The special feature of parking sensor which makes it a boon for parking maneuver is the use of the ultrasonic proximity detectors fitted in the front and/or rear bumpers which helps in measuring the distances to nearby objects at low level. Parking sensor measures the time taken for each sound pulse to be reflected back to the sensor.
Parking sensor at the rear gets activated when reverse gear is selected and automatically gets deactivated when any other gear or neutral is selected. In the same way, parking sensor at the Front gets activated by pressing a button and then automatically gets deactivated as soon as the vehicle exceeds certain speed; this generally finds its use in avoiding unnecessary warnings in slow moving traffic.
In a car that is fitted with a parking sensor, the most common form of feedback given to the driver is through audible beeps or tones. The frequency of the beep is an indication of the distance from an obstruction. The more is the frequency of the beeps; the closer is the vehicle moving to an object. Where a continuous tone is heard, it indicates the vehicle is extremely close, signaling a warning to the driver to stop immediately in order to avoid collision. Some parking sensor also makes use of visual aids such as LED or LCD readouts to indicate distance from an object.
Parking Sensor relies on the functioning of the reflection of sound waves, so its shortcomings includes that it may not be able to detect some items which are generally not large enough to reflect sound indicating an insecure detection of obstruction. For example, a narrow pole or a longitudinal object may not be able to reflect sound.
