Intoduction:
From the three problems presented, we were pretty quickly sure that we wanted to take problem one. As we saw the potential here for real-life use and meaningful further development of our prototype.
Our goal was therefore to plan a prototype that was as suitable and optimized as possible, as well as to invest further time in planning future optimizations.
Problem Definition:
Since the framework of the task and a possible solution approach had already been specified, we invested our time here primarily in order to have the problem and all important information clearly in front of us once again.
From here, we first thought about what we could optimize in the proposed solution. We then created an example persona of a farmer so that we could later check whether our solution also fits the user.
Our Solution:
So after we had come up with a suitable solution, we realized that this would not be possible on our own, so we joined forces with another group to achieve our goal. While we wanted to take care of the sensors on the tree, their task was to build a network that was as stable and fail-safe as possible and to provide a graphical representation of the data.
Our product consists of three main components: a 4.5k Ohm resistor, a DS18B20 temperature sensor and an ESP-8266 microcontroller. The resistor is used to limit the current in the circuit. The DS18B20 sensor measures the temperature. The ESP-8266 microcontroller is used for data processing and communication.

Further Investigations:
We then carried out further research with regard to energy supply as we have the impression that this is where the greatest need for improvement lies.
