There can be further up gradations in the project which could lead to a much better system for communication.

Project Report on Laser Torch-Based Voice Transmitter and Receiver | Projects

Electret condenser mic was used during the laser torch based voice transmitter and receiver project report. It can be used in conference halls. Newer Post Older Post Home. Tweet Share Pin it Comment.

You have entered laeer incorrect email address! To avoid 50Hz hum noise in the speaker, keep the photo-transistor away from AC light sources such as bulbs. Provisions have to be made for cases when there is no heavy traffic. EFY was launched inand is counted amongst the leading publications in the fields of electronics and technology—across the globe.

Hi do you have the circuit diagram of laser communication transmitter and wireless laser communication receiver. This not only receives the signal it also demodulates it.

Using this circuit receier can communicate with your own neighbors wirelessly.

Laser Based Transmitter And Receiver

The circuit works perfectly. The main operation of our project is based on the two sections one is laser transmitter section and the other laser receiver section the andd of these two sections constitutes the entire circuit block.


This website is built by the students and is for the students. Automatically changes to Flash or non-Flash embed. You do not have the permission to view this presentation. The transmitter uses 9V power supply. Instead of RF signals, light from a laser torch is used as the carrier in a circuit. Thermal Imaging for Industrial Testing 19 July However, the 3-volt laser torch after removal of its battery can be directly laser torch based voice transmitter and receiver project report to the circuit—with the body of the torch connected to the emitter of BD and the spring-loaded lead protruding from inside the torch to circuit ground.

Narrow beam divergence Laser transmitter and receiver units ensure easy, straightforward systems alignment and long-term stable, service free operation, especially in inaccessible environments, optical wireless systems offer ideal, economical alternative to expensive leased lines for buildings.

Lasers can also transmit through glass, however the physical properties transmittr the glass have to be considered. Automatic Bike Turning Indicator. The reflected sunlight, however, does not cause any problem. VR2 is a volume control for IC2. Is there any specification for the condenser mic used…please reply soon. Diploma Engineer Trainee 27 July The performance characteristics and the practical results verified with real time applications.

Pls reply…Can I use an audio jack instead of condenser mic in transmitter circuit.? Instead of the short range laser, high range lasers can be used which range a few hundred meters. And the total components with their specifications are elaborately explained in this paper. The transistor puts out a signal that is proportional to the light from the LED.

This report involves the study of wireless, open channel communication system using laser a carrier for voice signals. Feed audio signal into transmitter side. Again, we are back with latest project ideas for Mechanical Engineering.

Please reply me soon…. This electronic media starting from satellite communications had invented new dimensions in the field of wireless communication, research in these areas created a new concept of communication by means of lasers, no one ever expected this kind of development in communication strategies and its always a raising question that how we communicate by implementing lasers, in our project we give a detailed answer about how we communicate with others by using laser technology.

In this paper, we study s But the sensor should not directly face the sun. The phototransistor of the receiver must be accurately oriented towards laser torch based voice transmitter and receiver project report laser beam from the torch. If you are not able to think out of box Mechanical Engineering pro IC2 amplifies the signal more and drives the speaker, LS1.
