Advantages of Ultrasonic sensor | Disadvantages of Ultrasonic sensor
This page covers advantages and disadvantages of Ultrasonic sensor. It mentions Ultrasonic sensor advantages and Ultrasonic sensor disadvantages.
Definition of Ultrasonic sensor:
The sensor which uses ultrasonic sound waves for sensing is known as ultrasonic sensor.
Ultrasonic refers to unaudible sound waves above frequency of 20KHz.
There are two parts in an ultrasonic sensor viz. transmitter and receiver.
The transmitter transmits the ultrasonic waves towards the object to be detected.
The receiver receives the echo from the target and determines its distance.
Hence it is known as distance sensor. There are many applications of ultrasonic sensor such as
doors, level control, anti-collision, web brake etc.

information.
Advantages of Ultrasonic sensor
Following are the advantages of Ultrasonic sensor:
➨It has sensing capability to sense all the material types.
➨This sensor is not affected due to atmospheric dust, rain, snow etc.
➨It can work in any adverse conditions.
➨It has higher sensing distance (in centimeters and inches) compare to inductive/capacitive
proximity sensor types.
➨It provides good readings in sensing large sized objects with hard surfaces.
Disadvantages of Ultrasonic sensor
Following are the disadvantages of Ultrasonic sensor:
➨It is very sensitive to variation in the temperature.
➨It has more difficulties in reading reflections from soft,
curved, thin and small objects.
