Here is one simple circuit of a general-purpose white LED security light with Passive Infrared (PIR) Motion sensing mechanism. At the heart of the circuit is a PIR sensor module SB0061. SB0061 is a ...

The motion sensor was designed using a pyroelectric sensor which is essentially a FET with a window in the case opening onto an infrared-sensitive gate. The circuit is monitoring the changes in the ...

There’s no shortage of ESP32 development boards out there, with many of them offering some “killer app” feature which may or may not align with whatever it is you’re trying to do. But if you’ve got a ...

If you’ve ever dealt with a brightly lit Christmas tree, you might understand the frustration of having to crawl underneath the tree to turn the lights on and off. [brmarcum] feel’s your pain. He’s ...

Many close-proximity motion detectors use the classic, widely available passive-infrared (PIR) approach, which is effective but has limited sensitivity and adjustability, and can’t “see” through ...

Fairport, New York -- Bosch Security Systems, a full-line manufacturer of high-quality security systems and components, has launched the Bosch ISN-CC1-50W wide-angle motion detector. This new Passive ...
