Advancement in IoT based application has become the cutting edge innovation among the researcher due to the accessibility of Internet all over. In order to make the application user friendly, many new age technologies, web based and android based technologies have acquired their significance in this cutting edge technology. In recent years, the world has seen a lot of progress in automated home systems. The existing home automation systems are basic: turning switches on/off, etc. over the Internet. But this leaves a lot to be desired in the Home Security department. While there are systems that let you view your security camera feed, this is highly time consuming and counter-productive. There are numerous electrical equipment’s available in market which could be integrated together to create a robust solution which will address the security gaps and provide automation at finger tips. The currently available Home automation systems are very expensive and not within the reach of common man. This paper helps in providing cost effective robust Home Security automation using Raspberry. It also helps in energy conservation and empowering user to control using smart phone. Thus, main objective of this work is to make our home much secure along with energy conservation
