I dont know much about RFID technology. I understand like what it does but not how to use it so i figure the best way to teach myself is to start using it. I want some sort of reader that is not to expensive. i want it to be in my car and with the help of one or two antennas i want it to be able to read the tag from about 5 feet or so from the car. Any help?
i know i need a micro controller. I didnt think it was magic. but with that reader that you showed a picture of, can i hook it to a micro controller just for presence detection or what?
A rotating radar dish, Think warship, or aircraft carrier.
You can do a simple Ultrasonic obstacle finder circuit that would "ping" if anything was in range. Awesome.. Could you imagine driving down the street with that on your roof?
Its just that those parallax readers, i've watched a few videos and stuff and everyone has it hooked to the computer. i dont want that. I want a separate thing.
That device is a separate thing, it's probably the easiest method to get what you want but only very short range. You can connect it to a PICAxe if you want, it's just serial data.
Ok that sounds good. I didnt know how it transmitted its data but that should work. And how do they have long range RFID readers? i assume passive tags help increase the range as well as antennas and such
