Ultraljudetäisyysmittaimet
Ultraljudetäisyysmittaimet, often referred to as ultrasonic rangefinders or distance sensors, are devices that measure the distance to an object using sound waves. They work by emitting a high-frequency sound pulse and then measuring the time it takes for the echo to return after bouncing off the object. This time-of-flight measurement is then converted into a distance based on the speed of sound in the surrounding medium, typically air.
The core components of an ultrasonic rangefinder include a transmitter, which generates the sound pulse, and
Ultrasonic rangefinders are non-contact sensors, meaning they do not need to physically touch the object they
