Operating on 3.0–5.5 V, it is directly compatible with 3.3 V and 5 V microcontrollers including Arduino and Raspberry Pi. With an average operating current of just 5 mA and standby current under 14 µA, it is well suited for battery-powered and remote sensing applications.\n\nA built-in temperature sensor provides automatic temperature compensation for improved distance accuracy. The integrated ultrasonic probe offers an approximately 60° detection angle in a compact 27 × 27 mm package, communicating via UART over a 2.54 mm 4-pin interface.\n\nKey Features\n\n\nUltra-Low Power – Average 5 mA operating, <14 µA standby\n\nWide Range – 20–750 cm effective detection distance\n\nBuilt-In Temperature Compensation – On-board sensor corrects for ambient temperature\n\nWide Voltage Range – 3.0–5.5 V DC, compatible with 3.3 V and 5 V systems\n\nUART Interface – 2.54 mm 4-pin connector\n\nProtection – Reverse polarity and overvoltage protection\n\nCompact – Integrated probe design, 27 × 27 mm\n\n\nSpecifications\n\n\nOperating Voltage – 3.0–5.5 V DC\n\nEffective Range – 20–750 cm\n\nDetection Angle – ~60°\n\nDistance Resolution – 1 cm\n\nDistance Error – 1%\n\nAverage Current – <5 mA (continuous measurement)\n\nPeak Current – <9 mA\n\nStandby Current – <14 µA\n\nAcoustic Frequency – 38–42 kHz\n\nBoot Time – <20 ms\n\nMeasurement Period – <60 ms\n\nTemperature Error – ±1 °C\n\nOperating Temperature – −10 °C to +70 °C\n\nOperating Humidity – <75% RH\n\nI/O Mode – Open drain with integrated pull-up resistor\n\nDimensions – 27 × 27 mm\n\nWeight – ~4.2 g\n\n\nIdeal For\n\nBattery-powered distance sensing\nRobotics obstacle avoidance\nLevel measurement and proximity detection\nIoT and remote monitoring projects\n\n\nPackage Contents\n\n1× URM07 UART Ultrasonic Sensor (20–750 cm)\n\n\nResources\n\nWiki Documentation\n","vendor":"DFRobot","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":14136,"title":"Default Title","sku":"DF-SEN0153","price":25.61,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
