{"title":"IP68 Underwater Ultrasonic Obstacle Avoidance Sensor (3m, UART)","handle":"ip68-underwater-ultrasonic-obstacle-avoidance-sensor-3m-uart","url":"/products/ip68-underwater-ultrasonic-obstacle-avoidance-sensor-3m-uart","description":"An IP68-rated ultrasonic obstacle avoidance sensor specifically designed for underwater applications. With a measurement range of 2–300cm and UART output, this compact sensor enables underwater vehicles and robots to detect obstacles without relying on cameras.\n\nOperating on a wide 5–24V voltage range with ultra-low power consumption, the sensor features a narrow 5–10° beam angle and minimal blind spots. It can operate at depths up to 10 metres, making it suitable for autonomous underwater navigation and depth measurement.\n\nKey Features\n\n\nIP68 Waterproof – Fully submersible, rated for underwater use at depths up to 10m\n\n2–300cm Range – Ultrasonic obstacle detection with minimal blind zone\n\nUART Output – Easy integration with microcontrollers via serial communication\n\nWide Voltage Range – 5–24V operating voltage\n\nUltra-Low Power – ≤1mA standby, ≤10mA operating current\n\nFast Response – 10ms output response time, ≤500ms power-on startup\n\nCompact Design – Small form factor for easy integration into underwater projects\n\n\nSpecifications\n\n\nMeasurement Range: 2–300cm\n\nAccuracy: ±(0.5 + S×0.5%) cm below 2m; ±(1 + S×1%) cm above 2m\n\nOperating Voltage: 5–24V\n\nStandby Current: ≤1mA\n\nOperating Current: ≤10mA\n\nOutput: UART\n\nBeam Angle: 5–10°\n\nResponse Time: 10ms\n\nPower-On Time: ≤500ms\n\nOperating Temperature: −15°C to 50°C\n\nStorage Temperature: −25°C to 80°C\n\nStorage Humidity: 65%–90% RH (non-condensing)\n\n\nIdeal For\n\nUnderwater robot obstacle avoidance\nAutonomous underwater vehicle (AUV) navigation\nUnderwater depth and distance measurement\nROV and submersible projects\n\n\n\nWarning: This sensor can only be used underwater.
