+Backend software diagram:
+{{:iothings:proiecte:2023:server_sw_diagram_iot_drogeanu.png?800|}}
+A flask application runs on RPI5, it communicates with the MQTT broker, Mosquitto, and responds to the user's HTTP requests.
+A virtual python environment was used for development, so porting the application is easy.
+Frontend software diagram:
+{{:iothings:proiecte:2023:frontend_sw_diagram_iot_drogeanu.png?400|}}
+React was used for the frontend. The application does fetch for the limits already set and also a dataset to render on the graphical components like table and graph. Then an interval is set to fetch the data every second.
+====== Web interface  ======
+{{:iothings:proiecte:2023:web_interface-iot-drogeanu.png?800|}}
+The web interface presents a chart, a table, one fan status switch, one pump status switch and a download button.
+The chart allows to enable or disable the characteristics to allow observations only on a certain characteristic
+Each characteristic in the table has an upper and a lower limit option, which can be changed according to the plant's needs.
+By pressing the "Download" button, the user will get all the collected data in a "csv" format.
+====== Conclusions ======
+In conclusion, ESP32 is a fantastic option for an IoT project because of the different connection options it has.
+Using ESP-IDF compared to Arduino has proven to provide more support for handling tasks on ESP32, thus allowing efficient use of hardware resources.
+Using a web framework like Flask for the backend was a good choice, considering the scalability of this application.
