In the ever-evolving world of embedded systems and IoT, understanding sensors is paramount. Recently, I completed Coursera’s “Sensors and Sensor Circuit Design” course, and I can confidently say it’s an invaluable resource for anyone looking to delve into the practicalities of sensor technology.
This course, which can even be taken for academic credit as part of CU Boulder’s Master of Science in Electrical Engineering, offers a comprehensive journey from theoretical understanding to hands-on implementation. The curriculum is meticulously structured, starting with the fundamentals of specifying the right sensor for real-time process data.
The syllabus dives deep into **Thermal Sensors**, explaining the theory, formulae, and commercial applications of thermistors, RTDs, and thermocouples. It covers everything from common sensor types in everyday devices like smartphones to the nuances of analog and digital interfaces. What truly impressed me was the practical guidance on how to purchase these components, making the transition from learning to doing seamless.
Moving into **Sensor Development Kit and Prototyping**, the course provides a fantastic opportunity to design a complete temperature sensor system within a development kit. You’ll learn to assign internal components, wire external parts like thermistors, and crucially, interface them to a microprocessor-based development kit using both schematic design and C programming. This hands-on approach solidifies the theoretical knowledge gained in the first module.
The course doesn’t stop at thermal sensors. **Rotary and Flow Sensors** are explored in detail, covering optical encoders, resolvers, and a wide array of flow meter technologies like ultrasonic, thermal mass flow, and Coriolis. This breadth of coverage ensures a well-rounded understanding of different sensing modalities.
Furthermore, the module on **Amplifiers and Sensor Noise** is critical for anyone serious about accurate sensor readings. It covers the theory and practical application of various amplifier types, including instrumentation amplifiers, and addresses the crucial topic of noise reduction in sensor circuits. Understanding how to interpret commercial chip specifications and mitigate real-world noise is a skill that elevates your design capabilities significantly.
Finally, the **Course Project** provides a dedicated space to apply everything learned, specifically focusing on a thermistor lab assignment. This practical application is the perfect capstone to the course.
**Recommendation:**
“Sensors and Sensor Circuit Design” is an exceptional course for electrical engineers, embedded systems developers, hobbyists, and students. It strikes a perfect balance between theory and practice, equipping learners with the skills to not only understand but also implement sensor solutions. If you’re looking to build robust, accurate, and efficient systems that rely on real-time data, this course is a must-take.
