{"title":"A01NYUB Waterproof Ultrasonic Sensor","handle":"a01nyub-waterproof-ultrasonic-sensor","url":"/products/a01nyub-waterproof-ultrasonic-sensor","description":"A waterproof ultrasonic distance sensor with UART serial output. The A01NYUB measures distance by timing the ultrasonic pulse echo and outputs the result directly via asynchronous serial at 9600 bps — no external signal processing needed. With the included removable bell-mouth fitted, the effective range extends to 7.5 m.\n\nThe closed probe design is waterproof (IP67) and dustproof, with penetration through smog and dust. Connects easily to Arduino, Raspberry Pi, or any MCU with a serial interface.\n\nSpecifications\n\n\nOperating Voltage – 3.3–5 V\n\nAverage Current – <15 mA\n\nBlind Zone – 28 cm\n\nDetection Range (Flat Object) – 28–750 cm\n\nOutput – UART (9600 bps)\n\nResponse Time – 100 ms\n\nProbe Centre Frequency – 40 kHz ± 1.0 kHz\n\nSensing Angle – 55° with bell-mouth, 40° without\n\nWaterproof Grade – IP67\n\nOperating Temperature – -15 to 60°C\n\nStorage Temperature – -25 to 80°C\n\n\nIdeal For\n\nReversing / parking distance sensors\nObstacle-avoidance robots\nObject proximity detection\nOutdoor or wet-environment distance measurement\n\n\nResources\n\nProduct Wiki\n\n\nPackage Contents\n\n1× A01NYUB Waterproof Ultrasonic Sensor\n1× Removable Bell-Mouth\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4765,"title":"Default Title","sku":"DF-SEN0313","price":53.44,"on_sale":false,"in_stock":true,"available_quantity":2,"option1":"Default Title"}]}
