The Underwater media is the most challenging for data communication. It is because of its traits. Electromagnetic waves, acoustic waves, and optical signals are the different types of communication currently used in water. But each of these has its own shortcomings. In this article, a Li-Fi technology is used for data transmission in a water medium to get over these issues. The German physicist Harald Hass first introduced the term Li-Fi, which stands for “light fidelity”, in 2011. Li-Fi technology transmits data using visible light. This technology’s fundamental premise is that data may be transferred via LED light, which intensity varies even more quickly than the human eye. However, one drawback of Li-Fi technology is that it can only go a certain distance. In this project, we utilise a booster to strengthen the light so that it may travel further. The Arduino board can be used as a microcontroller to manage data processing operations and regulate the transmission and reception of light signals. It is referred to as the Wi-Fi version that has been optimised in recent times. Data can be communicated in this project in the form of text, audio, or even video.
