IoT (Internet of Things) is a border area of embedded systems and network informatics that gets more and more in focus in today’s world. This thesis leads through the design procedure of such system. The target objective is to design a „smart room”, in which the communication between the user and the nodes – providing low-level sensor and actuator functionalities – is performed via a platform independent, easy-to-use interface, through a common network that can be found in everyone’s homes.

In the focus of the system stands the mood lighting implemented with intelligent LED-strips, and the detection of entering or exiting the room, but it is completed with further sensors, like temperature, relative humidity, sound level, and ambient light. The values can be read and the lighting can be controlled on the graphical user interface. The system implements higher-level functionalities, like automated LED control triggered by the events of entering the room or detecting the sound of two claps.

After a brief introduction, the thesis shows the structure of the whole system, and then describes the chosen devices, explaining the decisions for choosing. After that, the problems experienced throughout the planning and implementation, their solutions, and the complex design decisions will be described. Thereafter, the implementations of the hardware and software subsystems can be read. In the end follows a short summary of the work, showing the results achieved, and the potential improvement possibilities.
