1 PLACEPOD OVERVIEW
PlacePod™ is an IoT-enabled smart parking sensor for on-street and off-street municipal and
private parking management. It solves the most mission-critical aspects of parking
management: accurate, real-time vehicle detection and location of available parking spaces.
Key Features & Benefits
•Includes the industry’s most accurate magnetic sensing system for vehicle detection
with the combination of PNI’s high-performance magnetic sensor and vehicle detection
algorithms that accurately detect the presence or absence of a car in a parking space.
•Includes a built-in LoRa radio that communicates to a gateway or base station with
complete LPWAN compatibility.
•Sensors and algorithms are finely tuned for ultra-low power consumption, providing
continuous vehicle detection without missing a parking event.
•Capability for wireless software updates using Bluetooth Low Energy (BLE) via PNI’s
mobile application.
•Battery capacity = 8.1 Ah

2 PRE-INSTALLATION STEPS
Before the PlacePod is installed there are some prior steps that should be performed.
2.1 GATEWAY INSTALLATION
1. Ensure the LoRa Network Gateways are installed and functional.
2. Perform a site survey to ensure that the RF signal is strong enough. PNI recommends
having an RSSI reading of around -90dBm as a reference when no vehicle is parked
on top of the parking space.
3. Provision the PlacePod onto your PNI Cloud account, or ensure it is provisioned onto
the LoRa Network you intend to use.
2.2 PREPARING THE PARKING SPACE
1. Clear any debris in the park space with a deck broom.
2. Using a tape measure or chalk snap-line, locate the center of the parking space.
3. Mark the center of each space using the chalk snap-line.
Figure 3: Align PlacePod with center of parking space
2.3 PARKING LOT MAP (RECOMMENDED)
1. Each sensor has a unique Serial Number and barcode located on a label on the
bottom of the sensor.
Figure 4: PlacePod Identification Label
2. Before placing the sensor into is hole or bonding to pavement surface, record the
sensors unique Serial Number at its location on the map.

Figure 5: Sample Parking Map with PlacePod Serial Numbers
3. Knowing the location of where each sensor is installed is useful for individual parking
space monitoring as well as trouble-shooting sensor performance and communication.

3 EQUIPMENT NEEDED
3.1 IN-GROUND SPECIFIC EQUIPMENT
•Portable core drill with 4.5-inch diameter drill bit (such as Hilti DD-150-U drill)*
•Water source for lubricating the drill site during drilling (optional)
•Wet/dry vacuum for removing extra debris from the hole area (optional)
•Leveling sand for aligning the sensor in the hole (fine sand such as play sand works well)
•Epoxy Sealant and Applicator
oAt the time of writing PNI recommends: Fabick Pour-Pac MP-55 polyurethane epoxy,
which can be ordered directly from the manufacturer:
ohttps://www.fabick.com/sealants.html
oApproximately 3 sensors per 2-part kit using minimum application.
3.2 SURFACE MOUNT SPECIFIC EQUIPMENT
•Coarse Sand-Paper
•Adhesive and Applicator
oAt the time of writing PNI recommends: Superior Industries #303 Bumper Mount,
which can be ordered directly from the manufacturer:
ohttps://www.superior-industries.com/_303_bumper_mount_product_278.html
oApproximately 6 sensors per 2-part kit using minimum application.
•Concrete Sealer Stripper
•Hammer Drill with Mason Bit
•¼” Self-Tapping Masonry Screws
oAt the time of writing PNI recommends: Wedge-Bolt ¼” X 1 ¾” manufactured by
Powers Fastening Innovations. Two versions are available:
oPart No 7701N - 410 Stainless steel @ $1.44 each (low magnetic)
oPart No - Zinc plated carbon steel @ $0.24 each
*PNI strongly recommends that drilling be done by a professional concrete and pavement
drilling company, to ensure that proper safety procedures are followed.

