LV-MaxSonar

-EZ™ Series

High Performance Sonar Range Finder

MB1000, MB1010, MB1020, MB1030, MB1040

With 2.5V - 5.5V power the LV-MaxSonar-EZ provides very short to long-range

detection and ranging in a very small package. The LV-MaxSonar-EZ detects objects

from 0-inches to 254-inches (6.45-meters) and provides sonar range information from 6-

inches out to 254-inches with 1-inch resolution. Objects from 0-inches to 6-inches typically range as 6-inches

. The

interface output formats included are pulse width output, analog voltage output, and RS232 serial output. Factory

calibration and testing is completed with a flat object.

Close Range Operation

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

6 inches. Although most users find MaxSonar sensors to work reliably from 0 to 6 inches 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.

LV-MaxSonar® - EZ™ Series LV-MaxSonar®-EZ™ Series High Performance Sonar Range Finder MB1000, MB1010, MB1020, MB1030, MB10402 With 2.5V - 5.5V power the LV-MaxSonar-EZ provides very short to long-range detection and ranging in a very small package. The LV-MaxSonar-EZ detects objects from 0-inches to 254-inches (6.45-meters) and provides sonar range information from 6inches out to 254-inches with 1-inch resolution. Objects from 0-inches to 6-inches typically range as 6-inches1.
PAGE 2
LV-MaxSonar® - EZ™ Series About Ultrasonic Sensors Our ultrasonic sensors are in air, non-contact object detection and ranging sensors that detect objects within an area. These sensors are not affected by the color or other visual characteristics of the detected object. Ultrasonic sensors use high frequency sound to detect and localize objects in a variety of environments. Ultrasonic sensors measure the time of flight for sound that has been transmitted to and reflected back from nearby objects.
PAGE 3
LV-MaxSonar® - EZ™ Series cancellation of the returning waveform resulting in inaccuracies of up to 2-inches. These effects become less prevalent as the target distance increases, and has not been observed past 20-inches. General Power-Up Instruction Each time the LV-MaxSonar-EZ is powered up, it will calibrate during its first read cycle. The sensor uses this stored information to range a close object. It is important that objects not be close to the sensor during this calibration cycle.

LV-MaxSonar® - EZ™ Series Using Multiple Sensors in a single system When using multiple ultrasonic sensors in a single system, there can be interference (cross-talk) from the other sensors. MaxBotix Inc., has engineered and supplied a solution to this problem for the LV-MaxSonar-EZ sensors. The solution is referred to as chaining. We have 3 methods of chaining that work well to avoid the issue of cross-talk. The first method is AN Output Commanded Loop.

LV-MaxSonar® - EZ™ Series Independent Sensor Operation The LV-MaxSonar-EZ sensors have the capability to operate independently when the user desires. When using the LV-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. The LV-MaxSonar-EZ sensors have three separate outputs that update the range data simultaneously: Analog Voltage, Pulse Width, and RS232 Serial.

LV-MaxSonar® - EZ™ Series MB1000 LV-MaxSonar-EZ0 The LV-MaxSonar-EZ0 is the highest sensitivity and widest beam sensor of the LV-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 8
LV-MaxSonar® - EZ™ Series MB1010 LV-MaxSonar-EZ1 The LV-MaxSonar-EZ1 is the original MaxSonar product. This is our most popular indoor ultrasonic sensor and is a great low-cost general-purpose sensor for a customer not sure of which LV-MaxSonar-EZ sensor to use.
PAGE 9
LV-MaxSonar® - EZ™ Series MB1020 LV-MaxSonar-EZ2 The LV-MaxSonar-EZ2 is a good compromise between sensitivity and side object rejection. The LV-MaxSonar-EZ2 is an excellent choice for applications that require slightly less side object detection and sensitivity than the MB1010 LV-MaxSonar-EZ1. MB1020 Features and Benefits  Great for applications where the MB1010 is too sensitive.
PAGE 10
LV-MaxSonar® - EZ™ Series MB1030 LV-MaxSonar-EZ3 The LV-MaxSonar-EZ3 is a narrow beam sensor with good side object rejection. The LV-MaxSonar-EZ3 has slightly wider beam width than theMB1040 LV-MaxSonar-EZ4 which makes it a good choice for when the LV-MaxSonar-EZ4 does not have enough sensitivity for the application.
PAGE 11
LV-MaxSonar® - EZ™ Series MB1040 LV-MaxSonar-EZ4 The LV-MaxSonar-EZ4 is the narrowest beam width sensor that is also the least sensitive to side objects offered in the LV-MaxSonar-EZ sensor line. The LV-MaxSonar-EZ4 is an excellent choice when only larger objects need to be detected.
