The advancement of a robust and efficient Wireless Sensor Network (WSN) for monitoring the marine environment is crucial for improving marine resource management, monitoring climate change, and ensuring maritime safety. In this study, a WSN is deployed to integrate with Long Range Communication (LoRa) technology for real-time marine environmental monitoring. Marine environments pose significant challenges due to their vastness, harsh conditions, and the need for continuous monitoring of various parameters such as temperature, acceleration, pressure, and water quality. The proposed system cover vast marine areas through LoRa communication ensuring minimal energy consumption. The proposed study use a set of marine sensors distributed across key locations in the marine environment, capable of monitoring a range of physical parameters. Data is collected and transmitted to a central base station for processing and analysis.
