Information about the indoor climate can be consulted via a mobile phone by scanning the QR code above the sensor. Users get direct insight into the conditions in the room as they are at that moment via a web app. There are 3 categories: good, moderate, and bad. Users also have insight into the history of the indoor climate, so you can see how the air quality has developed in recent hours, for example. You can receive a message if a limit value has been exceeded, so that you can take immediate action.
