The Smart Green Ship Sensor-Based Stability and Safety Monitoring System with Integrated Oil Spill Collector is an intelligent, eco-friendly marine solution designed to enhance ship safety, stability, and environmental protection through real-time monitoring and automated control. This system is built around an ESP32 microcontroller that continuously collects and processes data from multiple onboard sensors. An MPU6050 gyroscope monitors ship tilt and orientation across the X, Y, and Z axes to ensure stability during operation. A load cell measures weight variations to detect imbalance or overload conditions, while an ultrasonic sensor (SR04) identifies nearby obstacles to prevent collisions and ensure safe navigation. The ship’s propulsion is controlled using dual DC motors driven by an L298 motor driver, enabling directional movement via a web-based interface. Additionally, an oil spill collection mechanism is integrated using a belt-driven DC motor controlled through a MOSFET switching circuit. This allows remote activation of the oil collection belt to gather surface oil contaminants efficiently. All critical parameters — including ship orientation, obstacle distance, load weight, propulsion movement, and oil belt status — are transmitted in real time to a web dashboard via ESP32 Wi-Fi connectivity. This enables remote monitoring and control of ship navigation and pollution management systems from any location. Powered by a Li-ion battery system, the proposed design promotes sustainable marine operations by combining smart navigation safety with environmental cleanup functionality. The system provides a low-cost, scalable solution for future autonomous marine vessels focused on both operational safety and ecological preservation.
