It measures distance by sending out a sound wave at a specific frequency and listening for that sound wave to bounce back.\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eSince it is known that sound travels through air at about 344 m\/s (1129 ft\/s), you can take the time for the sound wave to return and multiply it by 344 meters (or 1129 feet) to find the total round-trip distance of the sound wave. Round-trip means that the sound wave traveled 2 times the distance to the object before it was detected by the sensor; it includes the 'trip' from the sonar sensor to the object AND the 'trip' from the object to the Ultrasonic sensor (after the sound wave bounced off the object). To find the distance to the object, simply divide the round-trip distance in half.\u003c\/p\u003e\n\u003cp\u003eDFRobot URM09 is an\u003cspan\u003e ultrasonic sensor\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003especially designed for fast ranging and obstacle avoidance applications. Its measuring frequency can reach up to 30Hz. The sensor adopts built-in temperature compensation and analog output. Meanwhile, it can provide accurate distance measurement within 500cm. The sensor is compatible with Arduino, Raspberry Pi or other main-control boards with 3.3V or 5V logic level.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv\u003e\u003cimg alt=\"URM09 Beam Angle\" title=\"URM09 Beam Angle\" src=\"https:\/\/image.dfrobot.com\/image\/data\/SEN0304\/URM09-2.png\" original=\"https:\/\/image.dfrobot.com\/image\/data\/SEN0304\/URM09-2.png\"\u003e\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eURM09 Beam Angle\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eIf you need want to learn more about ultrasonic sensors, please\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/www.dfrobot.com\/blog-1491.html\" target=\"_blank\"\u003eclick here\u003c\/a\u003e\u003cspan\u003e \u003c\/span\u003eto check DFRobot Ultrasonic Sensor Selection Guide.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch4\u003eSPECIFICATION\u003c\/h4\u003e\n\u003cdiv class=\"desCon\"\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003ePower Supply: 3.3~5.5V DC\u003c\/li\u003e\n\u003cli\u003eOperating Current: 20mA\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -10℃～＋70℃\u003c\/li\u003e\n\u003cli\u003eMeasurement Range: 2cm～500cm\u003c\/li\u003e\n\u003cli\u003eResolution: 1cm\u003c\/li\u003e\n\u003cli\u003eAccuracy: 1%\u003c\/li\u003e\n\u003cli\u003eFrequency: 30Hz Max\u003c\/li\u003e\n\u003cli\u003eDimension: 47mm × 22 mm\/1.85× 0.87”\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\n\u003c\/div\u003e\n\u003ch4\u003ePROJECTS\u003c\/h4\u003e\n\u003cdiv class=\"desCon\"\u003e\n\u003cb\u003eProject 1.\u003c\/b\u003e\u003ca href=\"https:\/\/www.youtube.com\/watch?v=SV7SMtE6MAY\" target=\"_blank\"\u003eTerminator HK ~ Arduino \u0026amp; Raspberry Pi Robotics Project | 314Reactor\u003c\/a\u003e\u003cbr\u003eI decided to chuck some extra hardware at it alongside some cool machine learning stuff and really make a cool representation of the HK in Arduino\/Raspberry Pi form.\u003cbr\u003eMain Components:\u003cbr\u003e\u003ca href=\"https:\/\/www.dfrobot.com\/product-1860.html\" target=\"_blank\"\u003eBlack Gladiator - Tracked Robot Chassis\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/www.dfrobot.com\/product-1667.html\" target=\"_blank\"\u003eGravity: IO Expansion \u0026amp; Motor Driver Shield\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/www.dfrobot.com\/product-1862.html\" target=\"_blank\"\u003eGravity: URM09 Analog Ultrasonic Sensor\u003c\/a\u003e\u003cbr\u003e\n\u003cp\u003e\u003cb\u003eProject 2.\u003cspan\u003e \u003c\/span\u003e\u003c\/b\u003e\u003ca href=\"https:\/\/community.dfrobot.com\/makelog-308422.html\" target=\"_blank\"\u003eMini Apple II-“Surprise” Machine for Halloween\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/gCdgLaUaEPc\" width=\"640\" height=\"360\" class=\"note-video-clip\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cb\u003eProject 3.\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/community.dfrobot.com\/makelog-312463.html\" target=\"_blank\"\u003ePing Pong Balls Collector - HuskyLens AI Robotic Ball Picker\u003c\/a\u003e\u003c\/b\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cb\u003eIntroduction:\u003c\/b\u003e\n\u003cp\u003eI made a radio-controlled \"robotic ball picker\" last time and it performed well.
