Need help setting up my ultrasonic distance sensor

[Megahertz]

Hi,

Everything works as written ...

W1 = 500 is a distance of 1 meter ...

...

try 2500 instead ...

and note no measure will send back ... 5000 Pulsin units ( 50 000 µs )

Hi, it works fine with 2500. Can you please explain how you calculated 2500? Thanks
