Smart Home Concept
Smart Home refers to the use of computer and information technology to control home appliances and features (such as windows or lighting). Systems can range from simple remote control of lighting through to complex computer/micro-controller based networks with varying degrees of intelligence and automation. Smart Home is adopted for reasons of ease, security and energy efficiency.
In modern construction in industrialized nations, most homes have been wired for electrical power, telephones, TV outlets (cable or antenna), and a doorbell. Many household tasks were automated by the development of specialized Smart appliances. For instance, automatic washing machines were developed to reduce the manual labour of cleaning clothes, and water heaters reduced the labor necessary for bathing.
The use of gaseous or liquid fuels, and later the use of electricity enabled increased automation in heating, reducing the labour necessary to manually refuel heaters and stoves. Development of thermostats allowed more Smart control of heating, and later cooling.
As the number of controllable devices in the home rises, interconnection and communication becomes a useful and desirable feature. For example, a furnace can send an alert message when it needs cleaning, or a refrigerator when it needs service. If no one is supposed to be home and the alarm system is set, the home Smart system could call the owner, or the neighbours, or an emergency number if an intruder is detected.
In simple installations, Smart Technology may be as straight forward as turning on the lights when a person enters the room. In advanced installations, rooms can sense not only the presence of a person inside but know who that person is and perhaps set appropriate lighting, temperature, music levels or television channels, taking into account the day of the week, the time of day, and other factors.
Other Smart tasks may include reduced setting of the heating or air conditioning 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 bar codes, or an RFID tag, and prepare a shopping list or even automatically order replacements.
Smart Home can also provide a remote interface to home appliances or the Smart system itself, to provide control and monitoring on a smartphone or web browser.
An example of remote monitoring in Smart Home could be triggered when a smoke detector detects a fire or smoke condition, causing all lights in the house to blink to alert any occupants of the house to the possible emergency. If the house is equipped with a home theatre, a Smart home system can shut down all audio and video components to avoid distractions, or make an audible announcement. The system could also call the home owner on their mobile phone to alert them, or call the fire department or alarm monitoring company.
