When an electrical signal is added to the transducer to produce sound waves, it vibrates across a specific spectrum. These sound waves fly, and if there are some obstacles, these sound waves will reflect the transducer's echo knowledge. The Echo is converted to an electrical pulse at the end of the transducer. The interval between the transmission of sound waves and the reception of an echo signal is determined here by the transducer. At 40 kHz, the Ultrasonic transducer emits an ultrasonic pulse through the air. These transducers are safer than infrared transducers because dust, black materials, etc. are not affected by these Ultrasonic transducer transducers. The Ultrasonic transducer is excellent at suppressing noise distortion.
