Abstract. In this paper we designed the circuit, using that circuit we can communicate with our neighbors wirelessly. Instead of RF signals, light from a laser torch. 5 Nov Using this laser based transmitter & receiver circuit you can Instead of RF signals, light from a laser torch is used as the carrier in a circuit. 16 Oct Download Project Report on Laser Torch-Based Voice Transmitter and Receiver. Right from the origin communication system had undergone.

You should get the same audio signal at the output of the receiver side. Saturday, July 28, Useful Raspberry Pi Projects. However, the 3-volt laser torch after removal of its battery can be directly connected 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.

Go transmittee Application Have a question? Design Guides Pmods — How to get started? Memory Design Engineer projech July The mic is the audio input. Newer Post Older Post Home.

Instead of the short range laser, high range lasers laser torch based voice transmitter and receiver project report be used which range a few hundred meters.

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. To avoid repory hum noise in the speaker, keep the photo-transistor away from AC light sources such as bulbs.

Laser Based Transmitter And Receiver

If there is any obstruction in the path of the laser beam, no sound will be heard from the receiver. Automatically changes to Flash or non-Flash embed. Presentation Description No description available.

All the resources in this website are Free of charge. But the sensor should not directly face the sun.

Paper cone moves in accordance with electrical signal. Top 10 Civil Engineering Projects for Students.

Instead of RF signals, light from a laser torch is used as the carrier in a circuit. Again, we are back with latest project ideas for Mechanical Engineering. But I wish to know more about its design and concepts.

Other than this I am not even sure whether the mic is peaking up the sound or the transmission is happening or the receiver is working properly. To minimise the noise please follow the instructions given in the article. The gain of the op-amp can be controlled with the help of 1-mega-ohm laser torch based voice transmitter and receiver project report VR1.

I have made this circuit but all I can observe is a noise at the receiver speaker. Temperature Monitoring on Smartphone. This website is built by the students and is for the students. VR2 is a volume control for IC2.

Thermal Imaging for Industrial Testing 19 July I am using a condenser mic. The transmitter circuit Fig. The laser transmission is very secure because it has a narrow beam.

C5 couples this audio to T4 and T5 which amplify the signal. Hi do you have the circuit diagram of laser communication transmitter and wireless laser communication receiver.

This circuit works perfectly with all the components as specified. Is there any specification for the condenser mic used…please reply soon.

Laser Based Transmitter & Receiver | Detailed Project Available

Hope you will enjoy the FREE projects. The performance characteristics torcb the practical results verified with real time applications. There are no recurring line costs.

Use this report for your study and reference work to make your project. Hello, Welcome to Final Year Projects. Feed audio signal into an side. This report involves the study of wireless, laser torch based voice transmitter and receiver project report channel communication system using laser a carrier for voice signals. Civil engineering is one of the very old and important branch of engineering and help in building great architecture design and deal in mai 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.
