Parking Sensors, Car Accessories Small But Important

How important is parking sensors on the car? Do you have an interesting experience when parked? If your car is equipped with parking sensors?

Parking sensors specifically designed to alert the driver when the car park will be the object on the back of the car. Parking sensors are accessories that have become an innate component of a car. Parking sensors meberi convenience for people who are not very good driving the car.

There are several types of parking sensors used in cars, such as:

1. The parking sensor with a beeper. Parking sensors usually have a beep from the speaker buzer manifold. This kind of parking sensor is a component that is widely used in cars.

2. The parking sensor beeps and display combinations. Parking sensors provide instructions distance to an obstacle behind the car.

3. parking sensors with the human voice. This sensor replaces beep to sound human gesture. Left for example, one meter. Parking sensor is equipped with a numeric display distance instructions are digital.

4. The parking sensor with camera. Parking sensors will help the driver to know the existence of an object behind the car. This sensor is equipped with CCD or CMOS camera. Parking sensors of this type is the type that is most flattering.

the factors that most affect the performance of the parking sensor is sensitivity. Sensitivity determines how well the sensor works. Do not let the parking sensors provide an alert when a car has crashed into objects behind it.

These sensors detect objects ranging distance of 1.5 meters. Examples on a car, the buzzer will sound with a pause of 225 milliseconds. At a distance of 1 meter reads faster with pause 75 milliseconds and at a distance of 0.5 meters will sound without a break. This indicates sensitivity parking sensor device works well. There is a maximum speed that the sensor works, corner sensor will be active below 10 km / h, so try when parking the vehicle in a position to run backwards do not exceed the speed that can reach the parking sensor.

Sensitivity indeed depend on several factors. Such as the width and angle sensors, the number and spacing of the soil. Width and angle of the sonar greater, will make the sensor more sensitive. In addition, the position sensor height from the ground, also affect sensitivity.

Distance or height from ground sensors also have an effect, sometimes if the ground clearance of the car is too high, it would make more degree angle away from the object that is lower than the position of a car bumper.

Ideally for the installation of parking sensors, sensor height from ground level between 50-70 cm. With the distance of the outer side of the car to the first sensor 9-15 cm. While the gap between the first and second sensors, can be calculated by the formulation of 0.3 W (width of the car). For example, if a car width of 100 cm, then the distance between each sensor is 30 cm (0.3 x 100 cm).
