- Educational objectives
- Methodological knowledge: basic knowledge of the theoretical operating principles of the most common types of sensors and detectors and of Micro-Electro-Mechanical Systems (MEMS).Professional skills: understanding of the data sheet of common types of sensors and detectors available on the market. Ability to design a simple electronic system to interface a commercial sensor to a microcontroller connected to the internet. Use of the basic knowledge acquired in this course for continuing education in the field of the digital systems.
- Prerequisites
- The course does not require the student to pass compulsory propaedeutic exams. It exploits different physical concepts but they are introduced from the basic principles: heat flux and transmission in solids and fluids, electromagnetic radiation, Clausius-Clapeyron equation, material elestic theory, piezoresistivity, magnetic properties of materials (optional material: piezoelectricity). Moreover basic concepts and basic equations of semiconductor physics are thoroughly used.The laboratory activity is based on know how acquired in the courses of the three-year Laurea in "Informatica ed Elettronica" of the University of Perugia.
- Teaching methods
- The course is organized as follows:- face to face lectures on all issues of the course;- laboratory project. An ARM Cortex M4 prototyping board will be used. The programming environment could include i) C#-.NET MicroFramework 4.3 with Visual Studio IDE; ii) C++ e ARM mbedOS; iii) TinyCLR-OS and C#-.NET MicroFramework 4.4; iv) other platforms.The board will be connected to different types of sensors and a wireless link will be used to simulate an IoT node and interact with a data base located in the cloud.
- Other information
- No further info.
- Learning verification modality
- The exam could tentatively be organized in a oral examination including a practical discussion on interfacing a prototyping board with a sensor and transmitting the acquired data to a cloud-based data base.
