I am thinking of an automatic window(windows in houses).
I've seen a device which opens a window when temperature changes. I am thinking of adding more features for that window.
1. The window will open/ close at designated times(opens in the morning closes at dusk).
2. The window will automatically close when it is raining.
3. The window will open when the temperature inside the room raise at a certain temperature.
4. The given features can be controlled using a mobile phone or maybe a remote.
Well, those are for other circumstances. For example, the temperature is very hot and the window automatically opens and then there is a very unpleasant smell outside you will want to close it.
Not a very cool example. But I think you got the point?
I think it would be quicker to open/close the window manually rather than get out a phone, dial up, enter a PIN code (you'd need a PIN otherwise anyone could get control of the window) then use the open/close command
