The oIRRange just uses an oA2DX object and does a little scaling. The
scale is useless for your sensor so just use the oA2D directly. You
can consider the more complex oA2DX object but, personally, I wouldn't
bother. We don't always want the absolute distance, we just want to
know if there is something closer than some value.

Or, go ahead and use oIRRange and just rescale the Distance property.
Maybe the .Adjust property can help with rescaling. It is described
in the oA2DX object reference.
