Thanks,  
Maxime

These samples are averaged in 2-minute intervals, which are sent in data reports to our database. Those 2-minute reports are the smallest frequency (“real-time”) averages you can see on the map. Sensors that have an SD logger and an SD card will store these 2-minute reports on the SD card as well. Occasionally, a user will have an interest in storing data o…

Hope this helps!
