Cat proximity sensing with microchip implants?
I know that pets can have microchips implanted under their skin for
identification purposes. Does anyone here know whether these chips can be used with a proximity sensor? I would really like to create a cat door that would allow my cats--and only my cats--to enter. . .even if they lose their collars with the magic magnets on them. It could also be useful for an automated feeding system, since one of my cats has a weight problem and tends to eat all of the food that I leave out. Thanks -Mark |

I don't think that those pet tags have enough range to be useful. You could always ask your vet what the range is. It's likely to be quite expensive anyway. I think that cows have ID tags that only allow them into their own stall for milking, although I could be wrong. |

The ID chip needs a strong magnetic induction field to get it to respond, and then the signal is very weak, it may be possible to design something, but I think it would drain a lot of power. -- Bob. The facts expressed here belong to everybody, the opinions to me. The distinction is yours to draw... |
