{"title":"A02YYUW Waterproof Ultrasonic Sensor","handle":"a02yyuw-waterproof-ultrasonic-sensor","url":"/products/a02yyuw-waterproof-ultrasonic-sensor","description":"A commercial-grade waterproof ultrasonic distance sensor with UART serial output. The A02YYUW features a much smaller blind zone (3 cm) and wider sensing angle than many comparable sensors, plus penetration through smog and dust for reliable outdoor use.\n\nThe closed separated-probe design is waterproof (IP67) and dustproof, making it well suited to harsh and moist environments. All signal processing is integrated inside the module — connect via UART at 9600 bps and read distance values directly.\n\nSpecifications\n\n\nOperating Voltage – 3.3–5 V\n\nAverage Current – &lt;8 mA\n\nBlind Zone – 3 cm\n\nDetection Range (Flat Object) – 3–450 cm\n\nOutput – UART (9600 bps)\n\nResponse Time – 100 ms\n\nSensing Angle – 60°\n\nWaterproof Grade – IP67\n\nOperating Temperature – -15 to 60°C\n\nStorage Temperature – -25 to 80°C\n\n\nAlso Available\n\n\nA01NYUB Waterproof Ultrasonic Sensor – longer range (7.5 m with bell-mouth), 28 cm blind zone\n\n\nIdeal For\n\nReversing / parking distance sensors\nObstacle-avoidance robots\nClose-range object detection (3 cm minimum)\nOutdoor or wet-environment distance measurement\n\n\nResources\n\nProduct Wiki\n\n\nPackage Contents\n\n1× A02YYUW Waterproof Ultrasonic Sensor\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4772,"title":"Default Title","sku":"DF-SEN0311","price":31.81,"on_sale":false,"in_stock":true,"available_quantity":1538,"option1":"Default Title"}]}
