Introduction
Complete the steps below to integrate the Wavetronix SmartSensor Matrix system into a signalized intersection. If you need technical support, please contact Wavetronix Technical Services at 801.764.0277. For more

e following are the suggested Matrix mounting locations:
1 The back side of mast arm – Allows the
sensor to be placed near the lanes of interest
and may be the best location option for
wide approaches. Mount the sensor toward
the end of the arm, to avoid occlusion from
passing vehicles, but make there’s at least
6 . (1.8 m) lateral seperation between the
sensor and the rst lane of interest.
2 The far side of approach – Usually mount-
ed 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 – Typically best if detecting the le turn lane is less important; also allows
you to mount the sensor high enough to avoid occlusion.
Note. e sensor must be at least 6 . (1.8 m) from the rst lane of interest—that is, if you drew a line from
the sensor to the ground, that line should hit the ground at least 6 . from the rst lane you need to detect.

Use the following guidelines to determine the best mounting height:
˽ e sensor should be placed at a height of roughly 20 ., give or take 5 . (6.1 ± 1.5 m).
˽ e maximum recommended mounting height is 60 . (18.2 m). e minimum recommended mount-
ing height is 12 . (3.6 m). (e farther you install the sensor from the rst lane of interest, the higher
the sensor should be mounted.)
˽ Take into consideration the sensor’s footprint, which reaches 140 . (42.7 m) from the sensor. Place the
sensor so that the footprint covers all the areas of interest. Be aware that 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.
˽ 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 bet-
ter with a lower mounting position.
To attach the mount bracket to the pole:
1 Insert the stainless steel straps through the slots in the mount bracket.
2 Position the mount on the pole so the mount head points toward the lanes of
interest at a 45° angle.
3 Tighten the strap screws.
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 aer the bolts are in the mount bracket holes.
3 read on the nuts and tighten.
Align sensor to roadway

e sensor’s eld of view fans out 45° to both sides. You will usually want to position the radar beam so that
its 90° footprint covers all lanes approaching the stop bar.
Also, the eld of view’s front edge must be aligned to provide some coverage beyond the stop bar so you can
detect vehicles that don’t stop at or behind the stop line, as well as vehicles exiting queues.
1 Adjust the side-to-side angle so the front edge of the eld of view
provides a view downstream of the stop bar.
2 Tilt the sensor down to aim it 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 signicant grade.
