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.
