Sensors and Vision

I.     Course Prefix/Number: MFG 139

       Course Name: Sensors and Vision

       Credits: 3 (2 lecture; 2 lab)

II.    Prerequisite


III.   Course (Catalog) Description

This course examines various forms of sensors and machine vision technology commonly used in industry today for automating machinery. Students will see how sensors and vision systems work and how they are applied, including limit switches, proximity sensors, photoelectric, ultrasonic, vacuum, pressure, and temperature. Most sensors are input to programmable logic controllers (plc’s) so we will investigate those also. Hands on projects are part of this course.

IV.   Learning Objectives

The main objective is to develop the student’s ability to analyze and solve problems in a lab environment utilizing sensors and vision systems. The emphasis is on the correct understanding of industrial sensors and vision systems theories of operation and competencies utilized in programming and setting up this type of equipment.

V.    Academic Integrity and Student Conduct

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton's Code of Academic Conduct. This code prohibits:

• cheating,
• plagiarism (turning in work not written by you, or lacking proper citation),
• falsification and fabrication (lying or distorting the truth),
• helping others to cheat,
• unauthorized changes on official documents,
• pretending to be someone else or having someone else pretend to be you,
• making or accepting bribes, special favors, or threats, and
• any other behavior that violates academic integrity.

There are serious consequences to violations of the academic integrity policy. Oakton's policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.

Please review the Code of Academic Conduct and the Code of Student Conduct, both located online at
