Thermal monitoring and management in Power Electronics - Mini Project: Build & Apply

Thermal Monitoring and Management

📖 Scenario: You are working on a power electronics system that needs to monitor temperature sensors and manage thermal conditions to prevent overheating.The system reads temperature values from sensors and triggers alerts if temperatures exceed safe limits.

🎯 Goal: Build a simple thermal monitoring program that stores sensor readings, sets a temperature threshold, checks which sensors exceed the threshold, and outputs the alert list.

📋 What You'll Learn

Create a dictionary with sensor names and their temperature readings

Add a temperature threshold variable

Use a loop to find sensors exceeding the threshold

Print the list of sensors that are overheating

💡 Why This Matters

🌍 Real World

Thermal monitoring is critical in power electronics to avoid damage from overheating. Systems use sensors to track temperatures and trigger cooling or shutdown.

💼 Career

Understanding how to manage sensor data and thresholds is important for roles in hardware monitoring, embedded systems, and reliability engineering.

1

Create sensor temperature data

Create a dictionary called sensor_temps with these exact entries: 'Sensor1': 45, 'Sensor2': 60, 'Sensor3': 55, 'Sensor4': 70, 'Sensor5': 50

Power Electronics

# Create the sensor_temps dictionary with exact sensor readings
# 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 temp_threshold and set it to 55

Power Electronics

sensor_temps = {'Sensor1': 45, 'Sensor2': 60, 'Sensor3': 55, 'Sensor4': 70, 'Sensor5': 50}
# Set the temperature threshold to 55
# Your code here

Need a hint?

Use a simple assignment to create the threshold variable.

3

Find sensors exceeding threshold

Create a list called alert_sensors that contains the names of sensors from sensor_temps whose temperature is greater than temp_threshold. Use a for loop with variables sensor and temp to iterate over sensor_temps.items().

Power Electronics

sensor_temps = {'Sensor1': 45, 'Sensor2': 60, 'Sensor3': 55, 'Sensor4': 70, 'Sensor5': 50}
temp_threshold = 55
alert_sensors = []
# Use a for loop with sensor and temp to find sensors exceeding temp_threshold
# Your code here

Need a hint?

Start with an empty list, then add sensor names when their temperature is above the threshold.

4

Print alert sensors

Write a print statement to display the alert_sensors list.

Power Electronics

sensor_temps = {'Sensor1': 45, 'Sensor2': 60, 'Sensor3': 55, 'Sensor4': 70, 'Sensor5': 50}
temp_threshold = 55
alert_sensors = []
for sensor, temp in sensor_temps.items():
    if temp > temp_threshold:
        alert_sensors.append(sensor)
# Print the alert_sensors list
# Your code here

Need a hint?

Use print(alert_sensors) to show the sensors that are overheating.
