DESI1066 RFID cat flap - YouTube
If your pet is not microchipped, the SureFlap RFID Collar Tag is available as an alternative*. SureFlap collar tags contain a code that is unique to your pet so that if other pets in the neighbourhood have a SureFlap collar tag, or any other type of collar tag used in selective pet doors, they will not be able to gain access. *The collar tag is not compatible with SureFlap Microchip Cat Flaps with a serial number of 1152201 or lower.
RFID cat flaps are one of those projects we see all of the time. They are generally pretty simple to rig up, not too expensive, and have a good “wow” factor for any non-technical friends or family, not to mention tremendously useful. Why did we decide to share ? Well, for one, it is simple. It doesn’t tweet, email, or text message, it just gets the job done. Two, it is excellently documented, including a detailed parts list and a step by step schematic just about anyone could use to build their own. [landmanr] does mention that he recommends some sort of project enclosure to protect the electronics from damage, which would be bad for the poor cat stuck outside.
These reasons and more are exactly whey the microchip cat flap and electronic dog door were invented. These electronic doors go by several other names as well. Perhaps you have heard them called automatic dog doors, magnetic cat flaps, electronic pet door, power pet door, RFID dog door and more. Whatever you decide to call it, they all have the same concept, which is to let you pet in and out of your house automatically.This will also work with collar mounted RFID tags. This means no collar. It will also work for smaller dogs with shoulders less than 6.5” wide and 20 ¼” wide. The Sureflap Microchip Cat Flap is a fantastic choice if for cat and small dog owners.First up on my list for best electronic pet door is the Sureflap Microchip Pet Door. This Sureflap Pet Door was first introduced to the U.K. and did so well it made its way to the U.S. This model is a personal favorite of mine as a cat owner as it uses the veterinarian inserted microchip that contains an RFID chip that automatically opens the electronic pet door.This is a cat door/flap that can only be opened by the animal that wears the appropriate RFID tag. Arduino controls the process. It features a custom made ...Next up on my list is the Cat Mate Elite Cat Flap. This model works a little differently than the SureFlap model, as it does not have the ability to work with RFID microchips. It only works with collar mounted I.D. tags.They solved the issue of getting the antenna nearer the implant location by extending it out from the flap and extending the flap the other way to create a 3-4" tunnel, with the loop at the extreme outside end I assume. They also offer a RFID collar tag, in case your pet's tag won't read or doesn't have one.I am relatively inexperienced with pi physical computing, so for catmon v2 I'd like to learn about RFID readers. My two cats were recently chipped so I have some ready-made volunteers :-). I'm thinking that if I was able to connect an RFID reader to the pi - with an external aerial positioned around the cat flap (say) - then I'd be able to identify the cat and then (with a few tweaks) determine which cat is in and which cat is out.Hi! I'm trying to build the cat flap. I have almost everything finished, except for one step: I tried to make an equivalent antenna, as described, by wrapping 30 gauge magnetic wire around a 26x17 cm PVC box (I need 26.5 loops). I even bought an LC meter, to make sure the inductance is the same. The antenna that came with the RFID module is 477uH, and the one I made around 472uH (It seems somewhat dependent on where and how exactly the exit wires go), but I get nice strings from the original antenna, and nothing from the one I made. I checked the resistance, and it is almost the same - 6 ohm (original) vs 8 ohm (mine).
