MB1003, MB1013, MB1023, MB1033, MB10435
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, large objects closer than 30-cm are typically reported as 30-cm1. 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 30-
cm. Although most users find MaxSonar sensors to work reliably from 0 to 30-cm 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.

Pin Out Description
Pin 1- Temperature Sensor Connection: Leave this pin unconnected if an external
temperature sensor is not used. For best accuracy, this pin is optionally connected to the
HR-MaxTemp temperature sensor. Look up the HR-MaxTemp temperature sensor for
additional information.
Pin 2- Pulse Width Output: This pin outputs a pulse width representation of the distance
with a scale factor of 1uS per mm. Output range is 300uS for 300-mm to 5000uS for
5000-mm. Pulse width output is +/- 1% of the serial data sent.
Pin 3- Analog Voltage Output: On power-up, the voltage on this pin is set to 0V, after
which, the voltage on this pin has the voltage corresponding to the latest measured distance.
This pin outputs an analog voltage scaled representation of the distance with a scale factor of (Vcc/1024) per 5-mm (This
output voltage is referenced to GND, Pin 7). The analog voltage output is typically within ±10-mm of the serial output.
Using a 10-bit analog to digital convertor, one can read the analog voltage bits (i.e. 0 to 1023) directly and just multiply
the number of bits in the value by 5 to yield the range in mm. For example, 60 bits corresponds to 300-mm (where 60 * 5
= 300), and 1000 bits corresponds to 5000-mm (where 1000 * 5 = 5000-mm).
For users of this output that desire to work in voltage, a 5V power supply yields~4.88mV per 5 mm. Output voltage range
when powered with 5V is 293mV for 300-mm, and 4.885V for 5000-mm.
Pin 4- Ranging Start/Stop: This pin is internally pulled high. If this pin is left unconnected or held high, the sensor will
continually measure and output the range data. If held low, the HRLV-MaxSonar-EZ will stop ranging. Bring high for
20uS or longer to command a range reading.
Real-time Range Data: When pin 4 is low and then brought high, the sensor will operate in real time and the first reading
output will be the range measured from this first commanded range reading. When the sensor tracks that the RX pin is low
after each range reading, and then the RX pin is brought high, unfiltered real time range information can be obtained as
quickly as every 100mS.
Filtered Range Data: When pin 4 is left high, the sensor will continue to range every 100mS, but the output will pass
through a 2Hz filter, where the sensor will output the range based on recent range information.
Pin 5-Serial Output: By default, the serial output is RS232 format (0 to Vcc) with a 1-mm resolution. If TTL output is
desired, solder the TTL jumper pads on the back side of the PCB as shown in the photo to the right. For
volume orders, the TTL option is available as no-cost factory installed jumper. The output is an ASCII capital
R”, followed by four ASCII character digits representing the range in millimeters, followed by a carriage
return (ASCII 13). The maximum distance reported is 5000. The serial output is the most accurate of the range
outputs. Serial data sent is 9600 baud, with 8 data bits, no parity, and one stop bit.
V+ Pin 6 - Positive Power, Vcc: The sensor operates on voltages from 2.5V - 5.5V DC. For best operation, the sensor
requires that the DC power be free from electrical noise. (For installations with known dirty electrical power, a 100uF
capacitor placed at the sensor pins between V+ and GND will typically correct the electrical noise.) Please reference page
5 for minimum operating voltage verses temperature information.
GND Pin 7 – Sensor ground pin: DC return, and circuit common ground.
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. Based upon the time of flight, the sensor
then outputs a range reading.

