ir has to be basically "line of site" to work, and rf would work better. just search the forums for "fm transmitter", last i saw, audioguru had a good one, apparently with good range and quality.

As i told earlier i m juist a beginner and don't know from where to start.Yet i don't want you people to tell me everything and i do nothing except to copy your circuit diagram to PCB and present it to my teacher.
I just want to know from where to start.which term or statement will give me my required thing if i google it.
I have searched for the fm transmitter in the forum and found what you wanted to see me.
But the problem is that i want to know both about transmitter and reciever (or sensor) and it is just a transmitter.
will the led be plugged in to an external power source, then you just want to turn it on remotely. or is the led going to be "powered" wirelessly? what kind of range do you want, is it going to be line of sight or around corners and stuff?
