I need a list(data numbers) of short range IR emitter and detector(not very expensive) which can be used as a break beam sensor.. I also like to know what is the specific IC number which is used to tune the IR emitter's frequency which matches with the detectors receiving frequency. I have heard that the frequency is something like 38KHz.. If you guys can also give me a link to the circuit diagrams which I have to use for this, it will be a great help... :-)
