Feature 1 IP68 WATERPROOF: Ultrasonic obstacle avoidance sensor designed for underwater application, with IP68 waterproof grade, convenient and practical. 2 SENSOR ADVANTAGE: The ultrasonic underwater ranging sensor has the advantages of compact size, small blind spot (minimum 2cm), and high accuracy. 3 OBSTACLE AVOIDANCE: This sensor can replace traditional camera, and meet the requirements for underwater obstacle avoidance at normal sailing speeds. 4 MULTIPLE FUNCTIONS: Supports module address, angle, and baud rate modification, with electrostatic protection design, compliant with IEC 6100042 standards. 5 APPLICABLE SCENE: The ultrasonic distance measuring sensor has a range of 6 meters for flat objects, suitable for underwater robots, and swimming pools, etc.Item Type: Underwater Distance SensorTemperature Compensation: YesWaterproof Grade: IP68Working Temperature: -15-55Baud Rate: 115200bpsFunction: Supports module address, angle, baud rate modification, electrostatic protection design, and complies with IEC 61000-4-2 standards.Working Voltage: DC5-24VStandby Current: 1mABlind Spot Distance: Approx. 5cm / 2inFlat Object Range: Approx. 6m / 19.7ftPower On Working Time: 1sWork Cycle: ControlledDistance measurement accuracyWithin 2 Meter: (0.5+Sx0.5%)Beyond 2 Meter: (1+Sx1%)Angle: 8-16 Package List1 x Underwater Distance SensorNote1. Response time measured at 9600 baud rate;2. The module is static in the underwater 30CM, the water temperature is 25, the water surface is calm, no current test data, S represents the current distance;3. The module is static at 30CM underwater, the water temperature is 25, the water surface is calm, and the data is obtained by using PVC pipe at 0.7 meters.
