| The values will be collected through sensors managed by an ESP32 and stored in a Firebase database. The user can initiate the recording from a web interface at bedtime and can visualize the progression of measurements throughout the night on the same interface. This will also allow the evaluation of whether certain periods during the night are better than others. An overall score for the surrounding environment's quality, derived from the five metrics, will be displayed by the web interface. | The values will be collected through sensors managed by an ESP32 and stored in a Firebase database.
