HRUSB-MaxSonar-EZ General Description of Operation
The HRUSB-MaxSonar-EZ sensors are a high performance, ultrasonic range finder. The sensor utilizes a USB Micro-B
connector for sensor interfacing. The sensor is small in size with holes on the PCB for easy mounting. The
HRUSB-MaxSonar-EZ sends serial data to the users operating system which can then be read from the registered COM
port (or equivalent) using a terminal program or read directly from the operating system (OS) by using the appropriate
software functions.
The HRUSB-MaxSonar-EZ is powered by the USB connection and begins operating after the USB handshaking has
occurred. The range information is sent continuously to the users operating system (OS) and is available to be read at any
time.
Connection is handled automatically by device drives that are available for most OS's (Windows XP and later, Linux
Kernel 2.6 and later, Mac OS X and later.) The steps taken to perform the configuration varies slightly by the target OS
however the general operation and the data sent by the sensor remains the same. Configuration of the
HRUSB-MaxSonar-EZ can be seen in the Serial Terminal Configuration section.

Accessing the USB Serial Output — Quick Setup
A terminal program is the easiest method of reading the sensor output. Software downloads and step by step instructions
are available at http://www.maxbotix.com/terminal.htm

HRUSB-MaxSonar-EZ General Power-Up Instruction
Each time the HRUSB-MaxSonar-EZ takes a range reading, it calibrates itself. The sensor then uses this data to range
objects. If the temperature or humidity changes during sensor operation; the sensor will continue to function normally
over the rated temperature range while applying compensation for speed of sound changes caused by temperature.

Operation Temperature and environments
The recommended operating temperature is 0C to 65C. The recommended dry storage temperature is –40C to +65C.
Storage or operation in wet or moist environments may result in sensor damage.

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.
