Installation Instructions

FEATURES
• Sensor is wirelessly paired with an IPS parking meter to detect the presence or absence of a
vehicle
• Sensors are 3” in diameter and 3” in height and
• Sensor is fully encapsulated from the elements and contains its own battery power source of
two lithium ion high capacity 3.6VDC cells. The open wire loop antenna is a ¼ wavelength and
correctly characterized for very low reflected power loss for a completely wireless solution
• IPS utilizes an air/water tight sensor housing, which allows sensor to be easily removed should
service in the field be required.
SENSING METHODOLOGY
IPS Vehicle Detection Sensors use multiple sensing elements to produce maximum sensor
sensitivity. A ferrous object, such as a vehicle’s engine block, alters the local magnetic field
surrounding the sensor. As a car pulls into a parking space, the sensor detects the change in
the magnetic field and relays the information to the IPS parking meter. The sensor can also be
fine tune to register a movement of a vehicle in a specific space increasing accuracy and making
data received more valuable.
INSTALLATION
For best performance, sensors are installed below-grade, typically 2 – 3 inches below the
surface with the loop antenna and optics above grade or street level to be able to detect
vehicles.
For the most accurate results, sensors are installed in the ground under the area where the
transmission and engine of the car is expected to be.
BENEFITS
• Sensor communicates directly to IPS meter rather than a mesh communication network,
providing the most reliable communication transmission available at a significantly lower cost
