I have been tracking temperature, humidity, light levels, outside weather data, my deep freezer\u2019s temperature, the state of <a href=\"https:\/\/twitter.com\/mytoaster\">My Toaster<\/a>, and air quality metrics. I just recently started to think about what all of this data really means to me and if it\u2019s good data to begin with. Wouldn\u2019t it be great if I could explore my data in ThingSpeak?\u00a0 Well, I am happy to say that with the latest upgrade to ThingSpeak, you can do just that.<\/p>\n<p>We have been working with the MATLAB team at MathWorks to provide two new <a href=\"https:\/\/thingspeak.com\/apps\">ThingSpeak Apps<\/a>: <em>MATLAB Analysis<\/em> and <em>MATLAB Visualizations<\/em>. With these new built-in Apps, the ThingSpeak web service can automatically run MATLAB code. That makes it easier to gain insight into your data.<\/p>\n<p><a href=\"https:\/\/thingspeak.com\/apps\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter wp-image-1476\" src=\"https:\/\/blogs.mathworks.com\/iot\/wp-content\/blogs.dir\/15\/files\/2015\/08\/ThingSpeak_Apps.png\" alt=\"ThingSpeak MATLAB Apps\" width=\"600\" height=\"386\" \/><\/a><\/p>\n<p>With the MATLAB Analysis app, I am now able to turn my home\u2019s temperature and humidity data into dew point. Dew point is important to find out if the environment is <a href=\"https:\/\/en.wikipedia.org\/wiki\/Dew_point#Relationship_to_human_comfort\">comfortable<\/a> independent of just knowing the temperature alone. If the dew point is too high or too low, your guests may notice their glasses sweating or that they are uncomfortable.<\/p>\n<p>I am also able to clean up my sensor data and filter out bad data and write it back to a new ThingSpeak channel. From time to time, I see one of my sensors report a really high value, and I\u2019d like to have a way to fix it.<\/p>\n<p>We have provided many MATLAB code examples to get started quickly.<\/p>\n<p>Some of our analysis examples include:<\/p>\n<ul>\n<li>Calculate Average Humidity<\/li>\n<li>Calculate Dew point<\/li>\n<li>Convert Celsius to Fahrenheit<\/li>\n<li>Eliminate data outliers<\/li>\n<li>Convert Fahrenheit to Celsius<\/li>\n<li>Calculate hourly max temperature<\/li>\n<li>Replace missing values in data<\/li>\n<\/ul>\n<p>With MATLAB Visualizations, we made it way easier to chart data from multiple data fields. By selecting the \u201cWind Velocity\u201d example MATLAB Visualization, I can see a plot of the wind velocity data collected by my weather station.<\/p>\n<p><a href=\"https:\/\/thingspeak.com\/apps\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-1477\" src=\"https:\/\/blogs.mathworks.com\/iot\/wp-content\/blogs.dir\/15\/files\/2015\/08\/MATLAB_Plot_Output.png\" alt=\"MATLAB Plot Output on ThingSpeak\" width=\"375\" height=\"377\" \/><\/a><\/p>\n<p>Other visualization examples include:<\/p>\n<ul>\n<li>View temperature variation over the last 24 hours using a histogram<\/li>\n<li>Plot wind velocity over the last hour using a compass plot<\/li>\n<li>Understand relative temperature variation<\/li>\n<li>Plot data from multiple fields<\/li>\n<li>View temperature and pressure levels<\/li>\n<li>Visualize relationship between temperature and humidity<\/li>\n<\/ul>\n<p>Are you looking for an easy way to connect your Arduino or Raspberry Pi devices to ThingSpeak? We have also been working with the MATLAB team at MathWorks on some Hardware Support Packages to help with that. I\u2019ll talk about that in a future blog!<\/p>\n<p><strong>This is really big news for the ThingSpeak Community. I am really excited to see what you do with these new apps. I will share projects on the blog as they come in. Let\u2019s find out together what all of this data means.
