When I made the suggestion about striking the box and measuring the frequency of the sound it makes, I was thinking along the lines of the difference in sound when you strike a glass that is empty compared to the sound when the glass has some water in it. The pitch (frequency) of the sound increases with the height of the water in the glass. I think Peter was alluding to the same thing.
If the method works at all, it will work best with an elastic container, a quality not embodied in a cardboard carton. I have no idea if the difference in sound between a carton filled with 49 packages and one filled with 50 packages would be detectable by any available sensor.
