LiFi Nano V2

OVERVIEW:

A very innovative technology know as 'LiFi' or 'Light Fidelity' is taking a leap. Data transfer from one source to another happens over 'Light'. Technically, if the LED is ON, one can transmit a digital string of 1, if it’s OFF then user can transmit a string of 0. 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. Presenting you with Research Design Labs' LiFi Nano Module. 

 FEATURES:

• It can transmit data 38400 baud rate serially.
• Distance can be acheived 1 to 1.5 meter for wireless open optical communication.
• High intensity LED.
