Hi ES,
This is really off topic, need some advice
So, I have 3 cats (two black and one white), the black cats (Punch, Baby)
are brother and sister they are in good shape,
The problem is with the white one (Mio) she is really fat, it looks like she's pregnant
.
I want to put Mio on a diet without Hurting Punchs and Baby's diet, it is not possible for me to find them separately.
My question is for a proximity sensor that will recognise the collar on the cat and will open
a door where the food will be, i sow some proximity switches on ebay but there trigger range is 10 mm or less,
i need around 10 cm (4 inch) trigger range.
Any suggestions are welcome :wink:
