings using analog
meter and manual amount calculation. The project reduces manual work greatly
and also the human errors made while taking readings and calculating the
amount. All these works done by the microcontroller and data is transmitted
through power line communication.
OBJECTIVE OF THE PROJECT
The project aims at modifying existing energy monitoring and billing
system. The core motive is to automotive the entire system by supplementing a
microcontroller [PIC16F877A] to the energy meter there by minimizing the
modification required and hence increasing the practical viability of the entire
project.
SCOPE OF THE PROJECT
The reason behind the work done was to propose a scheme that would
appear lucrative to all strata of society. The currently existing method for
monitoring the electricity consumption involves a lengthy process of assigning a
person with the duty noting the consumption reading on the meter and submitting
the same to billing department. The bill is generated accordingly. The consumer
goes to the electricity board’s office and stands in lengthy queues in order to pay
the bill.
BRIEF METHODOLOGY
The project uses power line communication for transferring data to the
exchange, a microcontroller unit fitted in consumption area monitors the power
consumed by the user and transfers to the EB office through power line with the
help of interfacing circuits. A microcontroller in the office receives the data
decodes it and sends the value to the LCD where the data is displayed.

2. ADVANTAGES:
1. No separate network is needed since data is transferred through the same
power line.
2. Energy saving will be higher.
3. Fully automated process no manual involvement is needed.
4. Accuracy and Speed of operation will be higher.
5. Can be Implemented in different areas like Houses,Aparments,Lodges
etc.,
6. The cost spent on energy will be reduced.
APPLICATION:
1. Used for commercial measurement of Electricity Consumption.
2. In heavy industries can be used for data communication.

4. PIC16F877A:
The microcontroller used here is an 8 bit RISC architecture
PIC16F877A which has a inbuilt 10 bit ADC, the controller receives the analog
signals from the amplifier with the help of ADC converts to digital and process it.
The microcontroller receiver the data from the RF receiver and process its and
displays in LCD Display.
PULSE SENSOR:
The sensor used to get pulses from the existing meter, for each
rotation, it gives a pulse out, the pulse is counted by using a microcontroller.
RF TX and RF RX:
The EB reading signal send to the microcontroller is transmitted to
control room through this RF transmitters, a code is generated by the controller
and transmitted, the RF receiver receives the signals and sends to another
microcontroller where the code is decoded and its display in LCD display.
LCD:
The LCD is used as output device, the meter readings, the
recharge amount, user id are displayed in this LCD. a 16x2 LCD is used here,
the display is refreshed by the microcontroller.
