"Sensor Manufacturing and Process Control" can also be taken for academic credit as ECEA 5343, part of CU Boulder’s Master of Science in Electrical Engineering degree.
This is our fourth course in our specialization on Embedding Sensor and Motors. To get the most out of this course, you should first take our first course entitled "Sensors and Sensor Circuits", our second course entitled "Motor and Motor Control Circuits", and our third course entitled "Pressure, Force, Motion, and Humidity Sensors". Our first course gives you a tutorial on how to use the hardware and software development kit we have chosen for the lab exercises. Our second and third courses give you three hands-on lab experiments using the kit. This third course assumes that you already know how to use the kit. You will learn about sensor signal characterization and manufacturing techniques and how to optimize the accuracy of sensors. You will also learn about more advanced sensors, proportional-integral-derivative (PID) control, and how this method is used to give you a closed loop sensor feedback system. After taking this course, you will be able to: ● Understand how sensor manufacturers characterize and calibrate their sensors. ● Tune a PID control loop and access the PID control function of the Cypress PSoC development kit for a motor control application. ● Understand manufacturing methods used to build electro-mechanical and micro-machined sensors. This course includes specific hardware and software requirements. Please review the FAQ below for complete details.
In module 1 you will learn how companies perform process control in their factories. First, you will review how 2nd order transfer functions work, which is the theoretical basis for much of process control. Then you will learn how plant-wide control systems are implemented and details about the software protocols used to communicate between plant controllers and sensors. Then you will perform a lab for PID control with your PSoC system, which will get you some hands-on experience with this type of control system.

In module 2 you will learn how sensor software is adjusted for optimal performance in the field. First, you will review how non-linear sensor response curves are linearized for more predictable performance. Then you will learn how sensor output is automatically adjusted to account for wide ranges of ambient temperature. Next, you will review how sensors are calibrated, and the certification procedures that companies follow to demonstrate calibration capability. Afterwards, you will study how linearization, compensation, and calibration play into sensor accuracy specs. Finally, you will perform a lab for closed loop motor control with your PSoC system, which will get you some hands-on experience with closed loop systems.

In module 3 you will first learn how radar level transmitters work, and how they are used to provide accurate readings in all types of process tank conditions. Then you will learn about components and design issues for LIDAR systems used in self driving vehicles. Afterwards, we will teach you about how sensors are customized for medical applications. This includes pressure and temperature sensors that are implanted during surgical procedures, as well as pressure and flow sensors used in patient care equipment.

In module 4 you will learn how sensors are manufactured. First you will learn how MEMS construction is used to make miniature flow, pressure, and temperature sensors. Afterwards, we will teach you how micro-electronic connections attach the MEMS sensors to connections within plastic encapsulated chips. Then we will discuss how sensor chips are enclosed within sensor housings, and how different designs of housings are used for different applications. Then you will learn how sensors are tested for high reliability in the field.

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
