7 Important Things to Know About Ultrasonic Sensor
Ultrasonic sensors have evolved drastically in the past few years. Today, these devices are used in a range of applications like measuring the distance between two objects. The sensor works with the help of ultrasonic sound waves. The sound waves are carefully converted into electrical energy. When compared to audible sound waves, UV waves tend to travel at a faster pace. This means human ears are not capable of hearing these sounds. An ultrasonic sensor has two important components, the receiver and the transmitter. The transmitter controls the amount of sound that is emitted by the piezoelectric crystals. While, the receiver encounters the sound which is transmitted towards the target. To compute the distance between the source and target object, the time required for the sound to reach is utilized. The total time required is nothing but two times the distance, divided by the speed of sound (343 meters/second). Now, here are a few interesting facts about the ultrasonic sensor. 1.
