6.7.2. Resistive Humidity Sensors

Try these first

1. 1.

   What principle do resistive humidity sensors operate on?

   Hint

   Think about how materials react to moisture.

2. 2.

   Give one application of resistive humidity sensors.

   Hint

   Consider where humidity needs to be managed.

3. 3.

   What is the main function of resistive humidity sensors?

   • To measure temperature
   • To measure humidity
   • To detect pressure

   Hint

   What does a humidity sensor track?

4. 4.

   True or False: Resistance increases as moisture levels increase in hygroscopic materials.

   • True
   • False

   Hint

   Recall the relationship between moisture and resistance.

5. 5.

   A city council is considering upgrading its underground metro system with resistive humidity sensors. What are the potential challenges they may face during installation?

   Hint

   Think about practical issues during installation.

6. 6.

   If a resistive humidity sensor indicates a sudden drop in resistance, what could this imply about the monitored environment? Analyze the situation.

   Hint

   Recall what the changes in resistance signify.
