Can anyone recommend a proximity sensor to help me train sneaky dogs?
Scenario: dogs sneak into the laundry room and jump up on the counter to eat the cat food (and "snack" in the litter). We leave the door cracked 4 inches so the cats can get in, but the dogs can push by the obstruction with ease. Cat door is no good as one dog could fit through that... and the door would look ugly with that on there.
Solution: I would like to attach a tag to the dog's collar. I need a sensor that can detect the tag within approximately 3 feet. When the sensor detects the tag, I want to trigger a loud siren until it no longer senses the tag presence.
I am a total noob to this stuff. Can anyone recommend a solution (same or similar) that doesn't cost a fortune? I currently have no home automation or security implementations... willing to start. Any suggestions to point me in the right direction is greatly appreciated.
