    guys i am very much confused about ir sensor circuit...
    can you please tell me the both circuits using ir transmitter and receiver( 2 pins), and the second with ir transmitter and sensor( 3 pin sensor, i don't know the configuration of these 3 pins).
    actually i want to use this sensor output with 89c52 micro controller and gonna make a line tracker... please tell me the schematics of circuit which give 5 v on the track and 0 v off the track.Obviously using voltage comparator.which one will be most suitable comparator tell me ic number thanks

    Look up "sharp IR sensor module" and you'll find a whole bunch of options. Take a look at the datasheets and you'll learn how these things are wired and how they work. Most are very similar, so what you learn about one applies to many.
