Webhook for IoT events in IOT Protocols - Mini Project: Build & Apply

Webhook for IoT events

📖 Scenario: You are managing a smart home system where various IoT devices send event data like temperature readings and motion detection alerts. You want to create a webhook that receives these events and processes them.

🎯 Goal: Build a simple webhook handler that stores incoming IoT event data, configures a filter for important events, processes only those events, and finally outputs the filtered events.

📋 What You'll Learn

Create a dictionary called iot_events with exact event entries

Add a configuration variable called threshold_temperature with value 25

Use a dictionary comprehension to filter events where temperature is above threshold_temperature

Print the filtered events dictionary

💡 Why This Matters

🌍 Real World

IoT devices often send data to servers via webhooks. Filtering this data helps focus on important events like high temperatures or security alerts.

💼 Career

Understanding how to handle webhook data and filter events is key for roles in IoT development, DevOps, and cloud infrastructure management.

1

Create initial IoT event data

Create a dictionary called iot_events with these exact entries: 'sensor1': 22, 'sensor2': 27, 'sensor3': 24, 'sensor4': 30

IOT Protocols

# Create the iot_events dictionary with sensor readings
# Your code here

Need a hint?

Use curly braces to create a dictionary with keys as sensor names and values as their temperature readings.

2

Add temperature threshold configuration

Add a variable called threshold_temperature and set it to 25

IOT Protocols

iot_events = {'sensor1': 22, 'sensor2': 27, 'sensor3': 24, 'sensor4': 30}
# Add threshold_temperature variable
# Your code here

Need a hint?

Just create a variable and assign the number 25 to it.

3

Filter events above threshold

Use a dictionary comprehension to create a new dictionary called filtered_events that includes only sensors from iot_events with values greater than threshold_temperature

IOT Protocols

iot_events = {'sensor1': 22, 'sensor2': 27, 'sensor3': 24, 'sensor4': 30}
threshold_temperature = 25
# Create filtered_events dictionary using comprehension
# Your code here

Need a hint?

Use {key: value for key, value in dict.items() if condition} syntax to filter.

4

Print filtered events

Write a print statement to display the filtered_events dictionary

IOT Protocols

iot_events = {'sensor1': 22, 'sensor2': 27, 'sensor3': 24, 'sensor4': 30}
threshold_temperature = 25
filtered_events = {sensor: temp for sensor, temp in iot_events.items() if temp > threshold_temperature}
# Print the filtered_events dictionary
# Your code here

Need a hint?

Use print(filtered_events) to show the filtered dictionary.
