Hi guys - I’m just starting my IoT journey, so apologies if this is a really basic question.
I need to create a system to sample data every second from a range of sensors, and log it locally on an SD card (in a time-stamped csv txt file) then send the data file to a cloud server (either when requested by the server (webhook?), or every hour or so).
Any advice or examples would be really appreciated. The logging to SD I’m sure I can muddle through, but I’m really out of my depth on the subsequent sending of the file (not just the values) to the cloud server.
[Logging the data directly in the cloud - thanks for the great examples out there - isn’t an option as the system is for use in remote locations, and wifi coverage (and eventually cellular with the electron) is not guaranteed.]
