với phần cứng cao, và hệ thống mã nguồn mở lớn cho phép người lập trình xây dựng ứng dụng “nhúng” một cách dễ dàng. Bên cạnh đó, người sử dụng có thể xây dựng một hệ điều hành cho riêng mình, đây là thế mạnh của Linux nó giúp cho mỗi cơ quan, tổ chức, hay một quốc gia | 12 Part I Bringing the Future Home__ 1 Motion sensors Motion sensors can signal when motion is detected and you can set a motion sensor s transceiver to send X10 signals to X10 modules for instance to turn on lights or to an appliance such as a camera . Other sensors Water sensors can detect leaks and cause a chime to sound for example and rain sensors can delay the watering of your lawn. They operate similarly to motion sensors. Touchtone controller This item controls X10 modules through touchtone signals so you can control your system via your phone. Desktop controller This inexpensive controller plugs into the wall and can control 8 to 16 X10 modules without a transceiver. Computer You can control your X10 modules via your computer software in the following ways Send and receive X10 signals over the powerlines from your computer. For example the CM11A computer interface as shown in Figure 1-2 can control your modules by using Linux home automation software. A starter kit is available from for . Enable your computer to function as a remote control. The Firecracker computer interface also called CM17A is compatible with Linux home automation software. This is one-way communication only. A starter kit is available from for . Figure 1-2 You can use the CM11A X10 computer interface with free Linux software to control your X10 modules. Chapter 1 Exploring the Possibilities of Home Automation 13 Controlling X10 modules with Linux software By computerizing your X10 system you gain the power to create sophisticated macros that can operate based on the input of more than one X10 device such as opening the garage door if motion is sensed by the hall closet where you keep your coat between the time of 8 00 and 8 15 . Or you can connect your system to the Internet so you can operate it from anywhere in the world without having to pay for a phone call. With your computer controlling your .
