Infrared Receiver

Here is a nice tutorial Bruce made available on his website

You would need to pick a IR transmitter. They emit very different signals. (the TSOP1236 IR will receive and decode all of them). Sony, sharp or philips ... each transmits IR differently.

Best to use a 38kHz receiver rather than 36kHz if you are planning on decoding various protocols.

Philips (RC5 RC6 RCMM) tend to be 36kHz and uses Manchester Encoding

NEC tend to be 38kHz and uses space encoding

Sony tend to be 40kHz and uses pulse encoding

Sensitivity of the receiver drops off outside its designated centre frequency so 38k works best as a generic receiver. eg TSOP1238, TSOP1838, TSOP4838 etc

[dhouston]

TSOP1100 handles 33-57kHz carriers.

TSOP1100 handles 33-57kHz carriers.

Thats useful to know.

Thanks Dave

THANK GOD FOR GOOGLE!

Or lots of us would sure be in the dark , Could I be the only one out here who didn't know what a TSOPxxxx was?

Thanks a lot guys, but for now, i will NOT focus myself on the programming. Maybe later. What I would like to know is basically the detailed & simple technical functionality on how an infrared receiver works (layman explanation).

thanks a lot everett, that was an excellent reference. I will study the explanations and make it as a reference.
