6. PIR Detection
If there is to be a person or animal movement detected by the R718PQ within the monitoring area, the device reports the detected Occupy status =
1 along with other sensor status value.
If there were no movement detected within the monitoring area within the following 5 minutes IRDetectionTime (Default 5 minutes, configurable),
then the device reports Vacant status = 0 along with other sensor status value.
To save the power, when R718PQ detects the infrared signal, it will enter IRDetectionTime period.
When there is no infrared signal detected in IRDetectionTime period, then it reports Vacant status = 0.
IRDisableTime is the sampling period during IRDetectionTime
(Default IRDisableTime being 30 seconds; first 70% of the period = 21s being off and for rest 30% of the period would be on) and no movement
will be detected during IRDisableTime.
The detection will be resumed after the 21s IRDisableTime, and the IRDisableTime along with IRDetectionTime will be extended for another 21s
if there is to be any movement detected again.
The above described cycle continues until there is no longer any movement detected and the device reports Vacant status = 0.
Example1:
While IRDetectionTime is 60 secs and IRDisableTime is 30 secs, no living creature is detected after triggered.
R718PQ will report un-occupied after 60 secs(IRDetectTime).
Example2:
While IRDetectionTime is 60 secs and IRDisableTime is 30 secs, living creature is detected during 25
th
sec.
R718PQ will restart IR detect procedure(IRDetectionTime).
No living creature is detected during next IRDetectionTime and R718PQ therefore report un-occupy.
7. Installation
This product comes with waterproof function.
When using it, the back of it can be adsorbed on the iron surface, or the two ends can be fixed to the wall with screws.
Note:
To install the battery, use a screwdriver or similar tool to assist in opening the battery cover.
Note on battery use:
Because the passivation of the ER battery electrode surface is an inherent characteristic of lithium thionyl chloride batteries, before using the
ER14505M 3.6V 2200mAh lithium thionyl chloride battery, the user can use a 33 ohm resistor to activate the battery for 1 minute to actively eliminate
the battery hysteresis.
