Training Sensors & Measurement

Sensors & Measurement

Math in Action
Exploratory 30 minutes 2 lessons
Learn how every sensor in the modern world — from thermistors to GPS satellites — converts physical quantities into numbers using transfer functions, logarithms, and signal processing.

Learning Objectives

  • Understand sensor transfer functions (linear, logarithmic, exponential)
  • See how GPS uses algebra and the speed of light to find your location
  • Explore how accelerometers in your phone use Newton's second law
  • Appreciate signal-to-noise ratios and the decibel scale
