Fieldtest of the tracker in summer 2017
From monday, 24th of august, the first energy-autonomous tracker (without batteries), was tested in Freiburg.
Our system was attached to a sheep as a collar, collecting for several days the temperature gradient at the TEGs, activity and energy-state of the system.
All data was directly sent through a gateway on the farm to the webserver, displaying the data live here. The displayed the incoming data was not filtert, nor postprocessed. Transmission errors also occour, leading to false temperatures.
