Underwater Wireless Communication Using Visible Light

Megha M. Wankhade, Sayali S. Suryawanshi, Mrunal N. Lonare, Yash D. Rajurkar


The proposed method leads to a data communication architecture that transmits audio through water using visible light. This model uses a PIC microcontroller as hardware. The transmitter is a laser, while the receiver is a photodiode receiver. Today, high-speed wireless communications are required for many commercial, research and subsea applications. Current underwater communication methods, such as acoustic communication, suffer from significant delay and poor data quality, while underwater radio communication suffers from attenuated signals. Newly developed optical wireless communication technology can achieve data transmission with less than the desired attenuation in visible light, resulting in better data transmission. The technology concept focuses on data transfer
via visible light communication during underwater wireless transmission. Thoughts created a communication system that transmitted audio through water. In this way, information is transmitted from the transmitter to the receiver under water via line of sight, and the on and off flashes of the laser (1 and 0 bits) are monitored. The use of this technique can be used to transmit the message across quickly. More lasers and photodiodes can be used in the future if necessary to transmit good images and sound. It will not only increase efficiency and data transfer, but also increase data transfer security. Both the probability and speed of transmission will rise as a result.
