Feather BME-280 CircuitPython Test 2
This is a stock Adafruit Feather with the BME-280 chip reporting to a webpage to build a CSV file. There is also server side code which is currently dumping it into a CSV file on this page.

The hard part is just getting the data to the server over a URL and CSV is quick and easy. We can certainly save to different databases, etc.

It's very interesting to see how the numbers changed abruptly. It uses the pressure/altitude to adjust the temperature and humidity readings and for some reason all of them shifted. I switched it to a power supply. Maybe there is something else to make this sensor reliable. I was just reading that we can apply our own calibration by using a known sea level https://forums.adafruit.com/viewtopic.php?t=138414 I'll let you know how it goes with the external sensors once my cables arrive.

Note, I'm thinking of doing a test with the Arduino editor and C instead of CircuitPython. It's amazing that they got a code interpreter running on C device to run Python. Though it can be a little laggy to get it to run and that's 2.8MB of code...maybe writing native C would be better. It's nice to think we could do something with the extra 2.8MB of storage. (make it into a "datalogger" USBC device?

Note: calibrated to -9.2F, -4.2% on 10-10-10 at noon
