iHome Security & Automation System2 Updated Overview: The goal of this project is to develop a home automation system that gives the user complete control over all remotely controllable aspects of his or her home. The automation system will have the ability to be controlled from a central host PC, the Internet, and also remotely accessed via a Pocket PC with a Windows Mobile based application. We do not have any ‘tangible’ test results to present in this presentation, but we will demonstrate some software we have developed.

iHome Security & Automation System12 Hardware Description-Level 0 Nodes Basic ‘cells,’ controlled by level 1 nodes. Mainly On/Off/Sensor functionality. Since L0 nodes are so varying in what kinds of functions they carry out, it is impossible to block diagram every variety, since they all contain different hardware. Generically, however, they look like this: Sensor/Switch Level 1 Node Level 0 Node Level 0 Block Diagram See next slide for comprehensive list of interface connections

iHome Security & Automation System19 Hardware Description-Level 3 Nodes Level 3 node portion of the project has been cancelled due to unexpected budget cuts. Level 3 nodes were intended for streaming video between the central server, TVs, and video cameras. This would require expensive hardware that is now not able to be purchased or developed.
