High Resolution, Precision, Low Voltage Ultrasonic Range Finder

MB1003, MB1013, MB1023, MB1033, MB1043

The HRLV-MaxSonar-EZ sensor line is the most cost-effective solution for

applications where precision range-finding, low-voltage operation, and low-cost are

needed. This sensor component module allows users of other more costly precision

rangefinders to lower the cost of their systems without sacrificing performance.

The HRLV-MaxSonar-EZ sensor line provides high accuracy and high resolution ultrasonic proximity detection and

ranging in air, in a package less than one cubic inch. This sensor line features 1-mm resolution, target-size and

operating-voltage compensation for improved accuracy, superior rejection of outside noise sources, internal speed-

of-sound temperature compensation and optional external speed-of-sound temperature compensation. This

ultrasonic sensor detects objects from 1-mm to 5-meters, senses range to objects from 30-cm to 5-meters, with large

objects closer than 30-cm are typically reported as 30-cm

. The interface output formats are pulse width, analog

voltage, and serial digital in either RS232 or TTL. Factory calibration is standard.

Close Range Operation

Applications requiring 100% reading-to-reading reliability should not use MaxSonar sensors at a distance closer than

30cm. Although most users find MaxSonar sensors to work reliably from 0 to 30cm for detecting objects in many

applications, MaxBotix

Inc. does not guarantee operational reliability for objects closer than the minimum reported

distance. Because of ultrasonic physics, these sensors are unable to achieve 100% reliability at close distances.

PAGE 3
HRLV-MaxSonar® - EZ™ Series Auto Calibration Each time the HRLV-MaxSonar-EZ takes a range reading, it calibrates itself. The sensor then uses this data to range objects. If the temperature, humidity, or applied voltage changes during sensor operation; the sensor will continue to function normally over the rated temperature range while applying compensation for changes caused by temperature and voltage.
PAGE 4
HRLV-MaxSonar® - EZ™ Series Supply Voltage Droop and Charge Compensation During power up, the HRLV-MaxSonar-EZ sensor line will calibrate itself for changes in supply voltage. Additionally, the sensor will compensate if the supplied voltage gradually changes. If the voltage applied to the sensor changes faster than 0.5V per second, it is best to remove and reapply power to the sensor. The sensor requires noise free power for best operation.

Operating Modes HRLV-MaxSonar® - EZ™ Series Multiple Sensor Operation Multiple HRLV-MaxSonar-EZ sensors can be used simultaneously in the same environment generally with little to no interference (cross-talk). Even so, some cross-talk may still occur for users wishing to use a large number of sensors in the same environment. This interference is rare and can be up to +/- 1 cm of the target’s distance. Because of this, sensor to sensor interference must be accounted for.
PAGE 7
HRLV-MaxSonar® - EZ™ Series Operating Modes Cont. Independent Sensor Operation The HRLV-MaxSonar-EZ sensors have the capability to operate independently when the user desires. When using the HRLV-MaxSonar-EZ sensors in single or independent sensor operation, it is easiest to allow the sensor to free-run. Free-run is the default mode of operation for all of the MaxBotix Inc., sensors.
PAGE 8
Operations and Timing Continued HRLV-MaxSonar® - EZ™ Series Real-Time Operation - Triggered Real-time or triggered operation allows users to take advantage of a few functions unavailable during free run mode. By operating in triggered mode, a maximum refresh rate of 10Hz can be achieved. This can be valuable for instance, as triggered operation allows users to range targets moving away from or closer to the sensor faster than 240mm/s.
PAGE 9
Operations and Timing Continued HRLV-MaxSonar® - EZ™ Series Sensor Operation - Free-Run When operating in free run mode, the HRLV-MaxSonar-EZ sensors are designed to be used in a variety of indoor environments. Many acoustic noise sources will have little to no effect on the reported range of the HRLV-MaxSonar-EZ sensors. Most range readings are accurately reported. If the range readings are affected, the effect is typically less than 5-mm.

Selecting a HRLV-MaxSonar-EZ HRLV-MaxSonar® - EZ™ Series Different applications require different sensors. The HRLV-MaxSonar-EZ product line offers varied sensitivity to allow you to select the best sensor to meet your needs. The diagram above shows how each product balances sensitivity and noise tolerance. This does not affect the maximum range, pin outputs, or other operations of the sensor. To view how each sensor will function to different sized targets reference the HRLV-MaxSonar-EZ-Beam Patterns.
PAGE 11
HRLV-MaxSonar® - EZ™ Series MB1003 HRLV-MaxSonar-EZ0 Beam Pattern and Uses The HRLV-MaxSonar-EZ0 is the highest sensitivity and widest beam sensor of the HRLV-MaxSonar-EZ sensor series. The wide beam makes this sensor ideal for a variety of applications including people detection, autonomous navigation, and wide beam applications. MB1003 Features and Benefits MB1003 Applications and Uses • Factory calibrated wide beam width • Low operating voltages from 2.5V to 5.
PAGE 12
HRLV-MaxSonar® - EZ™ Series MB1013 HRLV-MaxSonar-EZ1 Beam Pattern and Uses The HRLV-MaxSonar-EZ1 is an indoor ultrasonic sensor and is a quality, low-cost starting place for a customer not sure of which HRLV-MaxSonar-EZ sensor to use. It balances the detection of people and other objects with a narrow beam width.
PAGE 13
HRLV-MaxSonar® - EZ™ Series MB1023 HRLV-MaxSonar-EZ2 Beam Pattern and Uses The HRLV-MaxSonar-EZ2 is a good compromise between sensitivity and side object rejection. The HRLV-MaxSonar-EZ2 is an excellent choice for applications that requires slightly less side object detection and sensitivity than the MB1013 HRLV-MaxSonar-EZ1.
PAGE 14
HRLV-MaxSonar® - EZ™ Series MB1033 HRLV-MaxSonar-EZ3 Beam Pattern and Uses The HRLV-MaxSonar-EZ3 is a narrow beam sensor with good side object rejection. The HRLV-MaxSonar-EZ3 has slightly wider beam width than the MB1043 HRLV-MaxSonar-EZ4 which makes it a good choice for when the HRLV-MaxSonar-EZ4 does not have enough sensitivity for the application.
PAGE 15
HRLV-MaxSonar® - EZ™ Series MB1043 HRLV-MaxSonar-EZ4 Beam Pattern and Uses The HRLV-MaxSonar-EZ4 is the narrowest beam width sensor which is also the least sensitive to side objects offered in the HRLV-MaxSonar-EZ sensor line. The HRLV-MaxSonar-EZ4 is an excellent choice when only larger objects need to be detected.
