HRUSB-MaxSonar

-EZ™ Series

USB Rangefinder, High Resolution Precision

MB1403, MB1413, MB1423, MB1433, MB1443

The HRUSB-MaxSonar-EZ sensor line is a cost-effective solution for

applications where precision range-finding, space saving, 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. Additionally, this sensor line allows cost-sensitive designers to choose this precision sensor as a

performance upgrade over other lower performance sensors. The HRUSB-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 compensation for improved accuracy,

superior rejection of outside noise sources, internal 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

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 1
HRUSB-MaxSonar® - EZ™ Series HRUSB-MaxSonar®-EZ™ Series USB Rangefinder, High Resolution Precision MB1403, MB1413, MB1423, MB1433, MB14434 The HRUSB-MaxSonar-EZ sensor line is a cost-effective solution for applications where precision range-finding, space saving, and low-cost are needed. This sensor component module allows users of other more costly 1 mm Resolution precision rangefinders to lower the cost of their systems without sacrificing performance.
PAGE 2
HRUSB-MaxSonar® - EZ™ Series HRUSB-MaxSonar-EZ General Description of Operation The HRUSB-MaxSonar-EZ sensors are a high performance, ultrasonic range finder. The sensor utilizes a USB Micro-B connector for sensor interfacing. The sensor is small in size with holes on the PCB for easy mounting.
PAGE 3
HRUSB-MaxSonar® - EZ™ Series Serial Output Format The sensor output is provided over the COM port (or equivalent) in an ASCII character format. If a target is detected at 480 millimeters the output appears as follows: “R0480 ”. The output is an ASCII capital “R”, followed by four ASCII character digits representing the range in millimeters up to a maximum of 5000 millimeters. This is followed by an ASCII space and a carriage return.
PAGE 4
HRUSB-MaxSonar® - EZ™ Series Sensor Minimum Distance The sensor minimum reported distance is 30-cm (11.8 inches). However, the HRUSB-MaxSonar-EZ will range and report targets to within 1-mm of the front sensor face. Large targets closer than 30-cm will typically range as 300-mm. Range “0” Location The HRUSB-MaxSonar-EZ reports the range to distant targets starting from the back of the sensor PCB as shown in the diagram below.
PAGE 5
HRUSB-MaxSonar® - EZ™ Series Serial Terminal Configuration Con’t Windows Configuration Con’t If the provided software does not automatically find the first available HRUSB-MaxSonar-EZ ultrasonic rangefinder, use the following directions 1. Click the “Settings” option. 2. In the “Serial port settings” window, change the “Port” option to the COM port number assigned to the HRUSB-MaxSonar-EZ ultrasonic rangefinder. For multiple sensor operation, use the following instruction set. 1. Open a terminal window 2.
PAGE 6
HRUSB-MaxSonar® - EZ™ Series Serial Terminal Configuration Con’t USB Latency Computer USB ports have latency and buffer sizes which can change the time between the range readings reported by the HRUSB-MaxSonar-EZ ultrasonic rangefinder. This time delay can be caused by the USB hardware on the computer’s system board, the chipset managing USB communication ports, the age of the computer hardware, the number of devices using USB communication, and by the computers operating system.
PAGE 7
HRUSB-MaxSonar® - EZ™ Series Selecting a HRUSB-MaxSonar-EZ Different applications require different sensors. The HRUSB-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.
PAGE 8
HRUSB-MaxSonar® - EZ™ Series MB1403 HRUSB-MaxSonar®-EZ0™ Beam Pattern and Uses The HRUSB-MaxSonar-EZ0 is the highest sensitivity and widest beam sensor of the HRUSB-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.
PAGE 9
HRUSB-MaxSonar® - EZ™ Series MB1413 HRUSB-MaxSonar®-EZ1™ Beam Pattern and Uses The HRUSB-MaxSonar-EZ1 is an indoor ultrasonic sensor and is a quality, low-cost starting place for a customer not sure of which HRUSB-MaxSonar-EZ sensor to use. It balances the detection of people and other objects with a narrow beam width.
PAGE 10
HRUSB-MaxSonar® - EZ™ Series MB1423 HRUSB-MaxSonar®-EZ2™ Beam Pattern and Uses The HRUSB-MaxSonar-EZ2 is a good compromise between sensitivity and side object rejection. The HRUSB-MaxSonar-EZ2 is an excellent choice for applications that requires slightly less side object detection and sensitivity than the MB1013 HRLV-MaxSonar-EZ1.
PAGE 11
HRUSB-MaxSonar® - EZ™ Series MB1433 HRUSB-MaxSonar®-EZ3™ Beam Pattern and Uses The HRUSB-MaxSonar-EZ3 is a narrow beam sensor with good side object rejection. The HRUSB-MaxSonar-EZ3 has slightly wider beam width than the MB1443 HRUSB-MaxSonar-EZ4 which makes it a good choice for when the HRUSB-MaxSonar-EZ4 does not have enough sensitivity for the application.
PAGE 12
HRUSB-MaxSonar® - EZ™ Series MB1443 HRUSB-MaxSonar®-EZ4™ Beam Pattern and Uses The HRUSB-MaxSonar-EZ4 is the narrowest beam width sensor which is also the least sensitive to side objects offered in the HRUSB-MaxSonar-EZ sensor line. The HRUSB-MaxSonar-EZ4 is an excellent choice when only larger objects need to be detected.
