SummarySummary

The Home Enhancement Suite is a package that will control various aspects of a room in an autonomous fashion when a user is recognized through RFID. Currently, there are home automation kits available, but generally these do not incorporate different settings for different people. The Home Enhancement Suite will allow a user to automate the lighting as well as set up an HDMI product, such as a television, to their favorite channel and volume.

Updated PSSCsUpdated PSSCs

1. An ability to detect a user based on RFID and determine which user has priority, displaying the user's identity on an LCD.

2. An ability to adjust the light intensity to match a user’s settings through X10 protocol.

3. An ability to adjust a television set or other HDMI device using CEC-HDMI protocol, to a user's preferred settings. (ON/OFF, Channel, Volume)

4. An ability to unlock a door when an acceptable RFID is present.

5. An ability to select/set preferred settings through a computer program and the ability to save the "light settings" with the press of a button.
