What does ultrasonic sensor detect?
An ultrasonic sensor is an instrument that measures the distance to an object using ultrasonic sound waves. An ultrasonic sensor uses a transducer to send and receive ultrasonic pulses that relay back information about an object's proximity.
What is ultrasonic signal?
Understanding Ultrasonics Ultrasonic Sensing/Control Basics Ultrasonic signals are like audible sound waves, except the frequencies are much higher. Our ultrasonic transducers have piezoelectric crystals which resonate to a desired frequency and convert electric energy into acoustic energy and vice versa.
How much distance can ultrasonic sensor detect?
They DO NOT locate objects moving about in a 3-dimensional space. They DO NOT measure farther than about 70 feet (21 meters). They DO NOT measure at very high repetition rates. Due to speed of sound limitations the fastest rate is 200 Hz at a max distance of about 24 inches.
