This is an underwater ultrasonic obstacle avoidance sensor with a 5-24V wide voltage range, compact size, minimal blind spots, high precision, and high protection, plus a 2-300cm underwater measurement range. IP68-rated, it replaces cameras for obstacle avoidance (meeting normal underwater navigation speeds), allowing underwater vehicles to achieve true "unmanned driving" without human observation—even at 10m depth. Its small size and minimal blind spots make it easy to integrate into various projects.
