Abstract

Light has been around for millions of years. It has created us, has created life and has created all stuffs of life. WiFi has become indispensible part of our daily life. We can't imagine life without these, be it at home, at work place, meeting hall, hospitals, aircrafts, street lights, vehicles, traffic lights and so on. In recent years, the rapid development in solid state Light emitting diodes(LED's) material has given rise to next generation 5G data communication called LiFi it is faster in transmission of data, more secure and immune to EMI relative to radio waves unlike radio waves. This paper presents a implementation of LiFi system, how its different, different application scenarios and a prototype is been developed to demonstrate the implementation of LiFi in industrial automation system for device switching and audio transmission system. The Design is accomplished using Optocoupler, PC and serial interface along with LiFi transmitter an LED, LiFi receiver solar panel, the LED light is modulated with data signal, converted to binary form in order to support transmission over light, on and off modulation is used and the signal is received at receiver side by a photo detector i.e. solar panel, given to MCU received signal is demodulated to get back original transmitted data and corresponding devices are turned on. Experimental analysis of LED output is one, simulation of LED driver circuit, amplifier circuit is done using Proteus software. Thus a Prototype is been developed.
