Thanks to the company’s technology and new pyroelectric ceramic materials, Murata was able to craft a smaller lead-free, surface-mount pyroelectric infrared (PIR) sensor. Thanks to the company’s ...

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 ...

This circuit is from the GLOLAB web page. The document referenced here includes an excellent design as well as an excellent tutorial on PIR devices. You've probably seen these devices in homes and ...

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 ...
