The home automation needs to make use of latest and advance technology to makes it flexible, reliable and cost effective. Home automation involves introducing a degree of computerized or automatic control to certain electrical and electronics system in a building. The popularity of home automation has been increasing greatly in recent years due to much higher affordability and simplicity through smartphone and tablet connectivity. Most research aims to design and develop home automation system which is wireless and can be controlled via a multiple way to give more accessibility and control over a wide range of the systems. The main purpose is to develop and design an automation system which is accessible remotely to monitor and controlling it in a user-friendly way. Wireless communication in home automation systems is focused on low-power wireless communication modules. This paper proposes a cost-effective home automation system which is contains a combination of Android smart phone or tablet or a laptop and embedded system which include Arduino Due Board, Ethernet Shield module and Relay circuit. Also, most researches use an open source or a payed software to be used under Android media of the smart phones, but here the required interface Android pages are designed and implemented by researcher which reduce the cost of the proposed system effectively.

In Industries, it’s always look forward to reducing their operational cost and their Critical infra structures. Therefore, companies search for solutions to reduce their cost and ensure the system efficiency. One of that solutions is the use of a Cloud computing system which offers the advantage of integrating CPSs such as SCADA systems. This paper proposed a cost effective, simple, reliable and secured Cloud SCADA system. The proposed Cloud SCADA System based on secured nodes was implemented, which connects each other through VPN channel “encrypted’’ to ensure the isolation of our system form external attacks. The remote terminal unit (RTU) also connected to master terminal unit (MTU) through unit encrypted VPN channel, so in our system, when the end user need to connect to MTU the firewall of our system protect on MTU from un-recognized end point users. Comparing the cost of our system with pervious work, it’s lower than Arduino + WI-FI method by five times and 13 times lower than Raspberry-PI method. Also comparing with other server options the proposed server is easy for using, available for adding new components and also has high security.
