Trend analysis and reporting in SCADA systems - Mini Project: Build & Apply

Trend analysis and reporting

📖 Scenario: You work with a SCADA system that collects temperature readings from multiple sensors every hour. Your task is to analyze the temperature trends and generate a simple report showing average temperatures per sensor.

🎯 Goal: Build a small program that stores hourly temperature data for sensors, configures a threshold for reporting, calculates average temperatures per sensor, and prints a summary report.

📋 What You'll Learn

Create a dictionary with sensor names as keys and lists of hourly temperature readings as values

Add a threshold variable to filter sensors with average temperature above this value

Calculate the average temperature per sensor using a loop

Print a report listing sensors with average temperature above the threshold

💡 Why This Matters

🌍 Real World

SCADA systems monitor industrial sensors and analyze trends to detect anomalies or optimize processes.

💼 Career

DevOps engineers often automate data collection and reporting pipelines for monitoring system health and performance.

1

Create sensor temperature data

Create a dictionary called sensor_data with these exact entries: 'SensorA': [22.5, 23.0, 22.8], 'SensorB': [19.0, 18.5, 19.2], 'SensorC': [25.1, 24.8, 25.3]

# Create the sensor_data dictionary with exact values
# Your code here

Need a hint?

Use a dictionary with sensor names as keys and lists of floats as values.

2

Add temperature threshold

Create a variable called threshold and set it to 22.0 to filter sensors with average temperature above this value

SCADA systems

sensor_data = {
    'SensorA': [22.5, 23.0, 22.8],
    'SensorB': [19.0, 18.5, 19.2],
    'SensorC': [25.1, 24.8, 25.3]
}
# Create the threshold variable
# Your code here

Need a hint?

Just assign the number 22.0 to a variable named threshold.

3

Calculate average temperatures

Create a new dictionary called average_temps that stores the average temperature for each sensor using a for loop with variables sensor and temps iterating over sensor_data.items()

SCADA systems

sensor_data = {
    'SensorA': [22.5, 23.0, 22.8],
    'SensorB': [19.0, 18.5, 19.2],
    'SensorC': [25.1, 24.8, 25.3]
}
threshold = 22.0
# Calculate average temperatures per sensor
# Your code here

Need a hint?

Use a for loop to calculate the average by summing the list and dividing by its length.

4

Print sensors above threshold

Use a for loop with variables sensor and avg iterating over average_temps.items() to print lines like SensorA: 22.77 only if avg is greater than threshold. Use print(f"{sensor}: {avg:.2f}") to format the output.

SCADA systems

sensor_data = {
    'SensorA': [22.5, 23.0, 22.8],
    'SensorB': [19.0, 18.5, 19.2],
    'SensorC': [25.1, 24.8, 25.3]
}
threshold = 22.0
average_temps = {}
for sensor, temps in sensor_data.items():
    average_temps[sensor] = sum(temps) / len(temps)
# Print sensors with average temperature above threshold
# Your code here

Need a hint?

Loop over average_temps and print only if average is above threshold using formatted string.
