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 ST 7538 Q transceiver.
PROPOSED SYSTEM Water tank with float sensors pipe Water tank Control room 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 ST 7538 Q. 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 Atmega 8 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.
