{"product_id":"urm13-ultrasonic-sensor","title":"URM13 Ultrasonic Sensor","description":"\u003cp\u003eDFRobot URM13 is an ultrasonic ranging sensor with open single-probe. It supports TRIG Pulse-triggered ranging (SR04 compatible), UART, and I2C communication protocols.\u003c\/p\u003e\n\u003cp\u003eWith a small and compact body, the sensor works well with 3.3V or 5V mainboards like Arduino and Raspberry Pi and it's easy to use and integrate into various applications. The UART mode employs standard Modbus-RTU protocol and integrates receive\/send control output to allow users to easily expand the RS485 interface by using an external RS485 transceiver.\u003c\/p\u003e\n\u003cp\u003eThe URM13 is positioned to be a professional and advanced ultrasonic sensor. The integration of a new precision circuit design and smart detection algorithms on the sensor makes it much smaller and lighter, while still maintaining excellent sensitivity. At the same time, the URM13 sensor is able to automatically detect ambient and electrical noise, and complete the dynamic adjustment and calibration of sensor parameters in real-time, which ensures its stable performance in various complex application scenarios.\u003c\/p\u003e\n\u003ch2\u003eFEATURES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSmall and compact body\u003c\/li\u003e\n\u003cli\u003eExcellent sensitivity\u003c\/li\u003e\n\u003cli\u003eAutomatic noise detection and real-time calibration\u003c\/li\u003e\n\u003cli\u003eHC-SR04 compatible\u003c\/li\u003e\n\u003cli\u003eUART and I2C interface, support to expand RS485\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSPECIFICATION\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply\u003c\/td\u003e\n\u003ctd\u003e3.3~5.5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Instantaneous Work Current\u003c\/td\u003e\n\u003ctd\u003e350mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-10℃～＋70℃\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEffective Measuring Range\u003c\/td\u003e\n\u003ctd\u003e15cm～900cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e1cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e1%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring Frequency\u003c\/td\u003e\n\u003ctd\u003e10Hz Max\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimension\u003c\/td\u003e\n\u003ctd\u003e22 x 20mm \/ 0.87 x 0.79”\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eDOCUMENTS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/wiki.dfrobot.com\/URM13_Ultrasonic_Sensor_SKU_SEN0352\" target=\"_blank\"\u003eProduct wiki\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSHIPPING LIST\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eURM13 Ultrasonic Sensor x1\u003c\/li\u003e\n\u003cli\u003e2.54 Black Single-Row 4PIN Connector x1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":39285256716371,"sku":"SEN0352","price":23.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/SEN0352.jpg?v=1616427724","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/urm13-ultrasonic-sensor","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
