Proximity sensor for dog door ?

[Normnet]

I did testing of the Honeywell SS441 on the bench and max range is only about 1 inch. And that's with very strong neo magnets so I'll order some hmc1001's.

And I'm still looking for RFID units with decent range.

SkyeTek is the closest RFID I have found so far but I am still looking for a good 2' range unit a the lower price point.
