Home Automation - System Elements

System Elements

Elements of a home automation system include sensors (such as temperature, daylight, or motion detection), controllers (such as a general-purpose personal computer or a dedicated automation controller) and actuators, such as motorized valves, light switches, motors, and others. One or more human-machine interface devices are required, so that the residents of the home can interact with the system for monitoring and control; this may be a specialized terminal or, increasingly, may be an application running on a smart phone or tablet computer. Devices may communicate over dedicated wiring, or over a wired network, or wirelessly using one or more protocols. Building automation networks developed for institutional or commercial buildings may be adapted to control in individual residences. A centralized controller can be used, or multiple intelligent devices can be distributed around the home.
