The speed of ultrasonic waves in air is equal to the speed of sound which is 340 m/s (meter per second). High-frequency sound waves reflect from boundaries to produce distinct echo patterns. Here v is the speed of ultrasonic waves in air. But, if you want the distance in centimeter units, multiply 340 with 100. . When sound waves are transmitted in the environment then waves return back to the origin as ECHO after striking on the obstacle. Scanning range of ultrasonic sensors In general on ultrasonic sensors, the less sound the object being measured absorbs, the greater the possible scanning range. If not what would be the solution? Distance is used to control servo motor. The ultrasonic distance sensor has 4 Pins: Vcc, GND, Trigger and Echo. While laser distance meters use a modulated, closely focused and visible laser beam for measurement, ultrasonic distance meters emit high-frequency tone pulses. The operating range specifies the distance up to which measurement on common objects with sufficient operating . This is similar to how radar measures the time it takes a radio wave to return after hitting an object For converting this into the distance here the formula Find answers to the most commonly asked questions about ultrasonic sensors including their range, how they work, and more.
