  1. iHome Automation System Home Automation System Team: Million Dollar ContingencyRegiment Adam Doehling Chris Manning Ryan Patterson

  2. 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 System

  12. 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: Level 0 Block Diagram Level 1 Node See next slide for comprehensive list of interface connections Level 0 Node Sensor/Switch iHome Security & Automation System

  13. L1 Device Interface • All L0 Nodes connect to the system via L1 nodes using the following L1 ports: • Eight TTL Output Ports (5V) • Four TTL Input Ports (5V) • Three Analog Input Ports (3.3V) • Four PWM Output Port (5V, resolution of 33,300) • 127 Channel I2C Port (3.6V) • Two SPI Ports (3.6V, 1mbps) • One digital quadrature encoder input (5V) iHome Security & Automation System

  19. 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. iHome Security & Automation System

  20. Software Overview Recall: • There are three main software applications in this project: The iHome Control Center, the Remote Control Center, and the Webserver Webserver Remote Control Center iHome Control Center iHome Security & Automation System
