W216S Anti- WiFi Type PIR Senser from Senba Manufacturer

Overview

W216S PIR sensor is a type of anti- WiFi. It is widely used for Security system, Doorbell, IP Camera, Lighting, home application. The product is a type of intelligent PIR sensor which integrates digital control.

PIR sensor sense the motion object, always used to detet the human. There is a detect rang for the PIR sensor. When a people move in or out of the detect rang, the PIR sensor will be triggered. PIR sensor are low-power, small, easy to used. For this reason it can be used for the alarm system and lighting control. PIR sensor also named passive infrared, Pyroelectric or IR motion sensor.

FAQ

1.What can trigger a PIR sensor?

Five Causes of PIR False Alarms. The first cause of PIR false alarms is low or unstable voltage at the detector. Test to make sure the voltage at each PIR is above 13VDC and stable. The second cause of false alarms is sudden infrared movement / heat changes in view of the detector.

 

2.How do PIR sensors work?

When the sensor is idle, both slots detect the same amount of IR, the ambient amount radiated from the room or walls or outdoors. When a warm body like a human or animal passes by, it first intercepts one half of the PIR sensor, which causes a positive differential change between the two halves.
