Experimental System for Monitoring Maritime Areas Using Raspberry Pi

This paper presents the design and validation of a smart buoy prototype, built on a compact computing platform and an integrated set of acoustic, atmospheric, and pressure sensors. The system is intended for real-time monitoring of environmental parameters relevant to maritime security, ecosystem protection, and the management of critical offshore infrastructure. Experimental trials demonstrated the device’s capability to record variations in temperature, pressure, and humidity, as well as to detect nearby objects and predefined acoustic signals associated with potentially hazardous scenarios. Comparative analysis against reference values highlighted a concordance of 93.6% for atmospheric measurements and 91.3% for acoustic detections, confirming the system’s reliability under real operating conditions. The results validate the concept of a modular and autonomous buoy, offering practical applications for maritime monitoring and the prevention of critical events.
