Laser Communicator Reniel Joseph E. Bautista‚ Harris W. Guinomla‚ Jose Paulo Piloton and Khevin Anne A. Francisco‚ EECE‚ MSU-IIT Abstract –This project involves discovering how wireless connections occur in the atmosphere using a beam of laser. The project‚ laser communicator‚ uses electromagnetic waves to transfer information without direct connection between the input and output devices. This project will also investigate how the sound waves are transmitted as electrical and light signals through

consists of‚ a transmitter and a receiver. Therefore two mobile phones are required for effective transmission and reception by DTMF .The robot is controlled by the mobile phone held by the user‚ which communicates with the mobile phone attached to the robot. In the course of a phone call‚ if any button is pressed‚ a tone corresponding to the button pressed is heard at the receiver end‚ which is called ‘Dual Tone Multiple frequency’ (DTMF) tone. The robot receives these tones via the receiver mobile phone

Transmission Media • Transmission medium – Physical path between transmitter and receiver – May be guided (wired) or unguided (wireless) – Communication achieved by using em waves • Characteristics and quality of data transmission – Dependent on characteristics of medium and signal – Guided medium ∗ Medium is more important in setting transmission parameters – Unguided medium ∗ Bandwidth of the signal produced by transmitting antenna is important in setting transmission parameters ∗ Signal directionality

chapter 1 introduction 1.1GENERAL With the increasing denial of time and space the RFID technology is gaining momentum day by day. RFID is a source of identification of individuals and unique products. The budding technology RFID proves to threaten even the cloning technique‚ through the chip insertion. New ways of improving the existing RFID technology are being found and implemented. This advancement of RFID technology is looked beyond the security purposes. 1.2 PRESENT SCENARIO

Signal amplification circuit The ultrasonic signal which was received with the reception sensor is amplified by 1000 times(60dB) of voltage with the operational amplifier with two stages. It is 100 times at the first stage (40dB) and 10 times (20dB) at the next stage. As for the dB (decibel)‚ refer to "Logarithm Table". Generally‚ the positive and the negative power supply are used for the operational amplifier. The circuit this time works with the single power supply of +9 V. Therefore‚ for the
