Thermal monitoring and management in Power Electronics - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to read the temperature sensor value.

Power Electronics

temperature = sensor.read_temperature([1])

Drag options to blanks, or click blank then click option'

CKelvin

DResistance

💡 Hint

Common Mistakes

Using voltage or resistance instead of temperature units.

The sensor.read_temperature function requires the unit of measurement. Using 'Celsius' returns the temperature in degrees Celsius.

2fill in blank

medium

Complete the code to trigger a cooling fan when temperature exceeds threshold.

Power Electronics

if temperature [1] threshold:
    fan.turn_on()

Drag options to blanks, or click blank then click option'

A<

B==

C<=

D>

Attempts:

💡 Hint

Common Mistakes

Using less than operator which triggers fan at low temperature.

The fan should turn on when the temperature is greater than the threshold to cool the system.

3fill in blank

hard

Fix the error in the code to log temperature readings every 5 seconds.

Power Electronics

while True:
    log.write(temperature)
    time.sleep([1])

Drag options to blanks, or click blank then click option'

C1

D0

💡 Hint

Common Mistakes

Using 0 causes continuous logging without delay.

To log every 5 seconds, the sleep duration must be 5 seconds.

4fill in blank

hard

Fill both blanks to create a dictionary of sensor names and their temperature values above threshold.

Power Electronics

high_temps = {sensor[1]: temp for sensor, temp in readings.items() if temp [2] threshold }

Drag options to blanks, or click blank then click option'

A.name

B<

C>

D_id

Attempts:

3 left

💡 Hint

Common Mistakes

Using '<' filters low temperatures instead of high.

Use sensor.name to get the sensor's name and filter temperatures greater than the threshold.

5fill in blank

hard

Fill all three blanks to create a filtered dictionary with uppercase sensor names and temperatures below threshold.

Power Electronics

filtered = { [1]: [2] for sensor, temp in data.items() if temp [3] threshold }

Drag options to blanks, or click blank then click option'

Asensor.name.upper()

Btemp

C<

Dsensor.id

Attempts:

3 left

💡 Hint

Common Mistakes

Using sensor.id instead of name, or wrong comparison operator.

Use sensor.name.upper() for uppercase keys, temp as values, and filter temps less than threshold.
