4 Elements Infrared Motion Sensor B2X2 for Lighting

Overview

B2X2 is quad elements type products. With same horizontal and vertical detection angles. It is widely used in ceiling light.

B2X2 PIR sensor with same horizontal and vertical detection angles. It is widely used for ceiling light, intrusion detector. PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensors.

FAQ

FAQ

1. What can trigger a PIR sensor?

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. Do PIR sensors work in the dark?

Yes, motion sensors work in the dark. The way that a motion sensor detects movement has nothing to do with how light or dark it is in the immediate area. ... Since infrared energy is present and can be detected regardless of the amount of light in the environment, a PIR motion sensor will work just fine in the dark.
