CHAPTER 1: PROJECT BACKGROUND The Project The Internet of Things (IoT) can be described as connecting everyday objects like smart-phones, Internet TVs, sensors and actuators to the Internet where the devices are intelligently linked together enabling new forms of communication between things and people, and between things themselves. Building IoT has advanced signiFcantly in the last couple of years since it has added a new dimension to the world of information and communication technologies. Smart home is not a new term for science society, it is been used from decades. As electronic technologies are advancing, the Feld of home automation is expanding vastly. There were various smart systems have been proposed where the control is via Bluetooth, internet etc. Bluetooth capabilities are good and most of current laptop/desktops, tablets, notebooks and cell phones have built-in adaptor that will indirectly reduce the cost of the system. But it limits the control to within the Bluetooth range of the environment while most other systems are not so feasible to be implemented as low cost solution. In Wi-±i based home automation system is presented. It uses a PC (with built in Wi-±i card) based web server that manages the connected home devices. The system supports a wide range of home automation devices like fans, lights, other home appliances. A similar architecture is proposed in where the actions are coordinated by the home agent running on a PC. Other papers such as also presented internet controlled systems consisting of a web server, database and a web page of websites for interconnecting and handling the devices. The project is to design a low cost home automation design. The project presents a low cost and ²exible home control and monitoring system using an embedded microprocessor and microcontroller, with IP connectivity for accessing and controlling devices and appliances remotely using Smart phone application. The proposed system does not require a dedicated server PC with respect to similar systems and o³ers a novel communication protocol to monitor and control the home environment with more than just the switching functionality. To demonstrate the feasibility and e³ectiveness of this system, devices such as light switches, power plug, temperature sensor and current sensor can be integrated with the home control system The Project Objectives This project will focus on Smartphones enabled systems for the smart home with focus on the Raspberry Pi applications. Although many systems have been researched and proposed, very few if any have been implemented. This project aims to build on the previous research described to implement a wireless sensor network to monitor appliances in the house.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
