Hello,
I have experience around this, and worked extensively with cloud environments like Microsoft Azure and other similar. Basically the approach is to open an API that the sensor device can reach over HTTP/HTTPS and submit the measurements.
We could do this as a Proof Of Concept with hard coded data simulating submission from sensor to give you an idea of the speed and performance (milliseconds / seconds).
I'm available now to discuss details.
Best regards,
Hiten Parmar
