Publishing sensor data in IOT Protocols - Mini Project: Build & Apply

Publishing sensor data

📖 Scenario: You have a small temperature sensor device that collects temperature readings every minute. You want to send these readings to a central server using a simple IoT protocol.

🎯 Goal: Build a small program that prepares temperature data and publishes it using a simulated IoT protocol message format.

📋 What You'll Learn

Create a dictionary with sensor data readings

Add a configuration variable for the sensor ID

Format the data into a publishable message string

Print the final message to simulate sending

💡 Why This Matters

🌍 Real World

IoT devices often collect sensor data and send it to servers for monitoring and analysis. Preparing and publishing data in a clear format is essential.

💼 Career

Understanding how to structure and send sensor data is a key skill for IoT developers and DevOps engineers working with connected devices.

1

Create sensor data dictionary

Create a dictionary called sensor_data with these exact entries: 'temperature': 22.5, 'humidity': 45, 'pressure': 1013

IOT Protocols

# Create the sensor_data dictionary with temperature, humidity, and pressure
# Your code here

Need a hint?

Use curly braces to create a dictionary with the exact keys and values.

2

Add sensor ID configuration

Create a variable called sensor_id and set it to the string 'sensor_001'

IOT Protocols

sensor_data = {'temperature': 22.5, 'humidity': 45, 'pressure': 1013}
# Create the sensor_id variable with value 'sensor_001'
# Your code here

Need a hint?

Assign the string 'sensor_001' to the variable sensor_id.

3

Format publish message

Create a variable called publish_message that formats the string as "ID: sensor_001, Data: {'temperature': 22.5, 'humidity': 45, 'pressure': 1013}" using an f-string with sensor_id and sensor_data

IOT Protocols

sensor_data = {'temperature': 22.5, 'humidity': 45, 'pressure': 1013}
sensor_id = 'sensor_001'
# Create publish_message using f-string with sensor_id and sensor_data
# Your code here

Need a hint?

Use an f-string to insert sensor_id and sensor_data into the message string.

4

Print the publish message

Write a print statement to display the publish_message variable

IOT Protocols

sensor_data = {'temperature': 22.5, 'humidity': 45, 'pressure': 1013}
sensor_id = 'sensor_001'
publish_message = f"ID: {sensor_id}, Data: {sensor_data}"
# Print the publish_message
# Your code here

Need a hint?

Use print() to show the publish_message on the screen.
