Smart Lighting


Infrared automatic PIR sensor light


Using battery power supply, PIR sensors are easily used in entrance, bathroom, corridor, and other temporary lighting places.


Compared to sound-control lights, pyroelectric sensor has better anti-jamming effect. Only sensitive to human body temperature. To light, when person come, and light off when person leave.



1.Can PIR sensor detect animals?

PIR sensors are excellent in human and animal detection. They are mostly used in triggering an intruder alarm and activate household appliances upon the presence of a human.


2.Do PIR sensors work through glass?

No, alarm motion sensors do not work through glass. Most motion sensors use passive infrared (PIR) technology to detect motion. Changes in IR energy are not easily detected through glass. This is why motion sensors will generally not work through windows, which are usually insulated.


Senba Sensing Technology Co.,Ltd., was founded in 2005, with the focus on producing the top quality passive ir motion sensor. If you want to know more details, just feel free to contact us!
