Why data acquisition captures real-world measurements in SCADA systems - See It in Action

Why Data Acquisition Captures Real-World Measurements

📖 Scenario: You are working with a SCADA system that monitors a factory's temperature sensors. The system collects real-world temperature data to help operators keep machines running safely.

🎯 Goal: Build a simple program that stores sensor readings, sets a threshold, filters readings above the threshold, and displays them. This shows how data acquisition captures and uses real-world measurements.

📋 What You'll Learn

Create a dictionary called sensor_readings with exact temperature values from sensors

Add a variable called threshold to set the temperature limit

Use a dictionary comprehension to create high_temps with readings above the threshold

Print the high_temps dictionary to show filtered sensor data

💡 Why This Matters

🌍 Real World

SCADA systems collect real-world measurements from sensors to monitor and control industrial processes safely and efficiently.

💼 Career

Understanding how to capture and filter sensor data is essential for roles in industrial automation, system monitoring, and DevOps for infrastructure that relies on real-time data.

1

Create sensor readings dictionary

Create a dictionary called sensor_readings with these exact entries: 'sensor1': 72, 'sensor2': 85, 'sensor3': 78, 'sensor4': 90, 'sensor5': 69

SCADA systems

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

Need a hint?

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

2

Set temperature threshold

Add a variable called threshold and set it to 75 to represent the temperature limit

SCADA systems

sensor_readings = {'sensor1': 72, 'sensor2': 85, 'sensor3': 78, 'sensor4': 90, 'sensor5': 69}
# Set the threshold variable to 75
# Your code here

Need a hint?

Just create a variable named threshold and assign it the value 75.

3

Filter readings above threshold

Use a dictionary comprehension to create a new dictionary called high_temps that includes only sensors with readings greater than threshold. Use sensor and temp as the loop variables.

SCADA systems

sensor_readings = {'sensor1': 72, 'sensor2': 85, 'sensor3': 78, 'sensor4': 90, 'sensor5': 69}
threshold = 75
# Create high_temps dictionary with sensors having temp > threshold
# Your code here

Need a hint?

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

4

Display filtered sensor readings

Write a print statement to display the high_temps dictionary

SCADA systems

sensor_readings = {'sensor1': 72, 'sensor2': 85, 'sensor3': 78, 'sensor4': 90, 'sensor5': 69}
threshold = 75
high_temps = {sensor: temp for sensor, temp in sensor_readings.items() if temp > threshold}
# Print the high_temps dictionary
# Your code here

Need a hint?

Use print(high_temps) to show the filtered dictionary.
