If you are a student or researcher looking for a project idea, have a look at the MathWorks Excellence in Innovation site. There is at least one IoT-based project for a Smart watering system, and a project with a Digital twin of a pneumatic system. If you ask me, most of the other projects could also be enhanced with an IoT based component shared on ThingSpeak!
My dear friend Ram and I have finished our latest movie series. You can watch the final movie , or see the whole series.
In this movie we show how you can use TimeControls and Reacts to control devices or to schedule your MATLAB code that you can write in ThingSpeak. We also discuss a bit about channel sharing.
The third movie in our new series is live. We focus on MATLAB Analysis and Visualizations in this video. You can see how to set up code to preprocess your data and how to add custom visualizations.
We've started a new video series on how and why to use ThingSpeak. IoT from Data to Action . Most of you pros here at the forum probably already know this stuff, but there's some great overview material in these videos if you are interested. Two of four planned movies are posted, Ill let you know again when the others come out too. -Christopher
I recently found some interesting hardware in a demo on Hackster. The Magicbit is an ESP32-based project platform. It includes some plug and play sensors and a built-in display on a brightly colored PCB. The demo shows how to send the data collected by the Magicbit to ThingSpeak. You can see how to use the Arduino IDE to program the device, using the ThingSpeak library for Arduino, ESP 8266, and ESP32 . Of course, once you get the data into ThingSpeak, you can use the integrated MATLAB to do just about anything with the data. The Magicbit is funded from a Kickstarter campaign .

Are you using ESP32 and want to help us develop functionality for it? We are looking to add support for ESP32 boards in MATLAB. If you have experience with ESP32 and care to share your workflows with us, please let me know here and we will reach out to you for a short interview.
ThingSpeak includes an integration with The Things Stack to support collection of data over a long range network. I made a short presentation for this upcoming conference that shows you how to add the ThingSpeak integration to your Things Stack project. The agenda seems to be filled with other useful IoT talks. Here is the information on the conference:
Discover the next-generation #LoRaWAN deployments at The Things Stack Conference. Explore advanced LoRaWAN features, cloud integrations and the next-generation #IoT devices at #TheThingsConference - TheThings Stack Edition, online on 28 May 2021!

I've been working with several collaborators on an indoor air quality monitoring project. You can see the post at Hackster . It would be interesting to deploy many of these throughout a building to investigate interactions between different rooms and the flow of people. So far I've got two in my house. Let us know if you plan to make a few of them.
I'm presently working on an Air Quality monitor to be able to check the status of my environment and remote environments on ThingSpeak. I was planning on using the BME680 sensor. Does anyone have any experience with this or other air quality sensors? I'm looking probably for CO2 and the like (Volatile Organics), not so much particle sensors, though a combination may be best.
Right now ThingSpeak supports up to 8 fields of data plus the status and three position fields. If you could have more fields, how many would you want? I have one channel of control settings for a project that I would have used up to 12, but no more than that.
Did you know you can change your user id? We went through a short time where everyone was auto assigned a long user id with 'mwa' and a bunch of numbers that couldn't be changed. You can now make it something more relevant to your actual IoT persona. Click on your user picture or icon on the upper right. Select 'My Profile' and click the Edit button under username.

One great thing about IoT projects is they are connected to the internet, and that creates an opportunity to collaborate at a distance. Here are resources to help you teach classes that involve remote learning.
- Record and visualize your experiment's data in ThingSpeak channels. For example, this public soil monitor channel shows measurements from a sensor connected to a plant. You can see the ThingSpeak example pages for help getting your experiment connected.
- If you don’t have your own equipment see one of our 1,000,000 existing channels. Check out over 200,000 public channels at ThingSpeak.com.
- Use the fitvirus program to fit COVID-19 data. You can download the fitvirus code on File Exchange. You can get your own data or download statistics from a public ThingSpeak channel with COVID-19 data. For other COVID-19 related resources see COVID-19 Research and Development with MATLAB and Simulink
Figure 1: Fitvirus sample results.
When you can’t make it into the lab, use ThingSpeak to monitor and control your lab equipment for experiments and for teaching.
- When you use ThingSpeak channel values to control your hardware modes, students can run experiments from home, and even collaborate with others to control devices and collect data for analysis.
Figure 2: Sample ThingSpeak lab model.
- Build a simulation model to deploy on hardware and control it remotely. Watch this video to see how you can do both simulation and deployment in the same Simulink model. You can also download the models used in the video.
- Use ThingSpeak to analyze your data. Use the provided code templates (like this one for removing outliers from wind speed data) or custom MATLAB code to filter and analyze your data and schedule it to run at regular intervals.
regularFlag = isregular(data,'Time')
- Use ThingSpeak to Visualize your data. Consider a geographic plot to show location data with your measurements, or build your customized channel view.
