Schedule MATLAB Code with TimeControl

Posted by Hans Scharler,

Here at our headquarters we have a weather station collecting lots of weather data and sending it to ThingSpeak. We have made that data public for use in your own projects.

We write the temperature and humidity values from the weather station to a ThingSpeak channel. At some point in the project, we started… read more >>

Updates to the MATLAB Analysis App with Lots of Example Code

Posted by Hans Scharler,

When using the MATLAB Analysis app on ThingSpeak, the MATLAB function to represent date and time (datetime) allows you to represent points in time. You can also use datetime(‘now’),  datetime(‘today’), datetime(‘yesterday’), or datetime(‘tomorrow’) to create scalar datetimes at or around the current moment. Check out our documentation for more information… read more >>

You’ve Collected Lots of IoT Data, Now We Can Help You Figure Out What It Means! 2

Posted by Hans Scharler,

For the last several years, I have been collecting data with ThingSpeak from devices all around my house. I have been tracking temperature, humidity, light levels, outside weather data, my deep freezer’s temperature, the state of My Toaster, and air quality metrics. I just recently started to think about what… read more >>
