Some key facts about the Livedemo:

• Our battery supplied sensor is mounted outside at a small lake.
• Every 15 minutes the sensor takes a measurement and transfers the data directly to a database
• A coarse geo tag is also transferred from the sensor which is also shown in the GUI
• Unregularly we are taking pictures of the sensor location which are also shown in the GUI. This gives a better understanding of the measurement results
• A Grafana based GUI is used to show the outputs of the sensor
