Few years ago ,i have heard some information about
pilotless automobile ,im always puzzled by this high technology ,how they can

backup parking sensor’s invention is largely depend on the beautiful world
we lived in .its use the theory of supersonic ,when we say the topic about
supersonic ,its have a long history ,we all have benefits from it ,The
ultrasonic sound waves with frequencies higher than 20000 Hz, it is a good
direction, strong penetrating ability, easy access to more focused sound
energy, in the water, far transmission distance, can be used for distance,
velocity, cleaning, welding, gravel, sterilization. There are many applications
in medical, military, industry, agriculture. Ultrasonic wave is so named
because its lower frequency limit is approximately equal to the upper limit of
human hearing .
Car backup parking sensor is a device can warming
people have a special care to those obstacles people can not see .car backup
parking have two kinds ,one is electromagnetic parking sensor ,the other one is supersonic backup
parking sensor .Electromagnetic parking sensor relies on a vehicle moving
slowly, steadily toward the object. When the obstacle is detected, the vehicle
temporarily stops, the sensor will get the signal the presence of an obstacle.

your beloved car ,4 Parking Sensors Car Reverse Backup Front Rear LCD Display
System Radar Alarm is a good
choice ,its can detect small children and low walls as well and help to prevent
