Simulink Model For Real-Time Logging Of Process Data In MATLAB Workspace

This project establishes a real-time data acquisition pipeline connecting a physical Arduino Uno hardware setup to a host computer running MATLAB and Simulink. At the heart of the hardware circuit is the LM35 precision IC temperature sensor, which measures ambient temperature and outputs a linear analog voltage proportional to the Celsius temperature. This analog signal is wired directly into one of the analog input pins on the Arduino Uno development board. Using the Legacy MATLAB and Simulink Support for Arduino package, the Simulink environment communicates directly with the Arduino Uno over a USB serial connection. Inside Simulink, an IO library block reads the voltage value from the specified analog pin at a designated sample rate. The model processes this incoming raw voltage, scales it appropriately to represent accurate temperature units, and routes the data directly into the MATLAB workspace. Once logged in the workspace, engineers can visualize the thermal dynamics instantly, plot the time-series data, or save the dataset for advanced post-processing and analysis without needing to manually write complex serial-reading scripts in the Arduino IDE.
