INFRARED WIRELESS UNDERWATER COMMUNICATION SYSTEM

Abstract

The Wireless communication has been booming in the recent years. However, not much has been done to accomplish communication in water in a wireless manner which can be useful in many scenarios. Most of the communication modes that are existing as of now are either not reliable or are very expensive. IR rays can pass through water and thus be used in case of line of sight for communication purpose in this medium. This IR communication using Keyboard uses two units both controlled by ATmega family microcontroller. Both of the units have IR trans-receivers as communicating agents. Keyboards are needed to be connected on both the ends to enter input to the system. The communication messages get displayed on the LCD connected to the system. The system communicates with confirmation key that is sent back by receiving unit to the sending unit. In this way wireless communication is implemented with great efficiency within a line of sight range of about 3-4 meters under the water with the help of IR wireless underwater Communication project.
