The HRLV-MaxSonar-EZ (MB1013) is a high-resolution ultrasonic distance sensor with 1 mm resolution and a range of up to 5 metres. It features multiple output formats, internal temperature compensation, virtually no dead zone, and a calibrated beam pattern — making it an excellent all-round choice for distance sensing applications.

Operating from 2.5V to 5.5V with just 3.1 mA average current draw, it's well suited for battery-powered and low-voltage projects. The sensor automatically calibrates for voltage, humidity, acoustic noise, and temperature before every reading.

Key Features

• 1 mm Resolution – Calibrated accuracy of 0.1% at 1 metre
• 30 mm–5000 mm Range – Virtually no dead zone; objects closer than 30 cm report as 30 cm
• Multiple Outputs – Analog voltage, RS232 or TTL serial, and pulse width
• Internal Temperature Compensation – Built-in sensor adjusts for speed-of-sound changes
• External Temperature Support – Optional HR-MaxTemp sensor for real-time compensation without self-heating drift
• Low Power – 2.5V–5.5V operation, 3.1 mA average current
• Calibrated Beam Pattern – Controlled beam rejects clutter and false triggers from side lobes
• Auto-Calibration – Compensates for voltage, humidity, ambient noise, and temperature
• 10 Hz Reading Rate – Suitable for real-time distance monitoring
