This E-block allows investigation into Home Automation. Home Automation allows messages to be sent and received via the electrical wiring system within a building. This enables communication of devices plugged into the mains power supply with no extra wiring.
The Home Automation board allows main-borne communication using a low cost controller device like a PICmicro® microcontroller found on the E-Blocks Multiprogrammer. The Home Automation Board is connected to the mains wiring system via the TTL Interface module. All devices to be controlled are plugged into separate Appliance modules. The controller, for example the Multiprogrammer, then sends simple messages to the device in order to control the state of the device. It can also receive, decode and react to incoming messages.
The Home Automation system uses modulated signals to send information via the electrical wiring system. The Appliance modules deal with all the modulation and demodulation. So the ease of use is simply by sending the appropriate messages by setting the correct bits to generate the message. An example of this is turning on a device connected to the Home Automation units. The message is simply setting the address for the message (e.g. B4) and the actual message (e.g.
B On).
All signals are X10® compatible. X10® is an emerging major standard in Home Automation
