In a typical IoT architecture, which layer is mainly responsible for sensing the physical environment and collecting raw data, such as temperature or motion?
The perception, or device, layer does the sensing. It contains sensors and actuators that detect physical conditions like temperature or motion and gather raw data, which higher layers then transmit, process and present to users through applications.
- AApplication layer
- BPerception (device) layerCorrect
- CBusiness layer
- DCloud analytics layer
Explanation
The perception or device layer contains sensors and actuators that detect physical parameters and gather raw data. The application layer delivers services to users, and analytics happens higher up. Hence the perception layer is correct.
