Every 10 seconds the AirVisual Pro records Time, PM2.5, CO2, Temperature, Humidity, AQI, and Outdoor AQI data.

These detailed historical data logs are held in the monitor's internal memory for up to 5 years. At any point here-within, it is possible to retrieve all of your device's data by wirelessly downloading the comma delimited .txt file, via Samba. Detailed information on how to do that here:

It is also possible to receive your Pro's measurements in real-time via the AirVisual mobile app. The app updates every minute, so that you are constantly aware of the air quality readings of your monitor.
