SmartSensor V User Guide
Note
Check the packing slip for actual contents. If any of these items are missing, note
the serial number located on the back of the sensor and contact your distributor.
Additional products may be purchased through your distributor. e following optional
items are not included unless specically ordered (check packing list for actual inventory):
Click 200 surge protector – Prevents electrical surges conducted along underground
cables from damaging the sensor and/or cabinet equipment.
Click 201/202/204 AC to DC converter – A Click 201 provides 1 A of power and is ca-
pable of powering a single sensor; a Click 202 provides 2 A and can power two sensors;
a Click 204 provides 4 A and can power four sensors.
Click 210 circuit breaker – Interrupts power during overload conditions and provides
a convenient way to turn power on and o for the entire system.
Click 230 AC surge protector – Helps protect equipment from current surges on the
power lines.
Selecting a Mounting Location
Consider the following guidelines when selecting a mounting location:
Lane Coverage – Sensor mounting locations should be selected so that all monitored
lanes are within 10 to 200 . (3 to 61 m) and run parallel with each other. If more than
eight lanes need to be simultaneously monitored, consider using multiple sensors or
the SmartSensor HD, which can monitor up to 10 lanes simultaneously.
Parallel Lanes – When the sensor is used to collect both mainline and ramp data, the
pole position should be selected so that the on and o ramp lanes run parallel with the
mainline. If lanes are not parallel, installation of multiple SmartSensor units should be
considered to achieve the sensor’s ±2° side-to-side angle requirement.
Sensors on the Same Pole – When multiple sensors are mounted on the same pole,
they will not be subject to interference if they are congured to operating using dif-
ferent RF channels and are separated vertically by a few feet. e higher sensor would
typically be used for the lanes further from the pole in order to minimize occlusion.

INTRODUCTION  SMARTSENSOR V USER GUIDE 7
Sensors on Opposing Poles – SmartSensor units facing each other on opposing poles
should operate on dierent RF channels and be separated by a 40-. (12.2-m) lateral
oset, if possible.
Line of Sight – e SmartSensor is designed to work accurately in the presence of
barriers, but in general if there is an alternate mounting location that would avoid any
type of structural occlusion, this is preferred. Avoid occlusion by trees, signs, and other
roadside structures.
Neighboring Structures and Parallel Walls – It is also preferred that sensor locations
have a 30-. (9.1-m) lateral separation from overhead sign bridges, overpasses, tun-
nels, parallel walls and parallel-parked vehicles in order to avoid multiple reection
paths from a single vehicle.
Mounting Height – e mounting height should be based upon the oset from the
lanes of interest. For each oset, the minimum, maximum and recommended range
of heights is shown in Table 1.1, found in chapter 1. In general, the range of recom-
mended heights is between 9 and 50 . (2.7 to 15.2 m).
Mounting Oset – e minimum recommended oset from the edge of the rst lane
of interest is 10 . (3 m).
Arterial Locations – Sensor sites on arterials or other roadway segments with regulated
stop lines should be selected at mid-block positions to increase accuracy by increasing
line of sight to stop-and-go vehicles.

Figure I.1 – Portable (left) and Permanent (right) Sensor Stations
Freeway Locations – e SmartSensor V is oen used at permanent ATR stations. e
number of stations along a single roadway and the distance between stations should be
selected to achieve adequate levels of statistical condence. Permanent ATR stations,
which are selected to cover interstate, principal arterial and other national and state

highways, are used to establish seasonal adjustment factors for count data from tempo-
rary collection sites (see Figure I.1).
Cable Lengths – Make sure that you have sucient homerun and sensor cabling. Cable
runs as long as 600 . (182.9 m) using 24 VDC operation and RS-485 communications.
For longer connections, alternate wired and wireless options should be considered.

Table 1.1 – Mounting Height Guidelines
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 (see Figure 1.2):
1 Look up the recommended mounting height from Table 1.1.
2 Insert the stainless steel straps through the slots in the mount bracket.
3 Position the mount on the pole so that the head of the mount is pointing towards the
middle of the lanes of interest.
4 Tighten the strap screws.

16 CHAPTER 1 INSTALLING THE SMARTSENSOR V
Figure 1.2 – Attaching the Mount Bracket to the Pole
Note
Depending on the site and type of trac, the sensor may tend to over- or under-
count. If the sensor is overcounting, reduce the height of the sensor by three ft. (0.9
m) and reconfigure the sensor. If the sensor is undercounting, increase the height of
the sensor by three ft. (0.9 m) and reconfigure. Normally, reducing the height of the
sensor improves performance.
Attaching the Sensor to the Mount Bracket
Use the following steps to securely fasten the sensor to the mount bracket (see Figure 1.3).
1 Align the bolts on the back of the SmartSensor V with the holes in the mounting brack-
et. e 10-pin connector on the SmartSensor V should be pointing towards the ground.
2 Place the lock washers onto the bolts aer the bolts are in the mounting bracket holes.
3 read on the nuts and tighten.

CHAPTER 1  INSTALLING THE SMARTSENSOR V 17
Aligning the Sensor to the Roadway
Follow the steps below to correctly align the SmartSensor V (see Figure 1.4):
Figure 1.4 – Aiming the SmartSensor
1 Aim the front of the sensor at the center of the detection area. Refer to Figure 1.1 as an
illustration of where to aim the sensor.
2 Adjust the side-to-side angle to within approximately ±2° of perpendicular to the ow
of trac.
3 Tighten mounting bracket bolts.
Applying Silicon Dielectric Compound
Use the following steps to correctly apply the silicon dielectric compound:
1 Tear the tab o the tube of silicon dielectric compound.
2 Squeeze about 25% of the silicon into the connector at the base of the SmartSensor V.
Be sure to wipe o any excess compound.
Connecting the 8-conductor Cable
1 Attach the cable connector to the 10-pin connector at the base of the SmartSensor V
as shown in Figure 1.6. e sensor connector is keyed to ensure proper connection;
simply twist the connector clockwise until you hear it click into place.
2 Strap the cable to the pole or run it through a conduit to avoid undue movement from
wind and reduce cable strain.

Once the sensor is installed, it will need to be wired for power and surge protection. is
chapter will explain how to connect lightning surge protection, AC power conversion, DC
power and basic communication.
Wavetronix Click products allow you to quickly and easily connect power and surge protec-
tion to your sensor application. Please refer to the Click quick-reference guides for more
comprehensive product instructions. Chapter 9 contains information on how Click prod-
ucts make the sensor compatible with all standard control cabinets.
A pinout diagram showing the sensor cable’s pinout and appropriate connection points can
be found in Appendix A of this document.
Connecting Lightning Surge Protection
e rst item of concern is surge protection. e SmartSensor V has onboard surge protec-
tion, meaning that unlike the SmartSensor HD, the V does not require a pole-mount box;
the only external surge protection device, along with power and communication devices,
will be stored in the main trac cabinet.
