Note: The sensor can only be used underwater as it requires the presence of water to provide accurate data.
The IP68 Underwater Ultrasonic Obstacle Avoidance Sensor (3m, UART) is designed specifically for underwater robotics and navigation. Featuring a 2–300cm detection range, this compact and lightweight sensor delivers high precision with minimal blind spots, making it suitable for real-time obstacle detection and depth measurement. With an IP68 protection rating, it operates reliably underwater, even at depths of up to 10m, enabling autonomous vehicles to achieve effective obstacle avoidance without the need for visual cameras. The sensor supports a wide input voltage of 5–24V, consumes minimal power, and communicates via a UART interface for easy integration with microcontrollers. Its fast 10ms response time and narrow detection angle of 5–10° ensure accurate performance in dynamic underwater environments. This sensor is a perfect fit for AUVs, ROVs, underwater drones, and research applications requiring robust and precise underwater navigation. Featured By RoboticsBD.
