Architecture

The gumstix motherboard is responsible for monitoring one doorway. Each sensor and each appliance is controlled by a single gumstix board. The gumstix boards coordinate with each other to maintain the entire house.

Optionally, other control nodes such as a Bluetooth-enabled computer or cell phone can be added. These would provide more accessible user interfaces to directly control user preferences and settings.
