CHAPTER ONE 1.0 INTRODUCTION Current trends in electric energy generation are moving towards the utilization of the environment friendly sources of energy, represented by the wind and solar energy ones as a supplementary energy resource. The solar based one is the more attractive because it is characterized by being free, incur no fuel cost, abundant, limits less, distributed all over the world, pollution free, and require little maintenance. Maximizing power output from a solar system is desirable

very much useful when designing the PCB. Fig 3.4 application diagram The above Fig 3.4 shows the application diagram of the accelerometer. This is very useful because this is will show how the accelerometer needs to be connected in the electrical circuit. We need to be very careful while choosing the coupling capacitors. And also there should not be any component placed with less the 5mm from the accelerometer chip. We need to fallow all these guide lines very strictly. Table 3.1 Pin description

TRANSMITTER AND RECEIVER Using this circuit you can communicate with your neighbors wirelessly. Instead of RF signals, light from a laser torch is used as the carrier in the circuit. The laser torch can transmit light up to a distance of about 500 meters. The phototransistor of the receiver must be accurately oriented towards the laser beam from the torch. If there is any obstruction in the path of the laser beam, no sound will be heard from the receiver. The transmitter circuit comprises condenser microphone

Office Automation Systems Office Automation Systems Office Automation Systems are systems that try to improve the productivity of employees who need to process data and information. Perhaps the best example is the wide range of software systems that exist to improve the productivity of employees working in an office (e.g., Microsoft Office XP) or systems that allow employees to work from home or although on the move. OAS considered also as computer-based information system that

Identification uses radio signals for its function. They operate using a system that contains an antenna and a transceiver to read the radio frequency and transfer the information to the reader and a RF tag. The antenna offers the means for the integrated circuit to broadcast the information to the reader that converts the radio waves, which is reflected reversed from the RFID tag. This digital information is passed on to computers that will evaluate the data sent. Active RFID tags come with a battery that
