> Question about using IR Detector for measuring distance

Regardless of the directionality problems you are having, you are probably
going to have an EXTREMELY hard time measuring distance using the module you
are experimenting with. How do you intend to measure distance once you get
the directionality problem sorted out?

Sound (ultrasonics) is useful because the trip times involved are in the
millisecond range. Using light the times are in the nanosecond range. There
are other method using eg phase measurement. None of these are suited to the
use of an IR detector module.
