6.7. Humidity Sensors

Try these first

1. 1.

   What principle do capacitive humidity sensors use?

   Hint

   Think about how materials interact with electrical energy.

2. 2.

   What do resistive humidity sensors measure?

   Hint

   Consider how certain materials react to moisture.

3. 3.

   What kind of change do capacitive humidity sensors detect?

   • Change in temperature
   • Change in dielectric constant
   • Change in pressure

   Hint

   Remember what the acronym 'CAP' stands for.

4. 4.

   True or False: Resistive humidity sensors detect humidity through changes in capacitance.

   • True
   • False

   Hint

   Think about the names of the sensors.

5. 5.

   Design a maintenance plan for a building that incorporates both capacitive and resistive humidity sensors. Detail how each sensor aids in monitoring.

   Hint

   Consider why both readings matter for overall climate management.

6. 6.

   Analyze the pros and cons of capacitive versus resistive humidity sensors in civil engineering applications.

   Hint

   Think of situations where speed and sensitivity are critical.
