I have one sharp sensor and I have to use it to measure the height of a block (6cm - 12 cm). How can I accomplish this ? Actually it is to be connected to a robot which will move near the box and determine its height.

If possible please suggest a solution that doesn't require moving the sensor. But any method will do fine.
