DWM-PM-8 Mini Infrared PIR module PIR motion sensor module, Max detection distance is 5 meters. If anyone moved in that range, Alarm pin will go high. The signal duration can be set as 0.18s, 5s,5s, 10s,，15s,20s,30s,,45s,60s,90s,120s,180s, 300s. 0.18s is the default setiing before we ship to customer.
LDR worke mode: Customer can sold a LDR then the module will not work at the day time and will work at the evening. for more information about how to use this module you can visit our blog and see the article:
