How will you send the data
Hmm using some arduino code of course, I really have no idea what you mean.
There are lots of tutorials ( Your Environmental Data on Arduino IoT Cloud - Arduino Project Hub) which shows you how data can be send to the IoT cloud, with some simple code like this:
ArduinoCloud.update();
temp = readTemperature();
Sorry for not understanding, but i am new to this kind of stuff.
