This model provides a functional allocation for a weather system known as a Stevenson Screen. Such a weather enclosure contains and protects instrumentation used to measure temperature, humidity, barometric pressure and records specialized derivatives of these measurements.
A barometer, hygrometer, thermometer, psychrometer and dewcell measure physical factors in the environment. A thermograph records temperature and humidity. Each of these deliver their acquired data through a concentrator to an internet host.
The first diagram show the “parts” of the system abstracted as UML components. The second diagram illustrates a deployment configuration of the components interconnected across their interfaces.
The system uses an interface based upon MQ Telemetry Transport (MQTT) message brokering.
The host stores recordings in a cloud data base. This is a nice example of the Internet of Things.
