Objectives
THE COURSE ADDRESSES ISSUES RELATED TO THE MEASUREMENT AND MEASUREMENT OF PHYSICAL QUANTITIES USING SMART TRANSDUCERS. FIRST, THE PROBLEMS RELATED TO MEASUREMENT PERFORMANCE ARE ADDRESSED, THEN, THE PHYSICAL PRINCIPLES OF TRANSDUCTION OF THE MAIN PHYSICAL QUANTITIES WILL BE PRESENTED. NEXT, THE OPERATING PRINCIPLE OF SMART TRANSDUCERS, THE PHYSICAL MODEL, THE METROLOGICAL CHARACTERISTICS, THE MAIN IMPLEMENTATION TECHNOLOGIES, AND THE MICROPROCESSOR HARDWARE ARCHITECTURE ARE EXPLAINED. THE APPLICATION OF NEW EDGE AND CLOUD COMPUTING TECHNIQUES TO SMART TRANSDUCERS WILL BE CONSIDERED. FINALLY, THE IEEE 1451 STANDARD AND ITS USE IN INDUSTRY 4.0 WILL BE INTRODUCED.

KNOWLEDGE AND UNDERSTANDING SKILLS
UPON COMPLETION OF THE COURSE, THE STUDENT WILL KNOW:
- THE THEORY OF MEASUREMENT AND MEASUREMENT UNCERTAINTY;
- THE ANALYSIS AND EVALUATION OF STATIC AND DYNAMIC CHARACTERISTICS OF A MEASUREMENT SYSTEM;
- TECHNIQUES FOR TRANSDUCTION AND CONDITIONING OF MEASUREMENT SIGNALS INTO BASIC ELECTRICAL QUANTITIES;
- SMART SENSOR ARCHITECTURES;
- CONTACTLESS MEASUREMENT TECHNIQUES: COMMUNICATION BUSES IN INDUSTRY (CAN BUS).
- THE IEEE 1451 STANDARD.
APPLIED KNOWLEDGE AND UNDERSTANDING SKILLS
UPON COMPLETION OF THE COURSE, THE STUDENT MUST:
- KNOW HOW TO EVALUATE THE RELIABILITY OF A MEASUREMENT;
- EVALUATE THE PERFORMANCE OF DIFFERENT SENSOR-BASED SYSTEMS;
- EVALUATE THE FEASIBILITY OF SMART SENSOR-BASED SYSTEMS;
- ESTIMATE THE PERFORMANCE OF DIFFERENT COMMUNICATION BUSES;
- QUANTIFY THE PERFORMANCE OF NON-CONTACT MEASUREMENT SYSTEMS.
AUTONOMY OF JUDGMENT
THE STUDENT WILL BE ABLE TO IDENTIFY THE MOST APPROPRIATE METHODS TO:
- DESIGN A TRANSDUCTION AND CONDITIONING SYSTEM FOR DIFFERENT PHYSICAL QUANTITIES;
- SIZE COMMUNICATION SYSTEMS IN INDUSTRIAL SETTINGS;
- DESIGN WIRELESS SENSOR NETWORKS;
- DESIGN A MACHINE VISION-BASED MEASUREMENT SYSTEM.

COMMUNICATION SKILLS
BE ABLE TO WORK IN GROUPS AND BE ABLE TO DESCRIBE, ORALLY AND IN A CLEAR AND CONCISE MANNER, ON TOPICS RELATED TO TRADITIONAL AND INNOVATIVE MEASUREMENT SYSTEMS.

LEARNING SKILLS
BE ABLE TO APPLY THE KNOWLEDGE ACQUIRED TO CONTEXTS DIFFERENT FROM THOSE PRESENTED DURING THE COURSE, AND IN PARTICULAR:
- DELVE INDEPENDENTLY INTO THE TOPICS COVERED, ALSO MAKING USE OF MEDIA OTHER THAN THOSE RECOMMENDED;
- ALSO APPLY THE ACQUIRED KNOWLEDGE TO CONTEXTS DIFFERENT FROM THOSE COVERED IN THE COURSE.

