The HRXL-MaxSonar-WR sensor line is a cost-effective solution for applications requiring

precision range-finding, low-voltage operation, space saving, low-cost, and IP67 rating for weather

resistance.

The HRXL-MaxSonar-WR sensor line provides high accuracy and high resolution ultrasonic proximity

detection and ranging in air. 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. The HRXL-MaxSonar-WR/WRC models are available

in 5-meter or 10-meter models. This ultrasonic sensor detects objects from 1-mm and ranges to objects from 30-cm* to

maximum range. Objects closer than 30-cm* are typically reported as 30-cm*. The interface output formats are pulse

width, analog voltage, and digital serial in either RS232 (MB7360 series) or TTL (MB7380 series). Factory calibration

is standard.

*For select sensors this distance is 50-cm, refer to pages 4 and 5.

Close Range Operation

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

50cm. Although most users find MaxSonar sensors to work reliably from 0 to 50cm 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.

HRXL-MaxSonar-WR Pin Out

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. Some additional information for the temperature

sensor can be found on page 10 of the datasheet.

Pin 2- Pulse Width Output:

This pin outputs a pulse width representation of the distance with a scale factor of 1uS per mm. The

pulse width output is sent with a value within 0.5% of the serial output.

Pin 3- Analog Voltage Output:

This pin outputs a single ended analog voltage scaled representation of the distance. This output

is referenced to the sensor ground and Vcc. After the ~50mS power up initialization, the voltage on this pin is set to a low voltage.

Once the sensor has completed a range reading the voltage on this pin is set to the voltage corresponding to the latest measured

distance.

The 5-meter sensors (MB7360, MB7369, MB7380, and MB7389) use a scale factor of (Vcc/5120) per 1-mm. The distance is output

with a 5-mm resolution. The analog voltage output is typically within ±5-mm of the serial output.

The 10-meter sensors (MB7363, MB7366, MB7383, and MB7386) use a scale factor of (Vcc/10240) per 1-mm. The distance is output

with a 10-mm resolution. The analog voltage output is typically within ±10-mm of the serial output.

Using a 10-bit analog to digital converter with the 5-meter sensors, one can read the analog voltage counts (i.e. 0 to 1023) directly and

just multiply the number of counts in the value by 5 to yield the range in mm. For example, a converted value of 60 corresponds to

300-mm (where 60 x 5 = 300), and 1000 counts corresponds to 5,000-mm (where 1000 x 5 = 5,000-mm).

Using a 10-bit analog to digital converter with the 10-meter sensors, one can read the analog voltage counts (i.e. 0 to 1023) directly

and just multiply the number of counts in the value by 10 to yield the range in mm. For example, 30 counts corresponds to 300-mm

(where 30 x 10 = 300), and 1000 counts corresponds to 10,000-mm (where 1000 x 10 = 10,000-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 HRXL-MaxSonar-WR will stop ranging. Bring high for 20uS or longer

to command a range reading.

Filtered Range Data:

When pin 4 is left high on the sensors, the sensors will continue to range. The data that is output includes a

filter for increased accuracy. The sensors will output the range based on recent range information. The filter does not affect the speed

at which data is made available to the user but instead allows for more consistent range information to be presented. For sensor

specific timing and filter information refer to pages 8 and 9.

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. For timing information please

refer to pages 8 and 9.

Pin 5-Serial Output:

The MB736X sensors have an RS232 data format (with 0V to Vcc levels) and the MB738X sensors have a

TTL outputs. 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 range reported is 4999 mm (5-meter models) or 9998 mm (10-meter

models). A range value of 5000 or 9999 corresponds to no target being detected in the field of view.

The serial data format is 9600 baud, 8 data bits, no parity, with one stop bit (9600-8-N-1).

Because the data is presented in a binary data format, the serial output is most accurate .

V+ Pin 6 -

Positive Power, Vcc: The sensor operates on voltages from 2.7V - 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 10 & 11 for minimum operating voltage

verses temperature information.

GND Pin 7 –

Sensor ground pin: DC return, and circuit common ground.

Series

Base sensor (MB7360 and MB7380)

The MB7360 and MB7380 are the base model of the HRXL-MaxSonar-WR sensor line. These sensors are recommended

for users unsure of which sensor to use in their application. All other sensors in this series are based off of these sensor

models. The additional features are mentioned in their respective sections below.

_______________________________________________________________________________________________________________________________________

HRXL-MaxSonar-WRLS (MB7363 and MB7383)

The HRXL-MaxSonar-WRLS sensors are 10 meter sensors with a higher sensitivity than other HRXL-MaxSonar-WR

products. This sensor is recommended for applications in which objects do not reflect enough ultrasonic sound, such as

people, to be detected. Users are encouraged to test the sensor in their application to verify usability.

_______________________________________________________________________________________________________________________________________

HRXL-MaxSonar-WRL (MB7366, MB7386)

The HRXL-MaxSonar-WRL sensors are the 10-meter version of the HRXL-MaxSonar-WR sensors.

_______________________________________________________________________________________________________________________________________

HRXL-MaxSonar-WRM (MB7369 and MB7389)

The HRXL-MaxSonar-WRM sensors are equipped with filtering firmware which allows the sensor to ignore smaller

targets and noise, and still report the target that gives the largest acoustic return. (The sensor will also reject periodic

noise, even noise that has a higher amplitude than the acoustic return from the target.) This gives users the flexibility to

consistently range larger targets in the presence of clutter and noise. If the largest target is removed from the field of view,

the HRXL-MaxSonar-WRM will switch to the target that gives the next largest detectable return.

The HRXL-MaxSonar-WRM sensors were designed for applications where users were concerned with ranging the

distance to large flat targets (such as in a water tank). This stands in contrast to other HRXL-MaxSonar-WR sensors

which will report the distance to the first detectable target.

In general, the HRXL-MaxSonar-WRM will select the largest target from its field of view and report its range. Even so,

objects up close may provide significantly greater returns over distant objects. Users are encouraged to test the sensor in

their application to verify usability.

When targets are of similar amplitude reflections, preference is given to the closest target.
