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, with large
objects closer than 30-cm are typically reported as 30-cm
1
. The interface output formats are pulse width, analog
voltage, and serial digital in either RS232 or TTL. Factory calibration is standard.

Precision Range Sensing
•
Range-finding at a fraction of the cost of
other precision rangefinders
•
Reading-to-reading stability of 1-mm at 1
-meter is typical
•
Accuracy is factory-matched at 1-meter
to 0.1% providing a typical large target
accuracy of 1% or better for most
voltages and uses
2
•
Calibrated acoustic detection zones
allows selection of the part number that
matches a specific application
•
Compensation for target size variation
and operating voltage range
•
Standard internal temperature
compensation and optional external
temperature compensation
Range Outputs
•
Pulse width, (1uS/mm)
•
Analog Voltage, (5mm resolution)
•
Serial, (RS232 or TTL using solder-able
jumper or volume orders available as no-
cost factory installed jumper)
Easy to Use Component
Module
•
Gracefully handles other ultrasonic
sensors

Triggered operation yields a real-time
•
100mS measurement cycle
•
Free run operation uses a 2Hz filter, with
100mS measurement and output cycle
•
Actual operating temperature range from
–40°C to +65°C, Recommended
operating temperature range from -15°C
to +65°C, provided proper frost
prevention is employed

•
Nominal current draw of 2.5mA at 3.3V,
and 3.1mA at 5V
•
Low current draw reduces current
drain
for battery operation
• Fast first reading after power-up
eases battery requirements

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.
