Internet of Things : The smart home

Abstract: This project report treats the basics of the rising phenomenon of Internet of Things, and the devices that can be connected to it. One of the primary goals of the project was to gain greater knowledge in the field of Internet of Things and how it can be approached form an Electrical Engineer point of view.Three types of home devices were chosen to be implemented into the Internet of Things devices. Firstly, a coffeemaker was built so it can be activated from a mobile phone. This was made possible by using cheap electronics in the form of a control board, 433 MHz receiver and a relay.In the second part of the project the window blinders was made controllable from the same application as the coffee machine. This was made possible by using similar devices and small DC servos and stepper motors. The third part of the project was to make a automated irrigation system for a flowerpot. This could be made by measuring the moisture in the soil and thereby pump water from a reservoir in to the soil. Finally a main control device was constructed to handle all the signals from the users smart phone and communicate these signals and commands to the various systems built.
