code outputs velocity while there is no movement
hi the code outputs a measured speed of around 2.5km/h while there is no movement around it. I suppose since this is a doppler radar, the code should output 0km/h when there is no movement.
The code simply counts the frequency output from the device, so I would blame the device. You could try lowering the sensitivity as per the example sketch to see if that makes any difference.

by lowering the sensitivity do you mean the line of code which defines sensitivity or the potentiometer on the back?
The line of code

well I tried changing it...didn't make any difference what was your output?? did you get 0km/h?
