DWM-PM-8 50uA Lowest standby Current 0.18s to 300s Delay Time Mini Infrared PIR motion sensor module
Power supply is 3.3V to 15V.module include LDO;
Sensitivity can be adjust,
Delay time can be adjust,
Trigger mode is be defined as repeatable;
Controller MCU built-in sensor：strong interference rejection capacity,Low EMI.
[small size,Wideer working voltage range,small current,stable performance]
Repeatable: if the moudul detect human body is moving,output high level at once,this moment,at delay time,if PIR detect body is moving once more, then delay time reset,be cleared to zero,start counting from zero,until the delay time to over,will output low level,waitting next trigger.
Unrepeatle:if the moudul detect human body is moving,output high level at once,this moment,signal input line be closed,PIR detect is disabled, until the delay time to over,will output low level,waitting next trigger.
LDR worke mode
Customer can sold a LDR then the module will not work at the day time and will work at the evening.
Sensitivity adjust and Delay time adjust
