5.3 Example for MinTime/MaxTime logic

Example#1 based on MinTime = 1 Hour, MaxTime= 1 Hour, Reportable Change i.e.BatteryVoltageChange=0.1V
MaxTime

Wakes up and collects data
Note:
REPORTS 3.6V
MaxTime=MinTime. Data will only be report according to MaxTime (MinTime) duration regardless BtteryVoltageChange value.
Example#2 based on MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange= 0.1V.

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 change value 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.
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.
