Wireless outdoor parking sensors

1. Intelligent Parking is a revolutionary product created by Intelligent
Devices, Inc. that simplifies the way parking works. Intelligent Parking
assists your customers by giving them the correct information when trying
to find a parking spot. Through the use of parking sensors and display
boards the motorist can easily navigate the parking level to an open bay.
The wireless parking sensors are a new addition to the Intelligent Parking
System. These sensors operate off battery power and can be easily
installed. The wireless sensors are optimal for parking facilities that are
open surfaces. This includes parking garage roofs and outdoor lots. With
the wireless sensors, each bay is monitored allowing the parking facility to
maximize capacity.

2. System Design:
A Wireless Sensor is to be installed in each parking bay to determine if the bay is occupied. The Wireless
Sensor does this by measuring very small fluctuations in the earth’s magnetic field caused by large iron or
steel objects, such as cars. The sensor wakes up every 15 seconds to measure this field. If the measurement
has changed to a stable level, a message is transmitted through the Router Box to the Zone Controller. Even if
no change is detected, the sensor will transmit the data to the Zone Controller every two minutes, to ensure the
controller that it is still operating properly.
