Question

Hi. I'm trying to attach sensors to my cats. They don't appreciate it as much as I do. What have y'all done to attach sensors to your pets?

Peter The tags use a similar data format, but they are 134KHz rather than 125KHz. Obviously the antenna in the implanted chip is smaller, so therefore its affect on the reader is less, hence why you need a higher Q antenna. (They work by shorting the antenna which then detunes the reader antenna) There is an Australian supplier who can supply the whole reader or the chips, and Robert Accardi is a great guy to converse with. http://www.priority1design.com.au/shopfront/index.php?main_page=product_info&cPath=1&products_id=24 Texas Instruments has these http://www.ti.com/tool/mrd2evm They also have some IC's that are -40 degC and remote antenna options. http://www.ti.com/lsds/ti/wireless_connectivity/nfc_rfid/products.page#p1507=134.2%20kHz&p199=I/O%20Logic OreganRFID have tags, but so does any vet http://www.oregonrfid.com/ I agree the commercial ones can be expensive, but one design had a porch like extension, which may be an idea to keep out the snow. http://intl.petsafe.net/en-gb/support/doors/cat/big-cat-small-dog/petporte-smart-flap-microchip-cat-flap @fvan Looks like this is a very nice feeder. https://www.sureflap.com/en-gb/pet-feeder/microchip-pet-feeder You guys are making me want to resurect my project ...

RFID Keyfob on a collar to activate the cat flap is a project in the works

Hardest thing at the moment is getting a big enough coil for the cat to walk through and still sense the keyfob, that and building a flap that works at 20 below in 3 feet of snow (Well maybe a foot)
