Home automation strategically involves controlling home appliances through an automated system making it convenient for its users. This advancement in technology makes a person’s life easier as it can save energy by utilizing the devices accordingly. The lighting system such as lights can be dimmed with a remote control or a complex function can be performed such as setting up a network of items inside your home that are programmed in a way that these can be controlled by the use of your cell phone from any place around the world.
Home automation system also includes switching off electrical appliances such as air- conditioners or refrigerators or home heaters, when they reach desired temperatures; they also have the capacity to switch on or off again when the temperature has crossed a certain limit. The automation system helps to keep your house secured from burglars by transmitting signals to the nearest police station and the home-owner if by any means a trespasser is sensed.
Wide Range of Options
This type of system can either be centralized or programmable, or it may consist of decentralized and isolated sensors and controls. These systems categorize from sophisticated electronic programmable controls that are used for lightening, cooling, heating and also to operate entertainment devices by the use special wiring or wireless, and some have motion sensors that control lighting systems. Some of the systems could be highly expensive and so these are designed in a way that they are energy efficient. So the reduced energy costs take ample of time to pay back the savings.
There are certain considerations taken into account while designing and developing a home automation system, and this highly depends on the need of the users. As you have endless possibilities in which you can design your automation system accordingly to suit your personal requirements. Following should be kept in mind:-
#1. Type of Interface- The most basic requirement in home automation systems in the designing of the interface in such a way that the basic communication protocol is followed and a hardware set- up that is used to send and receive messages between the devices and the user. As designer have many options to execute communication between devices, the user, and the overall system, as a lot depends on the size of the house and the range and system. The user can control its appliances through the internet, for which the designer needs to set internet/ Wi-Fi interface as a system that connects the system to a home network. And if the user wants to connect via Bluetooth from a cell phone, the user needs to set up Bluetooth as an interface. The choice of technology used in terms of central control unit (CCU) and Room control units (RCU).
#2. Sensing Requirements- The designer also need to take into account the sensing requirements of the user and it can depend on the sensor to perform the task. As the user needs to assess the sensor specifications that are required for different needs that suit the usability to adapt to different environments. There is certain range of sensors that include:-
- Thermostats are basically used to control air conditioners, geysers, refrigerators, heating system or in the case of fire.
- Humidity sensors are designed to sense the moisture level in the environment.
- Light sensors can be installed to detect and read the luminous intensity in the household.
- Gas sensors are designed to detect gas leakages.
As the information generated by these sensors is used by the processor to make his decisions regarding his action for appliances as to whether switching them OFF or ON.
