3.2.1. Types of Physical Quantities Sensed

Try these first

1. 1.

   What do we call the measurement of how hot or cold something is?

   Hint

   Think about how a thermometer works.

2. 2.

   What does a pressure sensor measure?

   Hint

   Consider where you find such sensors often.

3. 3.

   What type of sensor measures displacement?

   • Accelerometer
   • Thermal sensor
   • Pressure sensor

   Hint

   Consider what device helps detect movements in your smartphone.

4. 4.

   True or False: A temperature sensor measures heat flux.

   • True
   • False

   Hint

   Remember the distinction between static and dynamic thermal quantities.

5. 5.

   Describe an experiment using MEMS sensors for environmental monitoring. Which quantities would you measure and why?

   Hint

   Think about measuring changes in air quality over time.

6. 6.

   Analyze how strain sensing might impact the design of a bridge.

   Hint

   Consider safety standards in engineering.
