Case Studies in IoT - Smart-Home Solutions : Pedagogical Perspective with Industrial Applications and some latest Developments

Creative common license (CCL) based microcontroller platforms boards with various processing capacities and handling of a plethora of I/O are available in the market at various levels of complexities and prices. These CCL based microcontroller platforms boards are increasingly used, predominantly in the academia, for sensor networking as well as handling complex IoT (Internet of Things) functions. This paper looks into a case study of incorporating Arduino and Raspberry Pi for sensor networking, data transmission and enabling IoT functionalities. As a practical realization, an experimental smart home is realized with an array of sensors and a system architecture consisting of a set of Arduino and Raspberry Pi modules. The paper presents necessary aspects of codes in the form of pseudo-codes and describes some aspects of I/O with respect to the sensors used. Finally, the security problems are also addressed. Depending on the time available, a real system will be operated during the presentation of the paper.
