Rule engine for IoT data routing in IOT Protocols - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a rule that routes temperature data to the cooling system.

IOT Protocols

rule = {"condition": "data.type == '[1]'", "action": "send_to_cooling()"}

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

💡 Hint

Common Mistakes

Using 'humidity' or other data types instead of 'temperature'.

The rule checks if the data type is 'temperature' to trigger cooling.

2fill in blank

medium

Complete the code to route data with value above 75 to the alert system.

IOT Protocols

rule = {"condition": "data.value [1] 75", "action": "send_alert()"}

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

A<

B>

C==

D<=

💡 Hint

Common Mistakes

Using '<' or '==' which do not check for values above 75.

The rule triggers an alert when the data value is greater than 75.

3fill in blank

hard

Fix the error in the rule condition to correctly check if data.status equals 'active'.

IOT Protocols

rule = {"condition": "data.status [1] 'active'", "action": "process_active()"}

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

A=

B!=

C==

D=>

💡 Hint

Common Mistakes

Using '=' which assigns instead of compares.

Using '=>' which is invalid here.

The correct equality operator in conditions is '=='.

4fill in blank

hard

Fill both blanks to create a rule that routes data with type 'humidity' and value less than 30 to the dehumidifier.

IOT Protocols

rule = {"condition": "data.type == '[1]' and data.value [2] 30", "action": "activate_dehumidifier()"}

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

Ahumidity

B>

C<

Dtemperature

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'temperature' instead of 'humidity'.

Using '>' instead of '<' for value comparison.

The rule checks if data type is 'humidity' and value is less than 30 to activate the dehumidifier.

5fill in blank

hard

Fill all three blanks to define a rule that routes data with type 'pressure', value greater than 100, and status 'critical' to the emergency system.

IOT Protocols

rule = {"condition": "data.type == '[1]' and data.value [2] 100 and data.status == '[3]'", "action": "trigger_emergency()"}

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

B>

Ccritical

Dpressure

Attempts:

3 left

💡 Hint

Common Mistakes

Using wrong data type like 'temperature'.

Using '<' instead of '>' for value.

Using wrong status value.

The rule activates emergency when data type is 'pressure', value is greater than 100, and status is 'critical'.
