I am building a sketch that reads a DHT22 temp/humidity sensor for climate and a DS3231 RTC for time, based based upon either toggles a relay on an 8 channel relay board. I am wanting to display this data and relay states to my ThingSpeak channel and though I am still tracking down a tutorial the produces a functional result, I find that I also do not know how the data will be sent into the internet. I have a basic understanding of what might be involved in the process, but I don't understand how the data that is to be sent is bundled together (array? string?, String?) and will this data be sent as a Serial feed, or does "serial" only apply when the data is to be viewed by the serial monitor?
Any help of insights will be greatly appreciated.
I am using an EtherMega, but also have a Mega clone and Ethernet Shield clone. The DHT data points are float types
