Signals and Sensors

In this lab, students will learn about various sensors, when to use them and their characteristics. Students will learn about the various signals that are used to measure the sensors. There are three activities in this lab, first students will investigate an IR sensor by taking measurements. Second, students will be given temperature and strain measurement scenario with specifications and several sensor choices. Based on the specification, students decide which sensor is best suited for the application.

This is lab 1 of 9 in the course, Measurements and Instrumentation.


After completing this lab, students will be able to:
  1. Discuss the purpose of a sensor and the different types and characteristics.
  2. Discuss the characteristics of a signal and how they relate to the physical world
  3. Analyze a spec sheet and choose an appropriate sensor based on a measurement need.
