Data Sheet

Beam Characteristics
The LV-MaxSonar

-EZ0

has the most
sensitivity of the LV-MaxSonar®-EZ™ product
line, yielding a controlled wide beam with high
sensitivity. Sample results for measured beam
patterns are shown below on a 12-inch grid. The
detection pattern is shown for;
(A) 0.25-inch diameter dowel,
note the narrow beam for close small objects,
(B) 1-inch diameter dowel, note the long narrow
detection pattern,
(C) 3.25-inch diameter rod,
note the long controlled detection pattern,
(D) 11-inch wide board moved left to right with
the board parallel to the front sensor face
and the sensor stationary. This shows the
sensor’s range capability.
Note: The displayed beam width of (D) is a
function of the specular nature of sonar and
the shape of the board (i.e. flat mirror like)
and should never be confused with actual
sensor beam width.

-EZ0™
High Performance
Sonar Range Finder
With 2.5V - 5.5V power the LV-MaxSonar
®
-
EZ0™ provides very short to long-range
detection and ranging, in an incredibly
small package. The LV-MaxSonar
®
-EZ0™
detects objects from 0-inches to 254-inches
(6.45-meters) and provides sonar range
information from 6-inches out to 254-inches
with 1-inch resolution. Objects from 0-
inches to 6-inches typically range as 6-
inches. The interface output formats
included are pulse width output, analog
voltage output, and serial digital output.
Features
• Continuously variable gain
for beam control and side
lobe suppression
• Object detection includes
zero range objects
• 2.5V to 5.5V supply with
2mA typical current draw
• Readings can occur up to
every 50mS, (20-Hz rate)
• Free run operation can
continually measure and
output range information
• Triggered operation provides
the range reading as desired
• All interfaces are active
simultaneously
• Serial, 0 to Vcc, 9600Baud,
81N
• Analog, (Vcc/512) / inch
• Pulse width, (147uS/inch)
• Learns ringdown pattern
when commanded to start
ranging
• Designed for protected
indoor environments
• Sensor operates at 42KHz
• High output square wave
sensor drive (double Vcc)
Benefits
• Very low cost sonar
ranger
• Reliable and stable range
data
• Sensor dead zone
virtually gone
• Lowest power ranger
• Quality beam
characteristics
• Mounting holes provided
on the circuit board
• Very low power ranger,
excellent for multiple
sensor or battery based
systems
• Can be triggered
externally or internally
• Sensor reports the range
reading directly, frees up
user processor
• Fast measurement cycle
• User can choose any of
the three sensor outputs
