Health monitoring and image restoration for a human in under water using acoustic communication

Abstract

Human divers encounter special difficulties when venturing into underwater habitats, such as the requirement for reliable health tracking and communication systems. Our research suggests a new way for underwater divers to be monitored in real-time and their images restored using acoustic communication. To accomplish all of these goals, our system incorporates the following components: a power supply unit, an L293D motor driver, a buzzer, a GPS module, sound absorption sensors, and a NodeMCU (ESP8266). The NodeMCU coordinates the gathering of data from a number of sensors and modules and acts as their central processing unit. In order to keep tabs on the diver's vital signs and stress levels, EDA sensors track their physiological parameters. To avoid the restrictions inherent in conventional RF communication underwater, the data is wirelessly transmitted via acoustic communication.A GPS module has been integrated into the system to help with direction and location tracking, allowing the diver to be precisely located. The submerged acoustic environment can be better assessed with the help of sound absorption sensors, which allow for more efficient communication. If the EDA sensors detect any signs of poor health or distress, a buzzer alert will be activated to warn the diver and any nearby support teams. Also, to improve visibility underwater, picture restoration capabilities are built in. These function by lessening the harm that water turbidity causes by processing captured images using sophisticated algorithms. The power supply unit, which supplies enough energy to all components, ensures the system's dependable operation. For possible future upgrades, like underwater robotic manipulators, the L293D motor driver allows control of external actuators. In sum, the system we're proposing is a huge step forward in the field of submerged health monitoring and communication; it will improve divers' capacity to explore and navigate the seafloor safely and efficiently while also providing them with real-time insights into their health.
