This is a great simple example of an IoT controller lab here from MIT/BYU heree: Temperature Control with an Arduino | Dynamics and Control - very clear and compact. I believe, the sample comes with a simulator to allow someone to program without the actual heater/ thermistor device.
The current code writes out to a Excel file.
Can I ask someone in the community(Academic Users Group or PI Developers Club) to share existing work or create a simple example module to write the data to PI vs the excel file to innovate on this education sample?
This would allow the students to send data PI to create a lasting record and allow for more advanced analytics to be done as part of the class.
Any level of help would help the students - good refrences, design ideas, code,etc...
