How to determine mission parameters for temp logger iButtons

There are two fundamentally different ways of logging data. A : one can record the time stamp of the first measurement along with the measured value. Then, at the given sample rate, record the value only. This commonly applied method yields a data profile over time. B : one can record the time stamp of the first measurement and, for each measurement, increment a counter that is associated with the value. The result is a histogram that tells how often a particular value occurred during the mission. Loggers of the DS1921 series perform both methods simultaneously. The histogram continues to be updated with every sample, no matter whether rollover is enabled or the data-log memory is full. The histogram method, however, does not record when a particular temperature was measured. As long as the temperature stays in the desired range, the lack of time information is not an issu...
