INTRODUCTION:
IR-BASED VOICE TRANSMITTER AND RECEIVER, the aim of the project is to communicate wirelessly. In this project we are using various transistors, LED, op-amp etc. and we made a detailed study on this so as to effectively use them in our project.
OBJECTIVE OF THE PROJECT: -
The aim of the project is to communicate between any 2 distant places wirelessly which are at a distance of 5meters apart. The distance can be improved to even 500meters using Laser light devices. This communication is very much use full when you want to communicate with some one which is very important.
This kind of technology is very much useful in Army and Defence, since their communication is very much crucial.
CIRCUIT DIAGRAM :-
PRINCIPLE OF OPERATION:-
When ever you want to transmit information from one person to another our equipment i.e. transmitter and receiver is very much useful.
You may also think a mobile does the same work, but it charges for every second you talk, our system just works like a walky-talky. As a mobile, you need not press the number whom u need to call, if the other person had this equipment, by just pressing a key you will get connected.
System Features:
• Easy operation
• Convenient
• Affordable
Required Skills:
• Understanding of IC’s
• Understanding op-amps and all
• Design and Fabrication of PCB
Project phase: -
• Schematic design and drawing of PCB
• Preparation of PCB
• Assembling and Testing of Interfacing Circuits
• Project Report
EQUIPMENTS: -
• Printed Circuit Board
• 9volts Power Supply
• IC UA741 and LM386
• Transistors BC547 and BC548
• Resistors and Capacitors
• BD139 Heat Sink
• Mike and Speaker
• 2N5777/L14F1 Photo Transistor
• IR led’s
