    Use Opto reflective sensors. which have led and photo transistor in single package. U can try for RPR 220 which should cost around Rs.70.

    Yes, I do agree with you. I've an IR pair but don't have it's datasheet. Both looks same but one has longer leads. How to distinguish them for TX and RX? Is there any application circuit for this?
    Never give up!
