Li-Fi KIT

lifi technology kit is available in market, kit is around rs-2000 to 6000 variant.

           A high-brightness light-emitting diodes. if the LED is ON, user can transmit a digital content.  It can be switched ON and OFF very quickly, which gives instant opportunity for transmitting data. It is possible to encode data in the light by varying the rate at which the LEDs flicker ON and OFF to pass different strings of 1s and 0s. The modulation is so fast that the human eye doesn’t notice. There are over 14 billion light bulbs used across the world, which needs to be replaced with LEDs ones that transmit data.

Features:

• It can transmit data 38400 baud rate serialy.
• Distance can be acheived 1 Feet to 10 Feet for wireless open optical communication*.
• High intensity LED matrix.
• High quality PCB FR4 Grade with FPT Certified.

Applications:

• Indoor wireless open optical communication.
• Indoor navigation.
• Under water visible light communication.
• Smart indoor blind assistive application.
• Vehicle to vehicle communication.

I/O connections:

Single panel will give you the the distance maximum up to 1Ft-30CM. By cascading 4 LED panel you can communicate  with distance of 120CM.
