Distance measurement of an object in the path of a person, equipment, or a vehicle, stationary or moving is used in a large number of applications such as robotic movement control, vehicle control, blind man's walking stick, medical applications, etc. Measurement using ultrasonic sensors is ...
This Grove - ultrasonic sensor is a non-contact distance measurement module which works at 42KHz, suitable for projects that require middle distance measurement.Usage:Clone this repo or download as a zip;Unzip the zip file if you downloaded a zip file;...
//We have to be careful here. If we request a measurement before the measurement has been taken your //code will be blocked until the measurement is complete. In order to stop this from happening we //must ensure that time between measurement requests is greater than the timing budget and...
Arduino Distance Sensor Code There are a few different code implementations that you can use to calculate the distance. This calculation is always done by using the signal that is being produced by your distance sensor. The easiest method is to use a library, but for this tutorial, we will ...

in water than they do in air, sonar is preferred over other types of sensors like radar for this reason. Even though it's preferred for underwater sensing, sonar can still be used in air; however, there exists the small chance of interference, which we might see when measuring distance....
