Notes : 

1)  The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not 

collect data. 

2)  The data collected is compared with the last data reported. If the data variation is greater than the ReportableChange 

value, the device reports according to MinTime interval. If the data variation is not greater than the last data reported, 

the device reports according to MaxTime interval. 

3)  We do not recommend to set the MinTime Interval value too low. If the MinTime Interval is too low, the device wakes up 

frequently and the battery will be drained soon. 

4)  Whenever the device sends a report, no matter resulting from data variation, button pushed or MaxTime interval, 

another cycle of MinTime/MaxTime calculation is started.
