12.4.1. Example Scenario

Try these first

1. 1.

   What function is used to initialize the sensor?

   Hint

   Think about how we prepare the sensor.

2. 2.

   Why is data processing necessary?

   Hint

   Consider the need for accuracy before output.

3. 3.

   What is the purpose of the sensor_init() function?

   • To read data from the sensor
   • To initialize the sensor
   • To process the sensor data

   Hint

   Think about what setup is needed before using the sensor.

4. 4.

   True or false: Data processing is not necessary before displaying sensor data.

   • True
   • False

   Hint

   Reflect on the importance of clarity and accuracy in outputs.

5. 5.

   You need to create a humidity sensor application that continuously monitors humidity levels and activates a fan when the level exceeds a threshold. Describe key modifications from the temperature example.

   Hint

   Consider which parts of the temperature example are applicable and where new components are needed.

6. 6.

   Discuss how you would implement error handling for sensor reading failures within the given structure.

   Hint

   Think about how to ensure your application remains user-friendly even when errors occur.
