Pet sensor Answered

I'm trying to find a device or find out how to make a device that would alarm me when one pet in particular is passing through the doorway.  Any suggestions?

It if called RF ID tag.
Put one on the collar and a receiver on the door.
What you use to read the data out and use it is up to you.

I am so excited that you replied. I'm afraid I know very little about electronics. Where would I buy a RD ID tag? And what is a receiver for it?

And as far as data, I think I was just wanting something to make a noise.

Can you spoon feed me more info?
