 SmartSensor Matrix Package
 Selecting a Mounting Location
e Wavetronix SmartSensor Matrix™ is a stop bar presence detector designed for use at
signalized intersections (see Figure I.1). e SmartSensor Matrix detects vehicles through
the use of a 24.125 GHz (K band) operating radio frequency. Using what is classied as
frequency modulated continuous wave (FMCW) radar, SmartSensor Matrix detects and
reports vehicle presence in as many as 10 lanes simultaneously.
Figure I.1 – Wavetronix SmartSensor Matrix
SmartSensor Matrix is a rst-of-its-kind radar stop bar detector with Radar Vision™. It
delivers the reliability of radar and the simplicity of non-intrusive detection for stop bar
presence detection. In many situations, the sensor is installed on the roadside in order to
prevent the need for lane closures and trac control. Once the unit is installed, the congu-

ration process is quick and easy. Aer installation, the sensor will require little or no on-site
maintenance and can be remotely congured.
is user guide outlines the step-by-step process of installing and conguring the Smart-
Sensor Matrix. Any questions about the information in this guide should be directed to
Wavetronix or your distributor.
SmartSensor Matrix Package
A standard SmartSensor Matrix package may contain the following items:
SmartSensor Matrix detector(s) with installed sensor backplate
Sensor mounting kit(s)
SmartSensor 6-conductor cable(s)
Intersection preassembled backplate
Click 112/114 detector rack card(s) with patch cable(s)
Click 104 four-channel DIN rail contact closure module
SmartSensor Manager Matrix (SSMM) soware
SmartSensor Matrix User Guide
Note
Instead of the intersection preassembled backplate, you may be using the Click 600
cabinet interface device, the preassembled 19-inch rack, or the segmented preas-
sembled backplate. The coming chapters will note installation dierences between
these devices and the preassembled backplates where applicable.
SmartSensor Matrix system options include (see Figure I.2):
AC power conversion – Provides reliable power for the sensors and backplate com-
ponents. is option is normally recommended instead of the DC surge protection
because it will not burden the existing DC power modules.
Remote IP connection – Provides a way (via a Click 301 serial to Ethernet converter)
to connect to the sensor from a remote location. e Click 301 is recommended for
remote management.

SmartSensor Matrix systems provide a control bridge to manage all connected
SmartSensor and Click devices. The control bridge is completely separate from the
dedicated channels used for communication of contact closure detection calls in real
time.
Selecting a Mounting Location
Consider the following guidelines when selecting a mounting location for each SmartSen-
sor Matrix:
Corner radar – e SmartSensor Matrix is a corner radar device with a panoramic
90°, 140-. (42.7-m) view (see Figure I.3). e sensor’s mounting location should be
selected so that all stop bar detection zones on an approach are within a 6–140-.
(1.8–42.7-m) radial distance.

140 ft
Sensor Pole

Figure I.3 – Corner Radar
Line of sight – Position the sensor so that it will be able to detect the entire area of
interest. Avoid occlusion by installing the sensor away from trees, signs and other road-
side structures.
Detection coverage – Position the sensor so that it will be able to reach all the specied
stop bar detection zones. e sensor will oen work better if you position it so that it
tracks vehicles for several feet before the rst zone in each lane. If the sensor has a view
several feet beyond the stop bar, it is more likely to accurately detect queue dissipation.
Closest roadside – Mount the sensor on the side of the road closest to the lanes of pri-
mary interest. Always mount the sensor high enough to prevent trac from occluding
approaching vehicles.
Mounting height – A minimum height of 12 . (3.6 m) is recommended. Mounting
the sensor higher will generally improve line of sight and decrease the possibility of
occlusion.
Mounting oset – A minimum oset of 6 . (1.8 m) to the rst lane of interest is
required.
Redundant detection – It is possible to have multiple sensors monitoring the same
approach. Multiple sensors are needed when zones are spread over more than 140 .
(42.7 m).
Sensor proximity – When multiple sensors are mounted at the same intersection, in-
terference can be avoided by conguring each sensor to operate on a unique RF chan-
nel.
Departing lanes – ere is usually no need to view trac in departing lanes or to con-
gure departing lanes. However, if they are congured, then the stop bar should not
be congured.
Suspended electrical cables – e sensor is designed to work in the presence of sus-
pended power lines and other electrical cables. However, these cables should be at least
10 . (3 m) away from the front of the sensor.
Neighboring structures and parallel walls – e sensor should not be mounted with

