[0069] When using an Arduino-based environmental monitoring device according to Example 1:

[0070] When the environmental monitoring device is activated, the central controller 4 begins running the navigation program. This program's primary task is to plan the vessel's route. Using a pre-set destination and obstacle avoidance strategy, the central controller 4 calculates the optimal path to ensure the vessel safely reaches its destination.

[0071] The navigation process relies on GPS data provided by the real-time positioning device 8. The real-time positioning device 8 continuously collects satellite signals to obtain the accurate coordinates of the current position. These coordinate data are transmitted to the central controller 4 for use in navigation decisions.

[0072] The device is equipped with ultrasonic sensors, distributed on the front, left, and right sides of the hull, for detecting obstacles. When the sensors detect an obstacle in front, on the left, or on the right, the central controller 4 will initiate an automatic obstacle avoidance program.

[0075] At the same time, the central controller 4 will compare the real-time positioning data with the preset navigation route to ensure that the hull sails stably along the preset route. If any deviation from the route is found, the system will automatically make corrections to put the hull back on the correct navigation path.
