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

Manuscript Template Copyright Transfer Form. The mic is the audio input. Please enter your comment! C5 couples this audio to T4 and T5 which amplify the signal. This not only receives the signal it also demodulates it. The transistor puts out a signal that is proportional to the light from the LED.

Other than this I am not even sure whether the mic is peaking up the sound or the transmission is happening or the receivsr is working properly. Print Email To A Friend. Its our humble request to all the researchers to go and check the laser torch based voice transmitter and receiver full report method of article submission on below repport But I wish to know more about its design and concepts.

EFY transmittrr launched inand is counted amongst the leading publications in the fields of electronics and technology—across the globe. The phototransistor of the receiver must be accurately oriented towards the laser beam from the torch.

Laser Based Transmitter And Receiver

Diploma Engineer Trainee 27 July The gain of the op-amp can be controlled with the help of 1-mega-ohm potmeter VR1. I have made this circuit but all I can observe is a noise at the receiver speaker. Just keep the phototransistor oriented baxed the remote transmitters beam.

Query is not clear. Hello Researchers, you can now keep in touch with recent developments in the research as well as review areas through our new blog.

Automatic Bike Turning Indicator. The transmitter uses 9V power supply. We have started accepting articles by online means directly through website.

Kindly check it and then prepare article Click Here. Transmittter of RF signals, light from a laser torch is used as the carrier in a circuit. I am using a condenser mic.

Laser Based Transmitter & Receiver | Detailed Project Available

This circuit works perfectly with all the components as specified. The future scope for the laser based communication is to achieve the two way laser communication in spatial communications. My transmitter laser torch not glow what is the fault…?

The phototransistor is kept away from AC light sources such as bulbs. The transmitter circuit Fig.

What should be torcn exact output of the circuit. The circuit works perfectly. Thermal Imaging for Industrial Testing 19 July The laser torch can transmit light up to a distance of about meters.


Voice Transmitter, Laser torch, Photo transistor Abstract In this paper we designed the circuit, using that circuit we can communicate with our neighbors wirelessly. Hello Researcher, we are happy to announce that now you can check the status of your paper right from the website instead of calling us. The main operation of our project is based on the two sections one is laser transmitter section and the other laser receiver section the combination of these two sections constitutes the entire circuit block.

Editorial Board Join as Reviewer. Excitons to Take Electronics into the Future 27 July All Time Fav Videos! T3 is a photo sensitive transistor which receives the laser from the LED transmitter. I am using a laser torch and when it is pointed to the base terminal of the 2n photo transistor a sound can be heard. IC2 amplifies the signal more and drives the speaker, LS1. Transmit the audio signal wirelessly using Laser torch. The receiver circuit uses an NPN phototransistor as the light sensor is followed znd a two-stage transistor preamplifier and LMbased audio Power amplifier.
