Internet access

Once we have collected data from the sensors we want to get access o them. This can be accomplished most easily by transferring the data over the Internet. Most of the time we also want to plot the data in some form or another. Often it is also desired to see real time data.

In this course we will have a look into two ways of accessing our data:

• a WEB server implemented on the ESP32
• transfer of the data through MQTT to a Cayenne server offering display and logging of our data.
