I would like to start a sensor remotely. It's a sharp IR sensor and the remote will be about 4 feet from the sensor.

Thanks,Leo

Leo, what do you mean by "starting a sensor" ?

[leo357leo]

redwire, I do not want the IR to be sensing until I remotely start it to sense. Also I will not be directly facing the IR when I remotely start it. Any ideas?


Thanks,Leo

Can you give an example of what you want to do please. I am a bit confused by your description.

You can fetch readings with an Xbee... or do something like this: http://community.livejournal.com/arduin ... /2417.html

Any ideas?

Use a TV remote and an IR remote received chip a decoder and a transistor switch.

Actually what I want to start is an arduino program remotely. This is the job: I am going ot be standing in an athletic position with the IR sensor behind me. I want to then start the arduino program and a buzzer to go off if in my athletic move I move more than 5 cm from the IR sensor. If the buzzer goes off it will end the loop in the program. Then within a few seconds I'm going to get into the athletic position again and restart the program.

I hope this clears things up, any ideas.

Ir sensor -> xbee/nordic/whatever (or any other wireless) sent as a raw signal
uController receieves signal and does it's thing.

I dont know what xbee/nordic/whatever means, is this a progrmming line or a suggestion on what to do. Sorry for my ignorance.

Leo,
As is often said in such fora as this, "Google is your friend":

In this case, though, searching the SparkFun site should suffice:

THANKS FOR YOUR HELP

Eric, I;m a little cofused on physically what to do with these remote modules. Do I put this chip in the arduino then have a hand held device to communicate with it?

Thanks,Leo
