d = duration of data recording in days
n = number of values to be stored (without date and time)
M = averaging interval in seconds

Example:
Storage of eight measured values per minute.

Number of Bytes = 8 + (4 * 8) = 40 bytes per record
Memory demand per day = 24 * 60 * 40 = 57600 Bytes

At 7 MBytes internal flash 7 * 1024² * 60 / (40 * 86400) = 127,4
days can be recorded.
