 ==== 3.3 Results in Grafana ====
-After setting up the module, programming the DS3231 accordingly and uploading the code to the ESP32, the results could be seen in the pond monitoring station dashboard in Grafana. For testing outdoors, the components need to be isolated safely to not get into contact with the water from the pond, which was not yet done. Therefore, for testing, the measurements were taken indoors in 1-minute intervals during a hot summer day. The results of those measurements can be seen in figure 4. The temperature spike from the bottom water temperature sensor was due to holding the probe in the hand, the following drop was due to the sensor being placed in a colder glass of water for a short moment to test the responsiveness of the sensor. As can be seen, the sensor needs approximately 5 - 7 minutes to really get into thermal equilibrium with its environment

 At the pond, the connection of the ESP32 to the local WiFi network might not be good enough for data transmission. Before installing the station, the signal strength at the pond should be tested. In case that it is insufficient, some of the ESP32 modules, especially the Wrover-modules, offer the possibility of soldering an IPEX connector to it; some already have one connected in place. The IPEX connector makes it possible to attach an external antenna which increases the signal strength. However, it is not possible to use an external antenna if the PCB antenna is still connected. To change the antenna used by the ESP32, the small 0Ω SMD resistor connecting PCB antenna and MCU must be removed and connected to the IPEX connector instead. As the components are very small, it might not be easy to do that.
