IN our parking guidance system, every parking ***ce is monitored by a single ***ce sensor. The sensor is
Installed on the ceiling in the middle of each parking ***ce. The sensor ***ects the occupancy status through ultrasonic
Distance measurement. The measured distance value is transmitted to the connected zone controller and
Co***red to the previously stored ceiling height value. If a vehicle is occupying the parking ***ce, the values do not
Match therefore the zone controller transmits to the sensor which changes the indicator LED light
From green to red. . The zone controller up to 64 single ***ce sensors can be
Connected to one controller.
