To determine

Choose the correct answer among the given choices to find which is referred as a type of home automation system.

Answer to Problem 1R

The correct answer among the given choices that referred as a type of home automation system is “$\underset{\_}{\text{a}.\text{X10}}$”.

Explanation of Solution

Discussion:

Option (a):

X10 technology is the oldest technology that was invented in 1975 in Scotland. X10 technology is used in the home automation systems. The patent of X10 technology expired in 1997; after that, it became an open standard technology for the manufacturers to implement in their products.

Especially, X10 home automation system is used in existing homes for retrofit wiring since it is simple, low cost, and will not require a special wiring for basic functions. It is one-way communication system. The components can be added easily to the system such as audio/video, lightening, and arming; whereas some devices can “talk” and others can “listen” and are often referred to as “plug-and-play” system. Since X10 is one type of home automation system, option (a) is correct.

Option (b):

X20 technology is an automation technology which is used effectively in the automation of machines or systems in manufacturing, but not in the home automation systems. For example, X20 automation can be used in industrial PCs. It is simple to connect and configure. This type of automation is a better choice than a remote control I/O system. Since X20 is not a type of home automation system, option (b) is incorrect.

Option (c):

HAS is one of the highly automated and powerful system which is used in production process as well as in research projects. It is a high cost automation system. Since HAS is not a type of home automation system, option (c) is incorrect.

Conclusion:

Thus, the correct answer among the given choices that is referred to as a type of home automation system is “$\underset{\_}{\text{a}.\text{X10}}$”.
