Plotting data from Arduino (with Multiples Sensors -Analogs and Digital-) in real time...

Hi, I am developing a project with arduino with multiples sensors analogs and digital (barometer, accelerometer, gps and lux). I need plot all data retrieved from these sensors. Please, are there an example to plot the data in real time? Thks!

Hi,

Have you tried doing this in the external mode configuration? Just connect the port to the scope. You can visualize the waveform. However, I am not sure if it is possible for GPS.

You can also use the serial communication to send all the data to Maltab and plot it:

Following are two possible ways of achieving this :

1. Using MATLAB Support Package for Arduino Hardware

Refer this link for a detailed explanation and sample code : https://in.mathworks.com/videos/plotting-live-data-of-a-temperature-sensor-using-arduino-and-matlab-121317.html

2. Using Simulink Support Package for Arduino Hardware

Here, use external mode to plot real time sensor data in Simulink scope block.
