adafruit_support, you have provided the most explicit, helpful information about my project. I'm so incredibly grateful.
Like grant77oksana, I'm also studying the how to of datalogging temp sensors. Ultimate plan is via wireless interface to a dedicated PC.
Due to high heat, three of my temperature probes would need to be provided by thermocouple. Others could be the Dallas as you suggest.
All temperature readings are required to be live on the PC as well as datalogged. Please correct me if I'm wrong but I wouldn't need to have an SD card in the slot to be able to stream data to the PC, view it live or datalog it? Is there any recommended program for this task?
Starting simple and adding features one step at a time is excellent advice. Thanks.
I'm compiling a shopping list based on the Mega plus the other items mentioned.
I'm well pleased, Thanks!
