Hi everyone

My proposal project is Library System with RFID :

simple .. just go to the PC search for specific book by it's name or ...

then RFID signal send to all the books ( each book has passive tag )

the book's tag that match with this signal will reply..

Now...I wanna put for each shelf a small board contain LED circuit ...

so the shelf with that chosen book ...will light on ...

main point... how to make LED circuit works By RFID ??

Any solution ..suggestion..

Thanks

 

Books & RFID exp. goes back to '70's & early '80's & was based on a system wide tagging, ie, all books had the same tag, Range was around 10 ft. Hope things have changed for your program.

RFID is not a location finding system, so the book will have to be in the correct location for the LED on the shelf to light up. If the book has to be in the right location anyhow, why not just put the location information in the PC database (like every library system already does) and eliminate the RFID?

 

agree with you brother..but what if the book wasn't there ( someone read it at that moment ) ...the LED will not light up..

many modern library now depend on RFID system instead of barcode ...

also RFID system has other functions than finding books..

one of them for find out the location..

So please any suggestion or hint about the circuit that help ...
