1. Happy Home Helper Final Status Presentation Jeremy Searle Apr 20, 2004

2. Background  Home Automation is used for various household controls (lights, security, entertainment)  Systems tend to be expensive  Systems completely rely on the home PC which can be unreliable (Hackers, Crash, Power Surge, Virus)  Systems must be programmed to accomplish tasks and do not learn

3. Problem Statement To design a home automation system that is capable of learning and executing daily routines at an economical cost.

4. Solution  Central micro-controller unit  Outlet control modules  PC user interface  Sensors to control lights/sense walking path  Remember routines by averaging sensor data and user input data  Wireless communication between devices  Computer controlled window and door mechanisms

5. System Overview Central μController Outlet Module Data Flow Human Input Misc. Sensors

6. System Functionality Goals For Final Demonstration: -Combine central μ-controller and outlet module functions into one unit -Have a working blind actuator prototype with a light sensor NOT in Final Demonstration: -Window opening actuators -Wireless communications -Sensors from outlet modules -Learning (this would be in software for the PC, but basic functions take precedence over this advanced feature)

7. Outlet Module Overview Serial Input/Output to/from Central μController Power from wall outlet Current Sensor Relay Device to be controlled by Outlet Module μController AC/DC converter Serial Input/Output to/from Peripherals (sensors, actuators)

8. Outlet Module Functionality Goals For Final Demonstration: -Current Sensor to be able to report power consumption -Relay to be remotely controlled by PC interface NOT in Final Demonstration: -Integrated power supply -The ability to control only one receptacle of the two present -Peripheral Serial Bus for sensors -Serial Bus to/from HC08

9. Central Micro-Controller Overview Serial Input/Output to/from Outlet Modules Serial Input/Output to/from PC NVRAM uController RTC

10. Central Micro-Controller Functionality Goals For Final Demonstration: -Two way communication with PC NOT in Final Demonstration: -NVRAM -Real Time Clock -Serial Communications to/from outlet modules
