how to make room sensor ?

Do you want to make a 3D model of a room with a camera? Blender (video game software can help with that?

You have eyes - look through the door.

Can you see walls and a ceiling? Then it's a room!

I would have NO idea how to sense room - Perhaps some kind of capacitive spatial volume sensor?

Maybe by testing the echo.

:-) Your question is vague in the extreme!.

You can make a buy a PIR sensor that can detect humans.

Or do you want to sense the presence of rooms ?.
