DFRobot Underwater Ultrasonic Obstacle Avoidance Sensor (6m, IP68)

This is an underwater ultrasonic obstacle avoidance sensor specifically designed for underwater applications. It operates on a wide voltage range of 5-24V and features compact size, minimal blind spots, high precision, and high protection. Its underwater measurement range is from 5-600cm.

With an IP68 protection rating, this sensor can replace a camera for obstacle avoidance and meet the requirements of normal underwater navigation speeds. By using this obstacle avoidance sensor, underwater vehicles can achieve true “unmanned driving” without the need for human observation. Even at a depth of 10m, obstacle avoidance can still be easily accomplished.

Thanks to its small size and minimal blind spots, this sensor takes up minimal space and can be easily integrated into various projects.
