Objectives
THE COURSE AIMS TO PROVIDE THE STUDENTS WITH A SOUND METHODOLOGICAL BASE FOR UNDERSTANDING THE FUNCTIONAL CHARACTERISTICS OF SENSORS AND ACTUATORS THAT INTERFACE WITH MICROCONTROLLERS FOR IOT APPLICATIONS.


KNOWLEDGE AND UNDERSTANDING
TO KNOW THE WORKING PRINCIPLE OF THE MOST COMMON TYPES OF SENSORS, ACTUATORS. TO KNOW THE MAIN CIRCUITS AND METHODS FOR INTERFACING SENSORS AND ACTUATORS WITH THE EMBEDDED SYSTEMS THAT ARE MORE COMMONLY USED IN INDUSTRIAL APPLICATIONS.

APPLYING KNOWLEDGE AND UNDERSTANDING
TO CHOOSE THE PROPER SENSORS AND ACTUATORS FOR SOME INDUSTRIAL APPLICATIONS, TO KNOW HOW TO INTERFACE THEM WITH AN EMBEDDED SYSTEM. TO DESIGN AND IMPLEMENT SIMPLE CONTROL SYSTEMS BASED ON MICROCONTROLLERS FOR IOT APPLICATIONS.
Prerequisites
FOR THE SUCCESSFUL ACHIEVEMENT OF THE OBJECTIVES, BASIC KNOWLEDGE OF CIRCUIT THEORY AUTOMATIC CONTROLS END EMBEDDED SYSTEM ARE REQUIRED.

TOTAL LECTURE/PRACTICE/LABORATORY HOURS 22/2/24
Teaching Methods
THE COURSE INCLUDES THEORETICAL LESSONS, EXERCISES AND A SIGNIFICANT PART OF EXERCISES ON HARDWARE IN LABORATORY. PRACTICES COMPLETE THE THEORETHICAL LESSONS AND THEY ARE AIMED AT ASSESSING THE KNOWLEDGE OF SENSORS AND TRANSDUCERS, AS WELL AS THEIR INTERFACING WITH EMEBDDED SYSTEMS. A FIRST PART OF THE EXPERIMENTAL TESTS IS DEDICATED TO THE ANALYSIS OF THE HARDWARE AND TO BASIC CASE-STUDIES. AFTERWARDS, STUDENTS WORK AUTONOMOUSLY, IN SMALL GROUPS, WITH THE SUPPORT OF THE TEACHER.
Verification of learning
THE EXAM IS AIMED AT ASSESSING THE WHOLE KNOWLEDGE OF THE CANDIDATE: UNDERSTANDING OF WHAT EXPLAINED DURING THE LESSONS, APPLYING SOME GIVEN CONCEPTS TO NEW CASES INCLUDING AN EMBEDDED SYSTEM WHICH HAS TO BE INTERFACED WITH SENSORS AND ACTUATORS, THE CRITICAL EVALUATION OF THE RESULTS, THE ABILITY TO EXPLAIN CONCEPTS. THE CANDIDATE HAS TO EXPLAIN ORALLY THE RESULTS OF THE PRACTICAL ACTIVITY THAT HE/SHE DID IN LABORATORY ON THE PROJECT ASSIGNED TO HIM/HER.

THE MINIMUM MARK (18) IS ASSIGNED TO THE STUDENT WHO DEMONSTRATES A BASIC KNOWLEDGE OF SENSORS, ACTUATORS AND OF THE MAIN CIRCUITS FOR ELECTRICAL SIGNALS CONDITIONING PRESENTED IN THE COURSE.

THE MAXIMUM MARK (30) IS ASSIGNED TO THE STUDENT SHOWING THE ABILITY OF APPLYING THE CONCEPTS DISCUSSED IN THE COURSE ALSO TO CONTEXTA MORE WIDE THAN THOSE ONES TREATED IN THE COURSE THEREOF.

THE LAUDE IS ASSIGNED TO THE STUDENT SHOWING A ROBUST KNOWLEDGE OF THE METHODOLOGICAL AND APPLICATIVE CONTENTS OF THE COURSE, PRESENTING THE TOPICS WITH A HIGH ABILITY AND BY ELABORATING CONCEPTS AUTONOMOUSLY AND IN CONTEXTS THAT ARE SIGNIFICANTLY DIFFERENT FROM THOSE ONES PROPOSED BY THE PROFESSOR.