INTRODUCTION  SMARTSENSOR MATRIX USER GUIDE 9
signs or other at surfaces directly behind it. is will help reduce multiple reection
paths from a single vehicle.
Cable length – Make sure that you have sucient homerun and sensor cabling. Cable
runs as long as 500 . (152.4 m) can be achieved using 24 VDC operation and the sys-
tem’s native RS-485 communications. If your application requires a cable length longer
than 500 . (152.4 m), contact Wavetronix Technical Services for assistance.
e SmartSensor Matrix should be mounted using one of the following options (see Figure
I.4):

➋➊
Figure I.4 – Mounting locations
1 The back side of mast arm – is location allows the sensor to be placed near the lanes
of interest and may be the best location option for wide approaches. If you mount the
sensor on the back side of a mast arm, mount it near the end of the arm to reduce the
possibility of the mast arm or departing trac occluding approaching vehicles.
2 The far side of approach – e sensor is usually mounted on a corner vertical mast
pole or strain pole. If the sensor is mounted on a vertical pole with a mast arm, you
can usually avoid occlusion by mounting the sensor away from or below the mast arm.
3 The near side of approach – is mounting location is typically best if detecting the
le turn lane is less important. is location also allows you to mount the sensor high
enough to avoid occlusion.
Other mounting locations may be possible if these are not available at your intersection.
Contact Wavetronix Technical Services for assistance if you would like to use an alternative
mounting location.

Warning
Use caution when installing any sensor on or around active roadways. Serious injury
can result when installation is performed using methods that are not in accordance
with authorized local safety policy and procedures. Always maintain an appropriate
awareness of the trac conditions and safety procedures as they relate to specific
locations and installations.
Sensor Mounting Guidelines
e sensor is fairly insensitive to mounting height, but every site will vary based on lane
conguration and the presence of barriers and structures in and around the detection area.
e following table will help you determine how high to mount the sensor (see Table 1.1).
ese gures are only suggestions, but a good rule to follow is—the farther away the rst
lane is to the sensor, the higher you will want to mount the sensor to avoid occlusion.
Closest Lane Sensor Height
6–15 feet 12–25 feet
15–50 feet 15–25 feet
> 50 feet 25–60 feet
Table 1.1 – Suggested Mounting Guidelines
Note
In certain conditions, lanes that have stop bars or detection zones placed at extended
range may show some loss in performance, even with a proper mounting height. This
is more apparent at locations with many travel lanes or where detection zones are
placed near the far edges of detection. If you have any questions regarding the use
of SmartSensor Matrix at a particular location, please contact Wavetronix Technical
Services or your authorized Wavetronix dealer for more information.
Use the following guidelines to determine the best mounting height, then place your sensor
accordingly:
In general, the sensor should be placed at a height of roughly 20 . (6.1 m), give or take
5 . (±1.5 m).
e maximum recommended mounting height for the SmartSensor Matrix is 60 .
(18.2 m). e minimum is 12 . (3.6 m). Placing the sensor above or below these limits
will adversely aect detection accuracy.

CHAPTER 1  INSTALLING THE SMARTSENSOR MATRIX 15
Take into consideration the sensor’s eld of view, which reaches 140 . (42.7 m) from
the sensor. Place the sensor so that the eld of view covers all the areas of interest.
e mast arm is frequently a good place to mount the sensor.
e mounting position should have a clear view of the detection area. Poles, mast arms,
signal heads, or other objects should not block the view of the detection area.
Placing the sensor higher will result in less occlusion. Placing it lower could result in
more occlusion. However, if the nearest detection area is less than about 20 . (6.1 m)
away, the sensor may perform better with a lower mounting position.
Note
It is possible to mount the sensor lower than 12 ft. (3 m) in some scenarios. The sen-
sor will continue to detect vehicles at lower heights, but missed detections due to
occlusion may become more prevalent or problematic in lanes that are farther away
from the sensor.
Attaching the Mount Bracket to the Pole
Before attaching the mount bracket to the pole, rst make sure that your cables are long enough
to reach the sensor height and to stretch across the distance from the sensor to the cabinet.
Follow the steps below to correctly attach the mount to the pole:
1 Insert the stainless steel straps through the slots in the mount bracket.
2 Position the mount on the pole so that the head of the mount is pointing toward the
lanes of interest at about a 45° angle.
3 Tighten the strap screws.
Figure 1.1 – Attach the Mount Bracket to the Pole
e sensor double-swivel mount may need to be adjusted later to ne-tune the alignment.

