ITPEC IP October 2023 Question 13
ITPEC IP October 2023 — Question 13 of 100
A is a sensor and B is an actuator. The sensor measures the physical water level and converts it into data that the IoT device sends to the server. After analysis, the server returns an instruction; the actuator converts that control signal into physical action by opening or closing the sluice gate.
Answer (d)
Why not others:
- An actuator does not measure the water level; it acts on the physical environment
- A sensor does not move the gate; it observes a physical quantity
- An IoT gateway connects or translates communication among devices and networks, but neither blank represents that role because the communications module is already shown separately
Key rule: Sensor = physical world to data; actuator = control signal to physical action.
