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.
6. IR Delay Configuration
If someone or animal is moving in the monitoring area, RB11E will detect the infrared signal and the red indicator will flash once. In the mean
time, it reports occupied status (at the same time, other sensor status value are also reported).
To save the power, when RB11E detects the infrared signal, it will enter IRDetectionTime period. If there is no infrared signal detected in
IRDetectionTime period. It will report un-occupy.
IRDisableTime is the sampling period during IRDetectionTime (IRDisableTime are 30 seconds by default setting that PIR is off for first 70% of
the period; on for rest 30% of the period).
For example, after triggered, the PIR will turn off the infrared probe for 21 (30 * 70%) seconds to save the power, living objects within this period
will not be detected. PIR will re-open detection function after 21 seconds, if it detects living objects in this period, the IR delay time will be
extended for another 30 seconds till no infrared signal is detected and IRDetectionTime period is due and RB11E will then report un-occupy.
Note
：
IRDisableTime >=5 s, IRDetectionTime>= IRDisableTime
Default disabletime
：
30s detectiontime
：
5min
The infrared sensitivity adjustment knob can be manually adjusted to change the sensitivity of the infrared detection. When the clockwise rotation,
the higher the infrared sensitivity, the easier it is to trigger.
Disabletime and Detectiontime
IRDisableTime is the sampling period, and IRDetectionTime is the detecting period.
To save power, the sensor will be in the sleep mode for the first 70% of the IRDisableTime and awaken for the last 30% of the IRDisableTime.
If living creature is detected during the last 30% of IRDisableTime, the IR delay time will be extended for another IRDetectionTime till no infrared
signal is detected.
If no living creature is detected during IRDetectionTime, RB11E will report “unoccupied” along with other sensor status, such as
temperature,illumination, etc.
