Elektor Home Control
The Elektor Home Control is a home automation system that works through your existing ethernet network.
All the modules run on a pic microcontroller, running the microchip TCP/IP stack. Every module is connected to a beagleboard, which doubles as a server and user interface. The beagleboard runs a modified version of Ubuntu Linux, on which python and pygtk provide the interface.
We developed 4 different modules:
- IO Board. For testing purposes
- Ledstrip board. For controlling a RGB Ledstrip
- Relay board. For switching 230 VAC devices.
- Energy meter. For measuring if a device is turned on or not(also for logging)
The IO board has 4 digital in and outputs and 2 230VAC rated in and outputs.
The relay board has 4 relays build onto it. It also features a special power supply, which transforms the 230VAC to a more suitable 5VDC. This way you don't need to use an extra power supply when using it.
Below is a video in which Koen explains in more detail what this project tries to achieve.
