Although most users find MaxSonar sensors to work reliably from 0 to 2cm 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. _______________________________________________________________________________________________________________________________________ Warning: Personal Safety Applications We do not recommend or endorse this product be used as a component in any personal safety applications.

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 20uS for 20-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, Vobserved, is set to 0V. After which, the voltage on this pin has the voltage corresponding to the latest measured distance. This distance can be calculated with the following equation: distance = [Vobserved / ((Vcc/1024) * 6)] - 300. (This output voltage is referenced to GND, Pin 7.) The analog voltage output is typically within ±10-mm of the serial output. Using a 10bit analog to digital convertor, one can read the analog voltage bits (i.e. 0 to 1023) directly and multiply the number of bits in the value by 6 and subtract 300 to yield the range in mm. For example, 54 bits corresponds to 24-mm where (54 * 6) - 300 = 24-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-ShortRange-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. 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-ShortRange-EZ takes a range reading, it calibrates itself. The sensor 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.

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 affect on the reported range of the HRLV-ShortRange-EZ sensors. However, users are encouraged to test sensor operation in the operating environment. Sensor Minimum Distance The sensor minimum reported distance is 2-cm (0.8 inches). However, the HRLV-ShortRange-EZ will detect targets to within 1-mm of the front sensor face. Large targets closer than 2-cm will typically range as 20-mm. Sensor Operation from 2-cm to 50-cm Because of acoustic phase effects in the near field, objects between 2-cm and 50-cm may experience acoustic phase cancellation of the returning waveform resulting in inaccuracies of up to 3-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-ShortRange-EZ from objects that are farther than 50-cm. Range “0” Location The HRLV-ShortRange-EZ reports the range to distant targets starting from the front of the transducer. Range Zero 0.0-mm The range is measured from the front of the transducer to the target Target Face In general, the HRLV-ShortRange-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-ShortRange-EZ sensor line correctly compensates for target size differences. 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 outputs: pulse width, analog voltage, and serial RS232 or TTL. Selecting a HRLV-ShortRange-EZ The HRLV-ShortRange-EZ product line offers varied sensitivity to allow you to select the best sensor to meet your needs. The diagram below 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-ShortRange-EZ-Beam Patterns.

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. 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. _______________________________________________________________________________________________________________________________________ Mechanical Dimensions _______________________________________________________________________________________________________________________________________ A 1.498” 38.05-mm D 0.104” 2.64-mm G 0.700” 17.78-mm K 0.125 dia. 3.18-mm K 0.125 dia. 3.18-mm O 0.580” 13.97-mm B 0.875” 22.23-mm E 0.670” 17.02-mm H 0.510” 12.95-mm L 0.040” dia. 1.02-mm L 0.040” dia. 1.02-mm P 0.700” 17.78-mm C 0.102” 2.59-mm F 1.210” 30.73-mm I 0.069” 1.75-mm M 0.053” 1.35-mm M 0.053” 1.35-mm Q 0.343” 8.71-mm J 0.169” 4.29-mm N 0.625” 15.88-mm N 0.625” 15.88-mm R 0.427” 10.85-mm Weight 8 Grams 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 HRLVShortRange-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 affects, 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-ShortRange-EZ has an internal temperature sensor; for best accuracy users are encouraged to use the optional external temperature sensor. On power-up the HRLV-ShortRange-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 connect the temperature sensor midway between the HRLV-ShortRange-EZ and the expected target. MaxBotix® Inc.

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. 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. Pull RX pin high on the first sensor for at least 20uS to (96mS),and the rest of the sensors will read the range in sequence. Wire AN pin to AD input Wire AN pin to AD input Wire AN pin to AD input 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. Pull RX pin high on the first sensor for at least 20uS to 96mS), Then the micro controller will have to return it’s pin to a high impedance state so the TX output from the last sensor will make it’s way to the RX of the first sensor.

Independent Sensor Operation The HRLV-ShortRange-EZ sensors have the capability to operate independently when the user desires. When using the HRLV-ShortRange-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-ShortRange-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. Ground or Circuit Common Ground or Circuit Common Ground or Circuit Common Supply Voltage of 2.5 to 5.5 volts Supply Voltage of 2.5 to 5.5 volts Supply Voltage of 2.5 to 5.5 volts Wire AN pin to use with an ADC Wire PW pin to use the PW output Wire Serial pin to use R232 or TTL output _______________________________________________________________________________________________________________________________________ Operations and Timing ~60 ms MaxBotix® Inc.

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. 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-ShortRange-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. MaxBotix® Inc.

Many acoustic noise sources will have little to no affect on the reported range of the HRLV-ShortRangeEZ 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-ShortRange-EZ uses an internal 2Hz bandwidth filter to process range data; which reports the latest range every 100mS or 10Hz. This improves the sensor’s 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. Output): MB16X3 Output): MB16X4 MaxBotix® Inc.

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. People Sensing: For users that desire to detect people, the detection area to the 1-inch diameter dowel, in Each beam pattern is a 2D representation of the detection area of the sensor. The beam pattern is general, represents actually shaped like a 3D cone (having the same detection pattern both vertically and horizontally). the area that the 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 sensor will for a given size target which allows easy comparison of one MaxSonar sensor to another MaxSonar reliably detect people. 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 sensor’s 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.

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 between our finished products, and you will see little to no deviation between sensors of the same model. This allows 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.
