Creating a real-time data acquisition system involves integrating hardware and software components to collect, process, and visualize data instantly. Using Simulink and Arduino provides an accessible platform for developing such systems, suitable for educational and industrial applications.
Components Needed
- Arduino microcontroller
- Sensors (e.g., temperature, humidity)
- USB cable for connection
- Simulink software
- Power supply
Setting Up Arduino
Connect sensors to the Arduino pins according to the sensor specifications. Upload the Arduino sketch that enables serial communication and reads sensor data. Ensure the Arduino is recognized by the computer.
Configuring Simulink
Open Simulink and install the Arduino Support Package if not already installed. Create a new model and add the Arduino I/O blocks to establish communication. Configure the blocks to match the Arduino pins used for sensors.
Building the Data Flow
Design the Simulink model to read data from Arduino, process it if necessary, and display it in real-time. Use scope blocks or dashboards for visualization. Set the sample time to ensure data updates at desired intervals.
