## Description

An underwater ultrasonic obstacle avoidance sensor designed specifically for submerged applications. With an IP68 protection rating and a measurement range of 5–600 cm, it enables underwater vehicles to detect and avoid obstacles without relying on cameras or human observation. Operating on a wide 5–24V voltage range, this compact sensor features minimal blind spots, fast response times, and high precision. It works reliably at depths up to 10 m, making it ideal for autonomous underwater navigation. Note: This sensor can only be used underwater — it requires the presence of water to provide accurate readings. Key Features IP68 Waterproof Rating – Fully submersible, operates at depths up to 10 m 5–600 cm Range – Wide detection range for effective obstacle avoidance UART Output – Simple serial communication for easy integration Wide Voltage Input (5–24V) – Compatible with a variety of power sources Compact Design – Minimal blind zone, takes up very little space Fast Response – 14 ms output response time with ≤500 ms startup Specifications Measurement Range – 5–600 cm Accuracy – ±(0.5 + S×0.5%) cm below 2 m; ±(1 + S×1%) cm above 2 m Operating Voltage – 5–24V Standby Current – ≤1 mA Operating Current – ≤10 mA Output Mode – UART controlled Beam Angle – 8–16° Startup Time – ≤500 ms Response Time – 14 ms Operating Temperature – -15 to 50°C Storage Temperature – -25 to 80°C Storage Humidity – 65–90% RH (non-condensing) Ideal For Underwater robot obstacle avoidance and autonomous navigation ROV and AUV depth and proximity sensing Underwater exploration and survey projects Water depth measurement applications Package Contents 1× IP68 Underwater Ultrasonic Obstacle Avoidance Sensor (6 m) Resources DFRobot Product Wiki
