Implementation of Li-Fi based home automation system

Abstract

This paper presents an Implementation of Li-Fi based home automation system prototype. This system was develop to verify the effect of LED types on VLC transmission. LED is used to transmit the input data information to the receiver LDR through visible light communication (VLC). Arduino microcontroller was used to retrieve information from the temperature sensor, light sensor, PIR sensor and MQ2 gas sensor. The output data of sensors were sent to LDR by LED. The result demonstrates that the colour types of LED has an effect on transmission distance and the voltage of LED is proportional to the distance. Red LED has better performance compared to others.
