One straightforward way is to use the library to modulate an ir led at 38khz and use a standard ir detector module to detect the signal.
Long range ir beam break detector circuit.
In this mode the beam is normally detected by the receiver and is interrupted by an object that passes in front of it.
I m using your circuit as my project for my final year project.

When you need a longer range you can add extra ir leds.
The answer was too long for the comments section so i ve extended into a blog post.
Long range 10mt ir beam break detector.
The range of the long distance ir beam break detector easily reached 7 meter using a single ir led driven with about 10 ma which is well below the maximum current.
