detecting animals using rfid
Hi feiutm9898,
I was thinking to do RFID also, BUT i know how difficult it is to do that, and the anntena will be pretty big if i want it to convert the RF into power.
You can build a small transmitter with a battery, but then you will need to decode the incoming signal and your battery will run out quite fast form all the RF noise...
So, If you will read the artical you will see that the person how worte it spent some time thinking about this problems, and thats the best way he came up with.
If you have a better idea on overcoming your pet carynig a car battery, i will be more then happy to hear about it.
Good luck.