16 CHAPTER 1 INSTALLING THE SMARTSENSOR MATRIX
One swivel joint is used to pan the sensor eld of view le or right and the other swivel joint
is used to tilt the sensor down towards the roadway. If you are not using the double swivel-
mount, make sure the pole straps are adjustable at this point in the installation process.
Attaching the Sensor to the Mount Bracket
Use the following steps to securely fasten the sensor to the mount bracket:
1 Align the bolts on the sensor’s backplate with the holes in the mount bracket. e eight-pin
connector receptacle on the bottom of the sensor should be pointing towards the ground.
2 Place the lock washers onto the bolts aer the bolts are in the mount bracket holes.
3 read on the nuts and tighten (see Figure 1.2)
Figure 1.2 – Attach the Sensor to the Mount Bracket
Caution
Do not over-tighten the fasteners.
Aligning the Sensor to the Roadway
e sensor’s beams fan out 45° to the le and 45° to the right, creating a 90° corner radar
eld of view. In most applications, you will want to position the corner radar so that its 90°
footprint covers all lanes approaching the stop bar (see Figure 1.3).

Figure 1.3 – Corner Radar Field of View Position
To visualize the extent of the sensor eld of view, the 90° eld of view is imprinted on the top
and bottom of the sensor case. If more of a visual indicator is needed, then a square framing
tool (e.g. raer square) or other tool with a right angle can be held above the sensor. By look-
ing down both edges of the tool, you can visualize the extent of the radar’s coverage.
Usually the front edge of the sensor’s eld of view is aligned to provide coverage beyond
the stop bar (see Figure 1.4). is allows you to place detection zones beyond the stop bar
to detect those vehicles that do not stop at or behind the stop line and will also allow the
sensor to see vehicles exiting queues. If the sensor pole is upstream from the stop bar, it is
recommended to pan in the direction of the stop bar.
Front edge of field of view
Figure 1.4 – Sensor Aligned by Rotating Towards the Stop Bar
Use the following steps to correctly align the SmartSensor Matrix:
1 Adjust the side-to-side angle so that the front edge of the eld of view provides a view

18 CHAPTER 1 INSTALLING THE SMARTSENSOR MATRIX
downstream of the stop bar.
2 Tilt the sensor down so it is aimed at the center of the lanes of interest.
3 If necessary, rotate the sensor so that the bottom edge of the sensor is parallel with the
roadway. is is necessary where the intersection approach has a signicant grade.
Note
To fully complete sensor alignment, you will need to connect to the Matrix sensor
using SmartSensor Manager Matrix and verify that your alignment is detecting the
vehicles in the lanes of interest (see Chapter 8).
Applying the Silicon Dielectric Compound
Use the following steps to correctly apply the silicon dielectric compound to the cable con-
nector:
1 Tear the tab o of the tube of silicon dielectric compound.
2 Squeeze about 25% of the silicon onto the pins of the receptacle side of the connector
at the base of the SmartSensor Matrix (see Figure 1.5). Be sure to wipe o any excess
compound.
Figure 1.5 – Connector Receptacle (left) and Grounding Lug (right)
Connecting the SmartSensor 6-conductor Cable
e next step is to plug the SmartSensor 6-conductor cable into the connector. e sensor
connector is keyed to ensure proper connection (see Figure 1.6); simply twist the plug end
of the connector clockwise until you hear it click into place. To avoid undue movement
from the wind, strap the 6-conductor cable to the pole or run it through a conduit, but leave
a small amount of slack at the top of the cable to reduce cable strain. Route the cable from
the sensor location back to the main trac cabinet.

CHAPTER 1  INSTALLING THE SMARTSENSOR MATRIX 19
Figure 1.6 – Sensor 6-conductor Cable Connector
To set up your network in an orderly fashion, it is recommended that labeling be used
on the service end of each SmartSensor 6-conductor cable. A convenient way to label the
cables is to mark the last seven digits of the serial number on each sensor and the direction
of trac monitored (see Figure 1.7).
Figure 1.7 – Service End Labeling
Grounding the Sensor
e SmartSensor Matrix must now be grounded:
1 Connect a grounding wire to the grounding lug on the bottom of the sensor (see Figure
1.5).
2 Connect the other end of the grounding wire to the earth ground for the pole that the
sensor is mounted on. Do not attempt to run the grounding wire back to the main
trac cabinet.
