Once started EasySense Q
records data at a rate of 40
samples per second until it has
captured 1000 samples. At this
point the sample rate halves
(i.e. 20 samples per second) and
every other sample is discarded
(leaving 500 samples). It will
continue at this speed until it has
captured another 500 samples
(1000 total) then the sample rate
halves (i.e. 10 samples per
second) and discards half the
stored data, and so on.
EasySense Q will continue to
record data for up to 30 days.
In EasyLog mode the EasySense Q
will stay awake until the interval
between readings reaches
5 seconds or greater – at this point
it will begin to use low power
(sleep) mode between samples to
conserve battery power.