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.
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. Most range readings are accurately reported. If the range readings are affected, the effect is typically less
than 5-mm. This allows users to employ real-time ultrasonic distance sensing without the need for additional supporting
circuitry or complicated user software.
Many acoustic noise sources will have little to no effect on the reported range of the HRLV-MaxSonar-EZ sensors.
However, users are encouraged to test sensor operation in the operating environment.
Sensor Minimum Distance
The sensor minimum reported distance is 30-cm (11.8-inches). The HRLV-MaxSonar-EZ will detect targets to within 1-
mm of the front sensor face. Targets closer than 30-cm will typically range as 300-mm. Targets that are small and
irregular may have inconsistent performance below 30-cm.
Sensor Operation from 30-cm to 50-cm
Because of acoustic phase effects in the near field, objects between 30-cm and 50-cm may experience acoustic phase
cancellation of the returning waveform resulting in inaccuracies of up to 5-mm. These effects become less prevalent as the
target distance increases, and has not been observed past 50-cm. For this reason, industrial users that require the highest
sensor accuracy are encouraged to mount the HRLV-MaxSonar-EZ a minimum of 50-cm from the object.
Range “0” Location
The HRLV-MaxSonar-EZ reports the range to distant targets starting from the back of the sensor PCB as shown in the
diagram below.
In general, the HRLV-MaxSonar-EZ will report the range to the leading edge of the closest detectable object. Target
detection has been characterized in the sensor beam patterns.
Target Size Compensation
Most low cost ultrasonic rangefinders will report the range to smaller size targets as farther than the actual distance. In
addition, they may also report the range to larger size targets as closer than the actual distance.
The HRLV-MaxSonar-EZ sensor line correctly compensates for target size differences. This means that, provided an
object is large enough to be detected, the sensor will report the same distance, typically within 2%, regardless of target
size. Smaller targets can have additional detection noise that may limit this feature. In addition, targets with small or
rounded surfaces may have an apparent distance that is slightly farther, where the distance reported may be a composite of
the sensed object(s). Compensation for target size is applied to all range outputs: pulse width, analog voltage, and serial
RS232 or TTL.

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. If the sensor is used with noise on the supplied power, the
readings may be affected. Typically adding a 100uF capacitor at the sensor between the V+ and GND pins will correct
most power related electrical noise issues.

Temperature Compensation
On Board - Internal Temperature Compensation
The speed of sound in air increases about 0.6 meters per second, per degree centigrade. Because of this, each
HRLV-MaxSonar-EZ is equipped with an internal temperature sensor which allows the sensor to apply a compensation
for speed of sound changes.
The self heating (15mW at 5V, or 8mW at 3.3V) will change the temperature of the sensor by about 1 degree C. The
amount of self heating is dependent upon user mounting.
Most importantly, the actual air temperature of the path between the sensor and the target may not match the temperature
measured at the sensor electronics. Sensors mounted in vertical applications, or applications where the environmental
temperature gradient is severe, may experience a large temperature measurement error which will affect the sensor
accuracy. For example, buildings with a height of 2-meters can have floor to ceiling temperature variations of 5°C or
more. Because of these temperature effects, users desiring the highest accuracy output are encouraged to use a properly
mounted external temperature sensor or to manually account for this measurement error.
HR-MaxTemp® External Temperature Sensor
Although the HRLV-MaxSonar-EZ has an internal temperature sensor; for best accuracy, users are encouraged to use the
optional external temperature sensor. On power-up the HRLV-MaxSonar-EZ will automatically detect an attached
HR-MaxTemp temperature sensor and begin to apply temperature compensation using the external temperature sensor.
The external temperature sensor allows for the most accurate temperature compensation, by eliminating sensor
self-heating from the sensor electronics, and by allowing the user to place the temperature sensor closer to the center of
the acoustic ranging path.
For best results users are encouraged to connect the temperature sensor midway between the HRLV-MaxSonar-EZ and
the expected target distance.

Operating Modes
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 targets distance. Because of this, sensor to
sensor interference must be accounted for. To avoid interference between sensors, chaining can be used to prevent cross-
talk between sensors. This will be necessary when using 3+ sensors depending on mounting and environment.
The recommended chaining method is AN Output Commanded Loop. The first sensor will range, then trigger the next
sensor to range and so on for all the sensors in the array. Once the last sensor has ranged, the array stops until the first
sensor is triggered to range again. Below is a diagram on how to set this up.
Another recommended chaining method is AN Output Constantly Looping. The first sensor will range, then trigger the
next sensor to range and so on for all the sensors in the array. Once the last sensor has ranged, it will trigger the first
sensor in the array to range again and will continue this loop indefinitely. Below is a diagram on how to set this up.

