Learning Objectives

This lab course deals with the underlying principles and performance characteristics of sensor development and signal conditioning circuits. Through this lab course, students will get practical exposure into the different techniques involved in designing interfacing circuits for sensors. From an application perspective, this course will provide a hands­on insight into the measurement of some of the physical parameters such as displacement, moisture, temperature, liquid level etc.

Learning Outcomes

  • Understand the principle of operation and experimental exposure to different types of sensors.
  • Practical realization of the interfacing circuits and digitizer for these sensors.
  • Analyse, formulate and select the right sensor for a given application.
  • Develop and evaluate measurement systems for industrial and scientific applications.