4 INSTALLATION ON GRADED SURFACES
IMPORTANT
PLEASE FOLLOW THE INSTRUCTIONS FOR THE MULTIPART APPLICATION OF THE SPECIFIED
EPOXY FILL EXACTLY AS DESCRIBED DURING INSTALLATION. THE APPLICATION PROCESS IS
DESIGNED TO ALLOW THE EPOXY TO FULLY ENCAPSULATE THE PLACEPOD ON THE TOP,
BOTTOM AND SIDES IN ORDER TO PROVIDE LONG TERM PROTECTION FROM MOISTURE,
CHEMICAL AND OTHER FORMS OF CONTACT DEGRADATION OVER THE INTENDED LIFETIME
OF THE PRODUCT. IMPROPER INSTALLATION MAY RESULT IN SHORTENED PRODUCT
LIFETIME.
1. Pavement angle must be taken into account when drilling the core. The depths specified
in the following pages are based on a level surface. Depth measurements must be made
from the lowest point on the graded surface as shown in the illustration below,
particularly if the core drill rig places the core-bit perpendicular to the pavement surface.
2. When back-filling with sand, the sand needs to be as level as possible. This will allow
for even layers of epoxy to be applied. The epoxy is self-leveling, therefore the bottom
layer of epoxy will enable the sensor itself to be level once inserted into the hole.

5 IN-GROUND INSTALLATION PROCEDURE
This section outlines the steps required to physically install an in-ground PlacePod.
5.1 PREPARING THE PARKING SPACE
See Section 2.2.
5.2 DRILL THE CORE
Have a professional drilling and coring company drill the holes for each sensor. Give them
these instructions for drilling:
1. Drill a 4.5-inch diameter hole. Do not use a drill larger than 4.5 inches in diameter.
2. Drill to a minimum depth of 1.5 inches. Drilling completely through to the bedding layer
and back-filling with sand to the 1.5 inch depth is preferred. Note: If you do not drill
through to the bedding layer, you will need an extra step to remove the core. This
usually involves an impact device such as a jack-hammer or air-chisel.
3. Optional: Flush the drilling surface with water to lubricate the drill and dampen dust.
Figure 6: Drill the hole for the PlacePod
5.3 REMOVE THE CORE
Remove the core after drilling is done.
1. If drilling down to the bedding layer, the core may remain in the drill bit when it is
withdrawn from the hole. Remove the core from the drill bit by tapping the side of the drill
bit with a non-marring material.
2. If drilling partially into the pavement without penetrating the bedding layer, the core will
have to be broken out using an impact device such as a jack-hammer or air-chisel.
Figure 7: Remove the core from the hole

5.4 PREPARE THE HOLE FOR THE PLACEPOD
After the core is removed, the hole needs to be cleaned out and leveled so the PlacePod
sensor can be placed at the right height.
1. Remove leftover debris to make a relatively flat surface.
2. Backfill with sand to a depth of 1 3/4 inches if necessary.
WARNING!Make sure that the hole is completely dry before proceeding. If the uncured epoxy
comes into contact with moisture, it will foam adversely affecting epoxy performance and
adhesion.
3. Add epoxy to level the surface to 1.5 inches depth from pavement surface Allow epoxy
to harden.
Figure 9: Bottom Layer of epoxy
5.5 INSERT THE PLACEPOD INTO THE HOLE
1. If mapping of the sensor location is being performed, record the sensor Serial Number.
2. Add a second layer of epoxy approx. 1/4 inch thick.
3. Insert the sensor into the hole so that it is seated onto the bottom of the hole, forcing the
uncured epoxy up around the sides of the lower housing.
4. The ideal placement is to have the top of the sensor sit 1/4 to 3/8 of an inch below the
surface of the asphalt.
Figure 10: Sit the PlacePod in the hole (ensure top of sensor is 0.25in from surface)

PNI Sensor
DOC# : PlacePod Installation Guide R01_draft7 Page 9 of 14
Note: To optimize signal strength orient the sensor in the middle of the space such that the
arrow (inside the half circle next to the “P”) points towards the nearest gateway.
5. Place a weight on top of the sensor to prevent it from floating in the epoxy during curing.
5.6 SEAL THE HOLE
1. Once the epoxy from the previous step has cured, remove the weight and fill the
remainder of the hole with the epoxy until it is flush with the pavement surface. To
reduce formation of bubbles, fill in any gaps between the sensor and the wall of the hole
before covering the top of the sensor.
2. Make sure the epoxy completely covers the top of the sensor and is flush or slightly
below flush with the pavement surface.
WARNING!The epoxy must not protrude above the pavement surface in order prevent vehicle
weight from being transferred directly onto the sensor.
