Advantages and Disadvantages of Ultrasonic Sensor Ultrasonic sensors are used in many applications. One of their most common applications is in robotics. That is because they are easy to interface and comprehend. Ultrasonic sensors contain ultrasonic transducers. A transducer can convert one energy form to another. The transducer is the reason why a sensor can emit a sonic pulse. An echo is then created once the emitted pulse reflects off an entity. The original sonic pulse and the echo determine how far the entity is from the sensor. The value of the distance is based on the amount of time that the pulse has travelled from the sensor and back. Types of Ultrasonic Transducers Used in Ultrasonic Sensors The two transducer types that are usually used in ultrasonic sensors are piezoelectric transducer and electrostatic transducer. These two have many differences. 1. Piezoelectric Transducers
