+## Hardware for automated data labeling
+
+In the Self-Learn part, you discovered the ESP and how to program it. We will use such an ESP in a special Addon, that can be attached onto a Senseo Coffeemaker to detect which Product is produced by the coffeemaker and label the data, accordingly. The data of the Coffeemaker-Addon will later on be needed to be synchronized with the data of the energy-monitor (which also has an ESP inside).
+
+In this image you can see which sensors the addon consists of.

 ## Synchronisation:
 
 As you can see, we have another data source in addition to the power box. Now the synchronisation of this is crucial. We have set up a so-called NTP (Network Time Protocol) server service on our laptop server. The power box sends a request every 60 seconds to the NTP server and obtains a new time stamp. :books: This should also be done by the coffee machine. This means that synchronisation in this project is implemented via a central server service.
