Upload the below code to the Nano board using Arduino IDE. Now we enter our auth code and Wi-Fi credentials. The first row shows the distance, and the second.
The basic code is taken from the arduino cc forum and I just added an LCD display for a visual representation of the results. If we make the measurements in a time period of 1 second, then we get the speed of movement of the object in cm/s. Then we define Echo & Trig pins of Ultrasonic sensor to D1 & D2. distance2 - distance1 distance speed at a given time.
