Home Automation
Very simply home automation is the control of any electrical appliance within your home either locally or remotely from anywhere in the world.
This includes, lighting, power, heating, air conditioning, blinds and curtains, security systems- intruder, fire, flood, etc. watering systems, gates, door locks, windows, pc’s, televisions, sound systems, in fact anything you need to do manually can be done automatically.

Although many techniques used in building automation (such as light and climate control, control of doors and window shutters, security and surveillance systems, etc.) are also used in home automation, additional functions in home automation can include the control of multi-media home entertainment systems, automatic plant watering and pet feeding, automatic scenes for dinners and parties, and a more user-friendly control interface.
In extreme installations, rooms can sense not only the presence of a person but know who that person is and perhaps set appropriate lighting, temperature and music/TV taking into account day of week, time of day, and other factors.
Other automated tasks may include setting the air conditioning to an energy saving setting when the house is unoccupied, and restoring the normal setting when an occupant is about to return. More sophisticated systems can maintain an inventory of products, recording their usage through an RFID tag, and prepare a shopping list or even automatically order replacements.

Some practical implementations of home automation are for example when an alarm detects a fire or smoke condition, then all lights in the house will blink to alert occupants. If the house is equipped with a home theater, a home automation system can shut down all audio and video components to alert the user to a possible fire or a burglar.
