Rule engine for IoT data routing in IOT Protocols - Mini Project: Build & Apply

Rule engine for IoT data routing

📖 Scenario: You are managing a smart home system where multiple IoT sensors send data. You want to create a simple rule engine that routes sensor data to different actions based on sensor type and value.

🎯 Goal: Build a basic rule engine that reads sensor data, applies routing rules, and outputs the action to take for each sensor reading.

📋 What You'll Learn

Create a dictionary with sensor data entries

Add a configuration variable for a threshold value

Write a loop that applies routing rules based on sensor type and threshold

Print the routing decisions for each sensor

💡 Why This Matters

🌍 Real World

IoT devices send data continuously. A rule engine helps decide what actions to take automatically, like turning on air conditioning or sending alerts.

💼 Career

Understanding how to route IoT data with simple rules is useful for roles in IoT development, DevOps automation, and smart system management.

1

Create sensor data dictionary

Create a dictionary called sensor_data with these exact entries: 'temperature': 22, 'humidity': 55, 'motion': 1

IOT Protocols

# Create the sensor_data dictionary with given entries
# Your code here

Need a hint?

Use curly braces to create a dictionary with keys and values separated by colons.

2

Add threshold configuration

Create a variable called temp_threshold and set it to 25 to use as the temperature threshold.

IOT Protocols

sensor_data = {'temperature': 22, 'humidity': 55, 'motion': 1}
# Create temp_threshold variable and set to 25
# Your code here

Need a hint?

Just assign the number 25 to the variable named temp_threshold.

3

Apply routing rules

Write a for loop using variables sensor and value to iterate over sensor_data.items(). Inside the loop, create a variable action and set it to 'Turn on AC' if sensor is 'temperature' and value is greater than temp_threshold. Otherwise, set action to 'No action'.

IOT Protocols

sensor_data = {'temperature': 22, 'humidity': 55, 'motion': 1}
temp_threshold = 25
# Write a for loop to apply routing rules
# Your code here

Need a hint?

Use an if-else statement inside the loop to decide the action based on sensor type and value.

4

Print routing decisions

Inside the existing for loop, add a print statement that outputs the text "Sensor: {sensor}, Value: {value}, Action: {action}" using an f-string.

IOT Protocols

sensor_data = {'temperature': 22, 'humidity': 55, 'motion': 1}
temp_threshold = 25
for sensor, value in sensor_data.items():
    if sensor == 'temperature' and value > temp_threshold:
        action = 'Turn on AC'
    else:
        action = 'No action'
    # Print the routing decision
    # Your code here

Need a hint?

Use print(f"Sensor: {sensor}, Value: {value}, Action: {action}") inside the loop to show the routing results.
