Edge gateway architecture in IOT Protocols - Mini Project: Build & Apply

Edge Gateway Architecture Setup

📖 Scenario: You are working on an IoT project where multiple sensors send data to an edge gateway. The edge gateway collects this data, filters it, and then forwards only important information to the cloud. This helps reduce network traffic and speeds up response times.

🎯 Goal: Build a simple edge gateway data processor that stores sensor readings, sets a threshold to filter important data, filters the data based on this threshold, and finally outputs the filtered data ready to be sent to the cloud.

📋 What You'll Learn

Create a dictionary called sensor_data with exact sensor names and their readings

Add a variable called threshold with the exact value 50

Use a dictionary comprehension called filtered_data to keep only sensors with readings above the threshold

Print the filtered_data dictionary to show the filtered sensor readings

💡 Why This Matters

🌍 Real World

Edge gateways collect and filter data from many IoT sensors before sending only important information to the cloud. This reduces network load and speeds up decision-making.

💼 Career

Understanding edge gateway data filtering is key for IoT engineers and DevOps professionals working with distributed sensor networks and cloud integration.

1

Create initial sensor data dictionary

Create a dictionary called sensor_data with these exact entries: 'temp_sensor': 45, 'humidity_sensor': 55, 'pressure_sensor': 48, 'light_sensor': 60

IOT Protocols

# Create the sensor_data dictionary with exact sensor readings
# Your code here

Need a hint?

Use curly braces {} to create the dictionary and separate each sensor and reading with a comma.

2

Add threshold value

Add a variable called threshold and set it to the integer value 50

IOT Protocols

sensor_data = {'temp_sensor': 45, 'humidity_sensor': 55, 'pressure_sensor': 48, 'light_sensor': 60}
# Add the threshold variable below
# Your code here

Need a hint?

Just write threshold = 50 on a new line.

3

Filter sensor data using threshold

Use a dictionary comprehension to create a new dictionary called filtered_data that includes only sensors from sensor_data with readings greater than threshold

IOT Protocols

sensor_data = {'temp_sensor': 45, 'humidity_sensor': 55, 'pressure_sensor': 48, 'light_sensor': 60}
threshold = 50
# Create filtered_data dictionary using dictionary comprehension
# Your code here

Need a hint?

Use {sensor: reading for sensor, reading in sensor_data.items() if reading > threshold} to filter.

4

Print filtered sensor data

Write a print statement to display the filtered_data dictionary

IOT Protocols

sensor_data = {'temp_sensor': 45, 'humidity_sensor': 55, 'pressure_sensor': 48, 'light_sensor': 60}
threshold = 50
filtered_data = {sensor: reading for sensor, reading in sensor_data.items() if reading > threshold}
# Print the filtered_data dictionary
# Your code here

Need a hint?

Use print(filtered_data) to show the filtered sensors.
