What is the primary role of MQTT in publishing sensor data from a Raspberry Pi?

ATo store sensor data locally on the Raspberry Pi
BTo send sensor data to a broker for distribution
CTo process sensor data and display it on the Pi screen
DTo convert sensor data into images
Step-by-Step Solution
Solution:

  1. Step 1: Understand MQTT's role

    MQTT is a messaging protocol designed to send data from devices to a central broker.

  2. Step 2: Identify the correct function in sensor data publishing

    Publishing means sending data to the broker, not storing or processing locally.

  3. Final Answer:

    To send sensor data to a broker for distribution -> Option B

  4. Quick Check:

    MQTT role = Send data [OK]
Quick Trick: MQTT sends data to a broker, not stores it locally [OK]
Common Mistakes:
MISTAKES
  • Confusing publishing with storing data
  • Thinking MQTT processes data on the Pi
  • Assuming MQTT converts data to images
