Ultrasonic sensors work by generating high frequency sound waves and evaluating the echo received back by the sensor to calculate the time interval between sending and receiving the signal to determine the distance to an object. They use ultrasonic transducers to convert energy into ultrasound waves above the range of human hearing. Ultrasonic sensors are used in applications like submarine radar to detect surroundings, parking sensors to assist with parking by detecting obstacles, and level sensing in industry to monitor levels like in water treatment centers.

2.  Ultrasonic sensors (also known
as transceivers when they both send
and receive) work on a principle similar
to radar or sonar which evaluate
attributes of a target by interpreting the
echoes from radio or sound waves
respectively.
 An ultrasonic transducer is a device that
converts energy into ultrasound, or
sound waves above the normal range of
human hearing.

3.  Ultrasonic sensors generate
high frequency sound waves
and evaluate the echo which is
received back by the sensor.
 Sensors calculate the time
interval between sending the
signal and receiving the echo to
determine the distance to an
object.
WORKING
PRINCIPLE

4.  Submarine Radar : The ultrasonic
sensor use in submarine to detect
the surrounding by projectile the
echo to the surrounding and build
an image of what is the view in the
sea.
 Parking sensor : The ultrasonic
sensor use in car to assists the
parking by detecting the distance
between the obstacle behind. The
sensor can be found at the bumper
of the car.
 Level Sensing : In industry,
ultrasonic sensor already been use
widely to detect a level sensing
such as in water treatment center
where it help to monitor the level
of water for treatment.
