Using the technique of Noun Analysis, analyse the following scenario and develop a conceptual domain model, using a UML class diagram to represent the high-level domain concepts. Ensure you represent all identified associations and constraints within the model. b) You have been tasked with designing the software system for a simple weather station. Currently the system keeps track of temperature but must be flexible enough to be expanded at a later stage. The system is composed of a basic Micro-controller, a single temperature sensor, a display, memory bank and user buttons. The system displays temperature readings in real time on the display. It also keeps track of historical information on an hourly and daily basis. This historical data can be pulled up on the display at the request of the user by pressing the appropriate button.

In your answer mention how callback functions maybe (10 marks) used to realse a state machine within C++
