PiFace and RFID for Garage Door Opener

If you can link in the actual part number I may be able to provide some help

I have been developing a cat flap using RFID

not much difference between a flap and a garage door (Aside from Size)

Peter

One issue I was considering Peter is that for a Flap you are right up close to the sensor.

However if you are in the car you need to be at least a couple of bonnets away from the door and I assume pickup sensor.

Only way around that is to have some sort of post with the RFID pick up on which you place your rfid fob/card

Yes I agree but Mike was referring to replacing a keypad rather than a remote

and yes It is possible to have a reader down the drive way a bit on a post or wall depending on surrounding architecture, hopefully Mike has considered this or will now at least.

RFID will only work to a few CM normally unless you go to great expense and install one like they have in stores to detect people stealing goods as they walk through the doors (About 4feet high and 2 - 3 feet wide... )

Another option would be to use an RF transmitter maybe NRF24L01 attached to Arduino look alike or custom board to transmit the code, this is actually quite easy and would solve the range issue and still be cheap to implement

Well this is the start of something bigger I hope. I have car openers. What I eventually want to build is a Siri proxy into this setup. I want to build a home automation setup where I can say Siri lock the house - then it makes sure all lights are off garage is closed and doors are locked. This is just the first step.

Well then you may want to either add WIFI or a Bluetooth to the garage door end of the system, making it easy to interface to the phone

I already have a nifty wifi dongle that works quite nicely. It's a leftover from a different project.

Yeah hopefully he'll include that into the design.

BTW the "RFID" that they use as an anti theft device isn't actually an RFID pa se but a diode junction set up to resonate at the frequency of the Field emitted around the doors etc.

Ah, did not know that, we live and learn

Either way though it would still take a very large coil to work over any significant distance making it very prohibitive to build

Back to the original question - does anyone have any pointers or wiring guides for something like this?

Any and all help is appreciated.

Thanks guys/gals.

Ok made some progress here -

Wired the Red (power) to the 5v  connector and the Red/White wires to the first 2 input connectors. I wired the ground (Black) to the farthest right connector and I have lights and sounds.

I need to debug the input on it to see what i sees when I swipe the RF fob against it. Ill do some of that tomorrow.

Thanks

yes those things cos buck loads!

seeing as you are trying to bring the iPhone or such in to  the mix why bother with RFID.

I think that it's  bit of a diversion from the integration idea.
