HRLV-MaxSonar-EZ MB1013 Ultrasonic Distance Sensor

HRLV‑MaxSonar‑EZ high‑resolution ultrasonic sensor delivers precise non‑contact distance measurement for robotics, automation, and embedded control systems. This ultrasonic ranging module combines millimeter‑level resolution, stable long‑range detection, and exceptionally low power consumption within a compact component‑level package. Designed for seamless integration with popular controllers such as Arduino, this precision distance sensing board provides multiple output formats including analog voltage, pulse width, and serial data. Reliable beam control, automatic environmental calibration, and flexible voltage operation make this ultrasonic measurement module suitable for professional engineering projects, smart robotics platforms, and experimental prototyping environments.

Millimeter‑Level Precision Distance Measurement

Advanced ultrasonic ranging technology enables 1 mm (0.04") resolution with calibrated accuracy reaching approximately 0.1% at a distance of 1 meter. This high‑precision acoustic measurement module operates at 42 kHz and provides stable distance readings across a wide detection range up to 5000 mm. Minimal sensor dead zone allows reliable measurement even at short distances, improving performance for robotic navigation, obstacle detection systems, and automated positioning tasks requiring fine measurement granularity.

Intelligent Temperature Compensation Options

An integrated temperature sensor enables automatic compensation for speed‑of‑sound variations caused by air temperature changes. Immediate accuracy after power‑up makes this ultrasonic distance sensor particularly effective for battery‑powered systems where power cycling occurs frequently. For environments requiring higher thermal accuracy, compatibility with the external HR‑MaxTemp temperature sensor enables real‑time ambient monitoring while eliminating drift caused by internal self‑heating, ensuring consistent range readings across changing environmental conditions.

Multiple Output Interfaces for Flexible Integration

This ultrasonic detection module provides three simultaneous output formats: analog voltage, pulse width, and asynchronous serial communication. Serial output supports both RS232 and TTL modes through a selectable jumper configuration. Such versatile interface design allows straightforward integration with microcontrollers, embedded processors, and industrial controllers without complex configuration commands. Direct hardware‑level compatibility simplifies development for robotics platforms, automation controllers, and sensor‑driven embedded applications.

Controlled Beam Pattern with Automatic Calibration

A carefully engineered acoustic beam profile reduces side‑lobe interference and minimizes false detections from objects outside the primary sensing area. Firmware filtering further improves noise tolerance and clutter rejection for stable operation in complex environments. Each ultrasonic ranging board undergoes factory beam calibration and performs automatic environmental adjustment before every reading, compensating for voltage variation, humidity, acoustic interference, and electrical noise to maintain consistent measurement reliability.

Such capabilities make this long‑range ultrasonic distance sensor suitable for mobile robotics, smart obstacle detection systems, automated level measurement, and embedded sensing applications requiring reliable non‑contact ranging performance.
