Implementation Details
Sensor Types
- Infrared sensor/emitter pairs
Placed across a doorway, can detect in which direction a person is passing through
- Infrared motion detectors
Used as a backup system to check that a room is really "empty," so the lights don't turn off while someone is in the room
- Bluetooth RSSI
Using the device address to identify the owner, we can also use this to check which room a person is likely to be in
Applications
- Lighting control
Using the X10 protocol, we will be able to control a variety of home appliances. The appliances will need to support the protocol, but components are fairly cheap and easy to install.
- Multi-zone audio
According to user preferences, we can have an audio stream "follow" a user around the house. We could also set up default ambient noises for different rooms.