Prerequisites
FOR THE SUCCESSFUL ACHIEVEMENT OF THE SET OBJECTIVES, KNOWLEDGE RELATING TO THE STUDY OF ELECTRICAL AND ELECTRONIC CIRCUITS, MATHEMATICAL ANALYSIS, THE BASICS OF SIGNAL THEORY IS REQUIRED.

Teaching Methods
THE COURSE INCLUDES THEORETICAL LESSONS SUPPORTED BY CLASSROOM EXERCISES AND LABORATORY EXERCISES. IN THE EXERCISES THE STUDENT IS PROPOSED TO SOLVE PROBLEMS RELATING TO THE TOPICS COVERED IN THE THEORETICAL LESSONS. DURING THE LABORATORY EXERCISES FORESEEN IN THE FIRST PART OF THE COURSE, THE STUDENTS ARE ASKED TO SOLVE PROBLEMS THAT REQUIRE THE APPLICATION OF THE TECHNIQUES EXPLAINED IN CLASS, IN THE FOLLOWING EXERCISES, THE STUDENTS, DIVIDED INTO WORKING GROUPS, ARE ASSIGNED A PROJECT TO DEVELOP . THE PROJECT INCLUDES ALL TEACHING CONTENTS IN A UNIFIED MANNER AND ALLOWS STUDENTS TO ACQUIRE THE SKILLS OF DESIGNING, BUILDING AND CHARACTERIZING A SENSOR-BASED MEASURING INSTRUMENT
Verification of learning
THE DEGREE OF LEARNING IS ASSESSED BY MEANS OF AN EXAM CONSISTING OF AN ORAL INTERVIEW WITH AN INDICATIVE AVERAGE DURATION OF ABOUT 40 MINUTES DURING WHICH THE SYSTEM IMPLEMENTED WILL ALSO BE DESCRIBED. THE MARK, EXPRESSED OUT OF THIRTY (THE MINIMUM PASSING LEVEL CORRESPONDS TO "18" AND THE MAXIMUM TO "30 CUM LAUDE"), WILL DEPEND ON THE MATURITY ACQUIRED ON THE COURSE CONTENTS.
IN PARTICULAR, THE EXAM IS AIMED AT:
- VERIFY THE LEARNING OF THE TOPICS COVERED IN THE THEORY HOURS;
- VERIFY THE ABILITY TO PRESENT THE TOPICS ADDRESSED;
- VERIFY THE SUCCESS OF THE GROUP PROJECT CARRIED OUT ON THE TOPIC ASSIGNED BY THE TEACHER;
- VERIFY THE AUTONOMY OF JUDGMENT IN PROPOSING THE MOST APPROPRIATE APPROACH TO ARGUE WHAT IS REQUESTED.
TO PASS THE EXAM (MINIMUM GRADE 18), IT IS NECESSARY TO ACHIEVE SUFFICIENCY BOTH IN VERIFYING THE LEARNING OF THE TOPICS COVERED IN THE THEORY HOURS AND IN THE SOLUTION OF ANY PROPOSED MEASUREMENT PROBLEM.
THE MAXIMUM LEVEL (30) IS ATTRIBUTED WHEN THE STUDENT DEMONSTRATES A COMPLETE AND IN-DEPTH KNOWLEDGE OF THE VARIOUS TOPICS COVERED IN THE THEORY HOURS.
FURTHERMORE, FOR THE PURPOSES OF HONORS, THE FOLLOWING WILL BE TAKEN INTO ACCOUNT:
- THE QUALITY OF THE EXPOSURE, IN TERMS OF THE USE OF APPROPRIATE SCIENTIFIC LANGUAGE;
- THE ABILITY OF TRANSVERSAL CORRELATION BETWEEN THE DIFFERENT TOPICS OF THE COURSE AND, WHERE POSSIBLE, WITH THOSE OF OTHER DISCIPLINES;
- THE AUTONOMY OF JUDGMENT DEMONSTRATED.
