Fisherman Auto Safety Boating And Boundary Information System

Illegal maritime border crossings and delayed distress communication pose serious risks to fishermen operating near international sea boundaries. To address this issue, this project proposes a GPS-based Maritime Border Alert and Safety System designed to continuously monitor a vessel's real-time location and ensure safety through automated alerts and control actions. The system uses a GPS module to obtain live latitude and longitude coordinates of the vessel. Predefined Indian maritime boundary coordinates are stored internally and compared continuously with real-time GPS data to determine proximity to national borders. Based on this distance, a multi-level alert mechanism is implemented: a low-level alert at 15 km, a medium-level alert at 10 km, and a high-level alert at 5 km. If the vessel crosses the maritime boundary, the system automatically disconnects the motor using a relay module to prevent further movement. Simultaneously, a GSM module (SIM800L) sends an SMS alert containing a Google Maps link to predefined contacts such as Coastal Guard authorities and family members. Furthermore, an SOS button allows fishermen to manually trigger emergency alerts. This integrated system ensures improved safety, security, and rapid response in maritime environments.
