Ultrasonic range finders Application :
Ultrasonic range finders measure distance by emitting a pulse of ultrasonic sound that travels through the air until it hits an object. When that pulse of sound hits an object, it’s reflected off the object and travels back to the ultrasonic range finder.The ultrasonic range finder measures how long it takes the sound pulse to travel in its round trip journey from the sensor and back. It then sends a signal to the Arduino with information about how long it took for the sonic pulse to travel.
Ultrasonic range finders are fun little sensors that can measure distance. You can use them to find the distance to an object, or to detect when something is near the sensor like a motion detector. They’re ideal for projects involving navigation, object avoidance, and home security. Because they use sound to measure distance, they work just as well in the dark as they do in the light. which can measure distances from 2 cm up to 400 cm with an accuracy of ±3 mm.

What Goes into the Making of a Transducer?
The main component of a depth transducer is the piezoceramic element. It is the part that converts electrical pulses into sound waves, and when the echoes return, the piezoceramic element converts the sound waves back into electrical energy. Piezoceramic elements are most often in a disk form,but they may also be in the shape of a bar or a ring. A transducer may contain one element or a series of elements linked together called an array. A transducer is made up of six separate components.
