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.\n\nOperating 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.\n\n\nNote: This sensor can only be used underwater — it requires the presence of water to provide accurate readings.\n\n\nKey Features\n\n\nIP68 Waterproof Rating – Fully submersible, operates at depths up to 10 m\n\n5–600 cm Range – Wide detection range for effective obstacle avoidance\n\nUART Output – Simple serial communication for easy integration\n\nWide Voltage Input (5–24V) – Compatible with a variety of power sources\n\nCompact Design – Minimal blind zone, takes up very little space\n\nFast Response – 14 ms output response time with ≤500 ms startup\n\n\nSpecifications\n\n\nMeasurement Range – 5–600 cm\n\nAccuracy – ±(0.5 + S×0.5%) cm below 2 m; ±(1 + S×1%) cm above 2 m\n\nOperating Voltage – 5–24V\n\nStandby Current – ≤1 mA\n\nOperating Current – ≤10 mA\n\nOutput Mode – UART controlled\n\nBeam Angle – 8–16°\n\nStartup Time – ≤500 ms\n\nResponse Time – 14 ms\n\nOperating Temperature – -15 to 50°C\n\nStorage Temperature – -25 to 80°C\n\nStorage Humidity – 65–90% RH (non-condensing)\n\n\nIdeal For\n\nUnderwater robot obstacle avoidance and autonomous navigation\nROV and AUV depth and proximity sensing\nUnderwater exploration and survey projects\nWater depth measurement applications\n\n\nPackage Contents\n\n1× IP68 Underwater Ultrasonic Obstacle Avoidance Sensor (6 m)\n\n\nResources\n\nDFRobot Product Wiki\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":574,"title":"Default Title","sku":"DF-SEN0599","mpn":"SEN0599","price":65.0,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":90,"option1":"Default Title"}]}
