SD card data storage

How many days can the SD card coming with the device can record data? when do we need to change the SD card as it is full? Trying to understand when to clean data on SD card. Thanks

Hi @Mehtap_Abul

Air quality data isn’t very large in size, and so a 32GB card is actually capable of holding quite a bit. We have seen up to a couple of years of data stored successfully. However, we always recommend that you set up some sort of regular interval at which to check on the SD card to ensure that data is being logged correctly.
