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

Jargon buster
Plain-language definitions for the technical terms used above.
- Temperature compensation
- Temperature compensation is when a sensor or instrument adjusts its readings to reduce errors caused by changes in temperature. This matters because a sensor's raw output often drifts as conditions warm or cool, so compensation keeps readings more consistent and accurate over time.
- TTL serial
- A simple serial data connection that uses microcontroller logic-level voltages (typically 3.3 V or 5 V) rather than the higher, inverted voltages of computer RS-232. When a device lists TTL serial, it can usually wire straight to a microcontroller's UART pins or to a USB-to-TTL serial adapter, but it needs a level converter before connecting to a true RS-232 port.
