High sensitivity universal lifi receiver for enhance data communication

This paper presents an approach for wireless data communication between two systems through visible light. This approach creates a way which can make data transmission faster than current wireless communication technology. Use of visible light for wireless communication can solve issue of lack of radio wave spectrum space that will increase the data transmission rate. The proposed system demonstrates transmission and reception of data by switching LED on and off at very high intensity which is too fast to be noticed by human eye. We can encode various data by varying the rate at which LEDs flicker and transmit it. This paper describes the design, fabrication, and capabilities of visible light based data communication, as well as the development of the LED and photo sensor based optical wireless communication system. The data is to be send from one PC to another PC using UART serial communication.
