What is a microcontroller's role in the RAWS data logger?

In the context of the RAWS (Remote Automatic Weather Station) data logger, the microcontroller plays a crucial role in processing and controlling data inputs from various sensors. This functionality is essential because the RAWS collects weather-related data through sensors that measure different atmospheric conditions, such as temperature, humidity, wind speed, and direction.

The microcontroller acts as the brain of the data logger, interpreting the electrical signals generated by these sensors. It executes programmed instructions to ensure that the data collected is accurately processed, which can involve tasks like filtering noise from the signals, calibrating sensor outputs, and managing the timing of data acquisition. Essentially, the microcontroller ensures that the raw data received from the sensors is transformed into usable information, enabling reliable weather monitoring and analysis.

While other options touch upon important aspects of a data logging system—such as data storage, conversion into user-friendly formats, and real-time display—none are primarily the function of the microcontroller. Instead, these tasks can be considered downstream processes that rely on the microcontroller's ability to first gather and process the input data from sensors.
