    hi!!

    i have been new to the world of sensors!!

    i have been using the til 38(emitter) and til 81(detector) pair but the range of this has been very low!!
    til 81 is a 2-pin photodiode! the range i have been getting is around 8 cms!! can anybody suggest anything for increasing their range!!
    or if anybody could suggest any other gud range sensors.....
    i need a range of around 70-80 cms..
    plzzz help.
