SYNOPSISINTRODUCTION This project avoids normal means of measuring the readings using analogmeter and manual amount calculation. The project reduces manual work greatlyand also the human errors made while taking readings and calculating theamount. All these works done by the microcontroller and data is transmittedthrough power line communication.OBJECTIVE OF THE PROJECT The project aims at modifying existing energy monitoring and billingsystem. The core motive is to automotive the entire system by supplementing amicrocontroller [PIC16F877A] to the energy meter there by minimizing themodification required and hence increasing the practical viability of the entireproject.SCOPE OF THE PROJECT The reason behind the work done was to propose a scheme that wouldappear lucrative to all strata of society. The currently existing method formonitoring the electricity consumption involves a lengthy process of assigning aperson with the duty noting the consumption reading on the meter and submittingthe same to billing department. The bill is generated accordingly. The consumergoes to the electricity board’s office and stands in lengthy queues in order to paythe bill.BRIEF METHODOLOGY The project uses power line communication for transferring data to theexchange, a microcontroller unit fitted in consumption area monitors the powerconsumed by the user and transfers to the EB office through power line with thehelp of interfacing circuits. A microcontroller in the office receives the datadecodes it and sends the value to the LCD where the data is displayed.
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.

PIC16F877A: The microcontroller used here is an 8 bit RISC architecturePIC16F877A which has a inbuilt 10 bit ADC, the controller receives the analogsignals 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 anddisplays in LCD Display.PULSE SENSOR: The sensor used to get pulses from the existing meter, for eachrotation, 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 tocontrol room through this RF transmitters, a code is generated by the controllerand transmitted, the RF receiver receives the signals and sends to anothermicrocontroller where the code is decoded and its display in LCD display.LCD: The LCD is used as output device, the meter readings, therecharge amount, user id are displayed in this LCD. a 16x2 LCD is used here,the display is refreshed by the microcontroller.
