Data to the cloud without WiFi

Hi Arduino Community,

I have a quick question. What other ways are there to send data to a cloud server? I have a few outdoor sensors for hiking that I would like to capture data and send it realtime to the cloud.

Thanks!

Or if you are in many of the areas without cellular signals, then you have to go satellite (which is expensive). That is the sort of thing offshore ocean monitoring buoys use. Up here in Washington state, there are quite a few of the areas around Mt. Rainier or in the Cascades for example where there is no cell service so something overhead is about the only option.

Thanks so much for your answers. Yes, it could be that there is no cellular signal. I was thinking about a smart solution that saves the captured data on a memory card or device and sends it out as soon as it finds a new signal. But I have no idea what component and technology I would need for that. Any idea?

Thanks!

That would be fine if the gadget was moving so that it would periodically get a signal, however if it is in some area where you want remote temp sensing for example and it does not get a cell signal, that is not likely to change, so you could log the data and capture it with something you take out to the sensor, it will not connect if there is never a cell signal there. We have a lot of places around here in the mountains where it would be cool to have a temp reading etc. but they never see a cell signal. One more complicated scheme would require two parts to your gadget - something that sits up at a high point that can connect to a cell site and then your other gadgets that use low power rf to send the data to your relay station (they would need to be line of sight, but there are some inexpensive RF links that have been discussed here. That could work, but it is getting more complicated now.

'realtime' and 'store until it finds a signal' are two completely different things. :slight_smile:
An SD card is the usual way to store gigabytes of data until you have time to process it.
