Survey on: Home automation systems

Internet of Things (IoT) is nothing but connecting different real world objects to provide proper communication, synchronization, and inter-conneting between various devices or physical appliances is also known as "Things". The Home Automation System (HAS) is extension of current activities performed inside the home and this Home Automation System (HAS) can be developed easily now a day's, because of powerfull computational devices and wireless sensor network(WSN), to provide user friendly and cost fairly home automation system. In home automation system (HAS), different technologies like WiFi, Bluethoot and ZigBee are used for communication, and different devices like smart phone, tablet and laptop used for controlling various appliances. In this paper we detailed a survey on different home automation systems considering parameters like type of communication, cost, technology and efficiency of system. A comparative analysis of home automation systems is done. In future this system may have high demand and usage for automation of the "Things". Using Home Automation System (HAS) our home will be smart home that can operate without any physical interferrence of human being.
