| After the code for each sensor was written and also connecting worked mostly fine for the Arduino board, the change to the ESP32 had difficulties.\\ | After the code for each sensor was written and also connecting worked mostly fine for the Arduino board, the change to the ESP32 had difficulties.\\ | ||
| The first problem was to figure out, how to connect the board to the Wi-Fi. This it took especially long due to the fact that there are various ways to do it but many codes are difficult to understand also the strength of the Wi-Fi connection at each home is of different quality. In our case all of us had poor to medium connection, which had the effect that even when a code would work it would not connect. This leads us also to the problem that the ESP board needs a nearby Wi-Fi connection to use it on the fields or garden. The problem is that many fields do not have such far reaching connections on the fields yet. We think this will change in future due to the fact that more and more agriculture work will be done with the help of Wi-Fi to control instruments and machines more easily and effective. In contrast to the Arduino board it has the advantage that you do not have to go to the place and connect your laptop. After we managed to move the sensors to the other board, we thought about the problems the station might have.\\ | The first problem was to figure out, how to connect the board to the Wi-Fi.

| - | Secondly, we tested both the Arduino and the ESP32 version of our project. Here we could see that the sensors by the ESP32 were less sensible which leads to less exact measurements. For example, the LDR (Photoresistor) is less sensible in case of the ESP version and shows the same values for different light conditions. It was much more sensible by the Arduino board.\\ | + | Secondly, we tested both the Arduino and the ESP32 version of our project.

| Fourthly, it became clear that the station could not be used effectively outside in this state. The biggest problem was that the station is not weatherproof. In the event of rain, for example, it would damage the individual sensors and the board. \\ | Fourthly, it became clear that the station could not be used effectively outside in this state.

| Therefore, we decided to build a box. The problems which occur by building it were, to design it. Another problem might be that the often usage of the soil sensor and water level sensor might cause corrosion.\\ | Therefore, we decided to build a box.
