For the best info on simple IR sensors, I would take a look at Parallax's BOEbot tutorials.  You can download it for free here:  http://www.parallax.com/dl/docs/books/edu/Roboticsv2_2.pdf

Start reading Chapter 7 begining on page 235

Why not just buy a Sharp IR rangefinder (http://www.societyofrobots.com/sensors_sharpirrange.shtml)? They cost like $12 :P
