6.1. Classification of Sensors

Try these first

1. 1.

   What is a displacement sensor used for?

   Hint

   Think about how things change position.

2. 2.

   Give one example of a passive sensor.

   Hint

   Consider sensors that don't need power.

3. 3.

   What type of sensor measures structural vibrations?

   • Load Sensor
   • Vibration Sensor
   • Humidity Sensor

   Hint

   Think about what sensor captures movement.

4. 4.

   True or False? Passive sensors require an external power source.

   • True
   • False

   Hint

   Consider how they work.

5. 5.

   If you were designing a sensor network for a new bridge, what consideration would you prioritize in your choice of sensors based on their working principle?

   Hint

   Think about the bridge's environment and the data needed.

6. 6.

   Create a scenario where using an active sensor would be more beneficial than a passive sensor in a civil engineering application.

   Hint

   Why might a sensor need to be powered during strong activities?
