Abstract: Light Fidelity (Li-Fi) is an emerging technology that is expected to be one of the fastest wireless accesses in future and is used for establishing wireless communication at a very high speed. In this paper, basic LED is used for the purpose of data transfer. The main objective is to use the LED for illumination as well as for the transmission of data automatically in a room by sensing the presence of humans using piezoelectric sensor. Here, the data to be transmitted is audio signal. Since it is used for both the purposes, energy is conserved which is important in the current century. A Piezoelectric sensor is used to detect the person when they enter into a room. So it can be used in waiting halls to make the person entertained by playing an audio when they enter the hall.
