The Poms will climb the stairs, especially when they are lonely. This is a big problem, as it isn't safe, and they are too small to be able to get back down.
At the minute we have a turned over drying rack blocking them, this is obviously inconvenient.
I'm thinking of putting an arduino hooked up to a loud alarm at the bottom of the stairs. The big problem is what sensor to use that can distinguish between dogs and humans. A system with two IR or laser trip wires might work. I don't think any of the microwave presence sensors distinguish between humans and dogs, despite the massive size difference.
I was thinking of doing something with OpenCV, but I don't know how production ready it is.

Cheap and easy to set up. You could also calibrate a passive infrared system since a dog's body has a higher body heat than a humans, but you could also just wire some electrostatic sensors so that they don't trip the alarm unless only one set of sensors is tripped in a certain time period. That is, have one set at about 5 feet, so if a human walks through, both the low one and high one are given feedback, which doesn't trip the alarm.
Should be cheaper than lasers.

I haven't seen any electrostatic sensors for arduino or anything. Also doubt cheap little arduino PIRs would be able to be calibrated that finely, they're just simple little things. I do have two PIRs, but I think it would be gimmicky to get running right.
The lasers I am referring to are just the little diode + lens ones, they cost next to nothing.

Why not a baby gate that swings open at the bottom of the stairs? U dont even need to latch it close.

Do you have like a puppyfarm or something OP?
