Scuba diving is one of the most famous adventure sports amongst various generations of people. While diving inside a deep-sea diver must use breathing equipment which is completely different from surface air supply which is known as SCUBA. SCUBA is an acronym for Self-Contained Underwater Breathing Apparatus. SCUBA diving is often performed in the presence and under the guidance of professionally trained divers. It becomes very essential to have proper communication between the diver and the trainer as the smallest delay or miscommunication may even cause death. In this project, we have implemented a reliable underwater communication system with the help of Arduino, flex sensors and IR sensors The objective of the scuba communication system is to make underwater communication simpler and more practicable at greater distances than are visible underwater. Divers frequently face the dilemma of learning signals and wasting time in dives to communicate. Signs for scuba diving are monotonous and frequently fail to convey the intended information. In addition, scuba signs as they currently exist are imperfect and lack vital information that could often mean life or death. The scuba communication device facilitates underwater communication by incorporating an role into diving gloves, which displays the message a fellow diver may be attempting to convey. The system uses 5 flex sensors and a 6-axis IMU to determine precisely what sign the user is displaying. Since the system is meant for scuba diving the glove has also been water-proofed to prevent water from destroying the electronics. Each finger as well as the direction is necessary for understanding the signs; therefore, a calibration code has been incorporated to ensure accurate data. Additionally, it does not require any additional equipment and is merely an attachment to existing dive gloves. After consulting with numerous seasoned divers, we determined that the usage of sound would be distracting during the dive and that headphones would obstruct the sinuses in the ear, which might be exceedingly hazardous. Using an IR sensor and receiver, an Arduino Nano is utilized for processing and transmitting data. The system is a significant improvement over the decades-old methods of underwater communication.
