Hybrid Communication Architecture for Subaquatic Data Transmission

Underwater communication and monitoring have become more important for marine research, aquaculture, water quality monitoring, and environmental observation. Conventional underwater communication techniques frequently encounter issues including restricted transmission range, elevated costs, signal degradation, and challenges in real-time monitoring. An Internet of Things (IoT) based underwater communication system is suggested to get around these problems. The ESP8266 NodeMCU is the main processing unit in the proposed system. It collects and sends data about the environment under the water. A LoRa SX1278 module is used to send data wirelessly over long distances between the monitoring station and the underwater sensor nodes. A DS18B20 measures the temperature of the water, and a turbidity sensor keeps an eye on the water's clarity or quality. An OLED display shows the data that was collected, and it can also be sent to a remote monitoring system for more analysis. The system is made to work with cable connections in water to make sure that sensors can talk to each other reliably. LoRa technology, on the other hand, lets sensors send data wirelessly over long distances with little power use. IoT technology makes real-time monitoring, data access, and system efficiency better. The proposed system has a lot of benefits, such as real-time monitoring, less need for people to be involved, lower costs, and less energy use. It can be used in a number of areas, including marine research, aquaculture, environmental protection, and monitoring water quality.Overall, this project shows that IoT technology can be used to communicate underwater in a quick and reliable way. It also shows how traditional monitoring systems can be improved and how smart environmental monitoring can be improved.
