It features the narrowest beam width in the HRLV-MaxSonar-EZ sensor line, making it ideal for detecting larger objects while ignoring smaller ones.\n\nThe sensor provides virtually noise-free readings through high-output acoustic power, continuously variable gain, real-time automatic calibration, waveform signature analysis, and noise rejection algorithms. Multiple output formats are available: analogue voltage, serial (RS232 or TTL), and pulse width.\n\nKey Features\n\n\n1 mm Resolution – High-precision millimetre-level distance measurement\n\n300–5000 mm Range – Objects closer than 300 mm typically read as 300 mm\n\nNarrowest Beam – Most focused beam in the HRLV-MaxSonar-EZ line, best for large object detection\n\nMultiple Outputs – Analogue voltage, RS232 or TTL serial, and pulse width\n\nReal-Time Auto Calibration – Compensates for voltage, humidity, and ambient noise\n\nFirmware Noise Filtering – Enhanced clutter rejection and noise tolerance\n\nInternal Temperature Compensation – With optional external sensor (HRMaxTemp)\n\nCompact Module – Less than one cubic inch with mounting holes\n\n\nSpecifications\n\n\nSensor Frequency – 42 kHz ultrasonic\n\nRange – 300–5000 mm\n\nResolution – 1 mm\n\nRead Rate – 10 Hz\n\nSupply Voltage – 2.5–5.5V\n\nCurrent Draw – 3.1 mA average\n\nOperating Temperature – 0°C to +65°C\n\nCompliance – RoHS\n\n\nIdeal For\n\nLarge object detection and proximity sensing\nPrecision distance measurement\nRobotics and autonomous navigation\nLevel sensing and fill monitoring\n\n\nResources\n\nHRLV-MaxSonar-EZ4 Datasheet (PDF)\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4985,"title":"Default Title","sku":"DF-SEN0269","price":85.24,"on_sale":false,"in_stock":true,"available_quantity":1,"option1":"Default Title"}]}