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. The HRLV-MaxSonar-EZ sensors have
three separate outputs that update the range data simultaneously: Analog Voltage, Pulse Width, and Serial Data. Below
are diagrams on how to connect the sensor for each of the three outputs when operating in a single or independent sensor
operating environment.

Operations and Timing Continued
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 240-mm/s.
Users can enter and remain in the Real-Time or Triggered Operation by making sure that after each range cycle the
voltage level on Pin 4 is set low. After the sensor has completed the last reading, then the voltage on Pin 4 is brought high.
This starts a brand new range cycle and the HRLV-MaxSonar-EZ will output the most recent range data without filtering.
Please reference the Real-time Triggered Operation timing diagram for full implementation details.
Readings during triggered operation are less accurate than the 2Hz filtered readings by about +/- 5-mm. Also, because the
range readings are not filtered, noise tolerance can be greatly reduced. Take care to make sure that only one sensor is
sampling range at a time.

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. This
allows users to employ real-time ultrasonic distance sensing without the need for additional supporting circuitry or
complicated user software.
Filtered Operation - Free-Run
The HRLV-MaxSonar-EZ uses an internal 2Hz bandwidth filter to process range data; which reports the latest range every
100mS or 10Hz. This improves the sensors performance for accuracy, noise rejection, and reading to reading stability.
The filtering in the free-run operation also permits additional acoustic and electrical noise tolerance.

Selecting a HRLV-MaxSonar-EZ
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.
_______________________________________________________________________________________________________________________________________
HRLV-MaxSonar®-EZ Beam Patterns
Background Information Regarding our Beam Patterns
Each HRLV-MaxSonar-EZ sensor has a calibrated beam pattern. Each sensor is matched to provide the approximate
detection pattern shown in this datasheet. This allows end users to select the part number that matches
their given sensing application. Each part number has a consistent field of detection so additional
units of the same part number will have similar beam patterns. The beam plots are provided to help
identify an estimated detection zone for an application based on the acoustic properties of a target
versus the plotted beam patterns.
Each beam pattern is a 2D representation of the detection area of the sensor. The beam pattern is
actually shaped like a 3D cone (having the same detection pattern both vertically and horizontally).
Detection patterns for dowels are used to show the beam pattern of each sensor. Dowels are long
cylindered targets of a given diameter. The dowels provide consistent target detection characteristics
for a given size target which allows easy comparison of one MaxSonar sensor to another MaxSonar
sensor.
For each part number, the four patterns (A, B, C, and D) represent the detection zone for a given
target size. Each beam pattern shown is determined by the sensors part number and target size.
The actual beam angle changes over the full range. Use the beam pattern for a specific target at any given distance to
calculate the beam angle for that target at the specific distance. Generally, smaller targets are detected over a narrower
beam angle and a shorter distance. Larger targets are detected over a wider beam angle and a longer range.
People Sensing:
For users that
desire to detect
people, the
detection area to
the 1-inch
diameter dowel, in
general, represents
the area that the
sensor will
reliably detect
people.

Frequently Asked Questions about Our Sensors
We receive many questions about our products and services. This resource offers answers to common inquiries
we receive about our product lines and their application.
Fully Calibrated Beam Patterns
All of our sensors are factory calibrated to provide consistent beam patterns, detection zones, to fit into a wide
variety of applications. In our product lines, each model number comes with a different beam pattern that reflects
the sensitivity and the detection zone of how it sees a target. Additionally, we strive to maintain consistency be-
tween our finished products, and you will see little to no deviation between sensors of the same model. This al-
lows you to have confidence in your final application when using multiple sensors.
Understanding Range Readings
The success of an application may hinge upon knowing the exact location of a target. However, a sensor may
report one meter even if the target is not exactly one meter away from the sensor. Sensor specifications, such as
resolution, precision, and accuracy, help you to understand sensor performance.
How to Use Multiple Ultrasonic Sensors
This guide covers three ways to run your sensors in a Multiple Sensor environment and issues you may face.
