Scenario & Sequence Diagram

Scenario 1

The lamp will be turn on when there is no light or light intensity goes down below visibility or turn off when there is sufficient light with the condition that the home owner is at home.

• i. Sensors: light detection sensor, identity sensor
• ii. Actuators: electricity supply regulator
• iii. Device (Object): lamp

It is worth noting that the below sequence diagram for scenario 1 is based on the IOTs system modelling in https://doc.info.fundp.ac.be/mediawiki/index.php/IoT-infrastructure-modelling

Scenario 2

User requests to turn-on or turn-off light or other devices through client application.

• ii. Actuators: electricity supply regulator
• iii. Device (Object): lamp (other devices)

It is worth noting that the below sequence diagram for scenario 1 is based on the IOTs system modelling in https://doc.info.fundp.ac.be/mediawiki/index.php/IoT-infrastructure-modelling

Scenario 3

When movement sensor detects moving object, the CCTV is turn-on and the alarm message is sent to user through client application.

• i. Sensors: movement sensor
• ii. Actuators: electricity supply regulator
• iii. Device (Object): CCTV

Scenario 4

When smoke sensor detects smoke and the temperature sensor detects unusual temperature raised, the alarm message is sent to user through client application.

• i. Sensors: smoke detector and temperature sensor
