Fun sketches, Gaoming! I think you first idea (hygrometer) is the most feasible and also affords you the most creativity in how it comes to life. Would you want to use a humitidy sensor in the device, or fetch humidity data from the internet? I can’t remember if IFTTT weather service provides humidity data.
The maze is a bit impractical (too much sensing required in too many places) for the scope of this project.
Your mobile idea (#3) is also feasible, but I’d encourage you to do idea #1 unless this #3 is really calling to you!
