INTRODUCTION

Power line (A.C mains) communication between devices connected on the same phase.

The interfacing circuitry between the mains and host controller is achieved by ST7538Q transceiver.

PROPOSED SYSTEM

Control room

pipe

Water tank with float sensors

Water tank

Electric pump

BLOCK DIAGRAM

The sensors in the water tank will determine the waterlevel and the microcontroller will send the signals through powerlines to turn on or off the pump.

The relay driver  is necessary to control the pump by a low-power signal.

TRANSMITTER SIDE

When the water level is below a certain level, microcontroller will send a signal through the powerlines to start the pump.

Also when the waterlevel is above a certain limit, a signal will be sent to stop the pump.

RECEIVER SIDE

AC Signal received will be converted to dc by ST7538Q.

Microcontroller will read the signal and accordingly turn the electric pump on or off depending on the instructions received.

CIRCUIT DIAGRAM

SOFTWARE USED

Arduino is used to program the Atmega8 Microcontroller.

The open-source Arduino environment makes it easy to write code and upload it to the i/o board.

It runs on Windows, Mac OS X, and Linux. The environment is written in Java and

based on Processing, avr-gcc, and other open source software.

WORK COMPLETED

Research of existing system Research of data transmission through power

lines Uniting both systems Circuit Diagram Collecting required components

ADVANTAGES

Easy to install as network infrastructure is already present.

Almost fully automated system, so minimal human attention required.

APPLICATIONS

  Home automation

Office automation

Home Broadband internet

Smart Meter Reading

HDTV Networking

Patient Monitoring in the Hospitals

FUTURE SCOPE

This technology can be used to make all devices plug and playable.The only requirement would be a socket.It would also increase communication between devices.
