Answer Key

Smart objects and the Internet of Things

Section A: Quick Questions

B — A smart thermostat that senses room temperature and connects to Wi-Fi

B — Collects and shares it over a network so it can act on it

A — A motion sensor

A — A network connection such as Wi-Fi or Bluetooth

A — It alerts your phone about a fire even when you are away from home

Section B: Match the Pairs

smartThermostat.readSensor("temperature") → A smart home device uses a sensor to collect data about the room so the system can act on it

smartLight.connect("home_wifi") → The object joins a network so it can share data and receive commands over the internet

An IoT object acts on the data it collects, such as turning on the heating when a room is cold → if temperature < 18: heater.turnOn()

Data from an IoT object should be protected so that unauthorised people cannot access it → camera.setPassword(strongPassword)

smartDoorbell = "a normal doorbell with no network or sensors" → This is not an IoT object because it has no sensors and no connection to a network, so it cannot collect or share data.

smartSpeaker.sendAudioToServer() # no user consent asked → The device shares recordings without asking the user, which is a privacy concern.

Section C: Definitions

Internet of Things (IoT) — A network of everyday objects with sensors and software that connect to the internet so they can collect and share data and act on it, such as smart lights or thermostats.

Section D: Fill in the Blanks

temp = sensor.read()

IF temp > 25 THEN
  fan.turn_on()
END IF

network.send(temp)

camera.encrypt(video)

IF door.locked = FALSE THEN alert(phone)

Section E: Spot the Error

C — A single = assigns a value. A condition needs == to compare the sensor reading with True. It should be: if motion == True:

C — The heater should switch on when the room is colder than the target, not hotter. The condition should be: if temp < target:

D — The variable is misspelled. The sensor value is stored in reading, so readng does not exist. It should be: wifi.send(reading)

A — A while statement must end with a colon. It should be: while True:

D — The closing bracket is missing, so the function call is incomplete. It should be: cloud.upload(data)
