Cloud SCADA platforms in SCADA systems - Mini Project: Build & Apply

Building a Simple Cloud SCADA Platform Data Monitor

📖 Scenario: You are working with a cloud-based SCADA platform that monitors sensor data from a factory. The platform collects sensor readings like temperature and pressure from multiple machines. Your task is to create a simple program that stores sensor data, sets a threshold for alerts, filters sensors exceeding the threshold, and then displays the alerting sensors.

🎯 Goal: Build a small program that stores sensor readings in a dictionary, sets an alert threshold, filters sensors with readings above the threshold, and prints the alerting sensors.

📋 What You'll Learn

Create a dictionary called sensor_readings with exact sensor names and values

Create a variable called alert_threshold with the exact value 75

Use a dictionary comprehension called alert_sensors to filter sensors with readings above alert_threshold

Print the alert_sensors dictionary to display sensors exceeding the threshold

💡 Why This Matters

🌍 Real World

Cloud SCADA platforms monitor industrial machines remotely by collecting sensor data and alerting operators when values go beyond safe limits.

💼 Career

Understanding how to handle sensor data and set alert thresholds is key for roles in industrial automation, cloud monitoring, and DevOps for IoT systems.

1

Create sensor readings dictionary

Create a dictionary called sensor_readings with these exact entries: 'Machine1_Temp': 68, 'Machine2_Temp': 80, 'Machine1_Pressure': 72, 'Machine2_Pressure': 78

SCADA systems

# Create the sensor_readings dictionary with exact sensor names and values
# Your code here

Need a hint?

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

2

Set alert threshold

Create a variable called alert_threshold and set it to the integer 75

SCADA systems

sensor_readings = {'Machine1_Temp': 68, 'Machine2_Temp': 80, 'Machine1_Pressure': 72, 'Machine2_Pressure': 78}
# Set alert_threshold to 75
# Your code here

Need a hint?

Simply assign the number 75 to the variable alert_threshold.

3

Filter sensors exceeding threshold

Use a dictionary comprehension to create a dictionary called alert_sensors that contains only the sensors from sensor_readings with values greater than alert_threshold

SCADA systems

sensor_readings = {'Machine1_Temp': 68, 'Machine2_Temp': 80, 'Machine1_Pressure': 72, 'Machine2_Pressure': 78}
alert_threshold = 75
# Create alert_sensors dictionary with sensors having readings > alert_threshold
# Your code here

Need a hint?

Use {sensor: value for sensor, value in sensor_readings.items() if value > alert_threshold} to filter.

4

Display alerting sensors

Write a print statement to display the alert_sensors dictionary

SCADA systems

sensor_readings = {'Machine1_Temp': 68, 'Machine2_Temp': 80, 'Machine1_Pressure': 72, 'Machine2_Pressure': 78}
alert_threshold = 75
alert_sensors = {sensor: value for sensor, value in sensor_readings.items() if value > alert_threshold}
# Print the alert_sensors dictionary
# Your code here

Need a hint?

Use print(alert_sensors) to show the sensors exceeding the threshold.
