Hello people, having trouble parking ? No problem, here's a good solution for you, get parking sensors fitted to your car.
A sensor is placed on the rear bumper of the car, which is capable of both emitting and detecting ultrasound. As it pulses, a computer measures the time it takes for the sound it emits to be heard again. Parking sensors operate at a close range and some sensors have a minimum operating range. When the user set distance threshold is passed, the sensor will emit an audible sound alerting the driver that it is getting close to an object.
These sensors work on ultrasound theory. The ultrasound sensor is based on echo-location (like SONAR, the same thing bats use to navigate). The pitch, or frequency, of the sound is so high that humans cannot detect it, which is useful because it provides accuracy.
The ultrasonic parking sensor is considered the cheapest form of a parking sensor, thus it comes with several problems which other technologies address. The first is that it can miss small objects or objects which lay below the sensor's cone-shaped operating range and sometimes requires multiple sensors to be attached to the bumper to get full coverage on both sides of the car.
Now a days, the reverse parking sensor systems are accompanied with a view camera, that let's you 'see' the reverse view on a screen fitted in the car's dashboard.
Many car manufacturers are offering this as a standard feature on current models.
Now, who said parking a car is difficult anymore ?
