MB7060 & MB7070
Beam Characteristics
People detection requires high sensitivity, yet minimal side-
lobes requires low sensitivity. The MB7060 and MB7070
balances the detection of people with minimal side-lobes.
Sample results for measured beam patterns are shown below on
a 30-centimeter grid. The detection pattern is shown for;
(A) 0.25-inch diameter dowel,
(B) 1-inch diameter dowel,
(C) 3.25-inch diameter dowel,
(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.

MB7060 & MB7070 Real-time Noise Rejection
While the XL-MaxSonar
®
is designed to operate in the presence of noise, best operation is obtained when noise
strength is low and desired signal strength is high. Hence, the user is encouraged to mount the sensor in such a
way that minimizes outside acoustic noise pickup. In addition, keep the DC power to the sensor free of noise.
This will let the sensor deal with noise issues outside of the users direct control (in general, the sensor will still
function well even if these things are ignored). Users are encouraged to test the sensor in their application to
verify usability.
For every ranging cycle, individual filtering for that specific cycle is applied. In general, noise from regularly
occurring periodic noise sources such as motors, fans, vibration, etc., will not falsely be detected as an object.
This holds true even if the periodic noise increases or decreases (such as might occur in engine throttling or an
increase/decrease of wind movement over the sensor). Even so, it is possible for sharp non-periodic noise
sources to cause false target detection. In addition, *(because of dynamic range and signal to noise physics,) as
the noise level increases, at first only small targets might be missed, but if noise increases to very high levels, it
is likely that even large targets will be missed.
*In high noise environments, if needed, use 5V power to keep acoustic signal power high. In addition, a high acoustic
noise environment may use some of the dynamic range of the sensor, this may decrease sensitivity. For applications with
large targets, consider a part with ultra clutter rejection like the MB7052 or MB7092 or advanced filtering such as the
MB7062 or MB7072.
