The presented schematic shows how to build a simple PIR motion sensor. PIR sensors allow motion sensing, it is almost always used to detect whether someone has moved in or out of the sensors range.

Unlike infrared optical sensors that use an LED transmitter and IR receiver, the PIR emits nothing. As its “passive” name suggests, it responds only to infrared energy radiated by the object being ...

GlacialLight has added the GL-PIR10C, a versatile infrared motion sensing switch, to its popular range of lighting products.This passive infrared (PIR) motion sensor can be connected to a wide range ...

STMicroelectronics is launching a human-presence and -motion detector to enhance security systems, home-automation equipment, and IoT devices that typically use passive infrared (PIR) sensing. The ...

Recently, I exhausted my stock of common passive infrared (PIR) motion sensor modules and was looking for a new one to play with. I searched the web for a small type with self-contained electronics.

Smart lights are a great way to enhance home security. Being able to flip on the lights remotely or automatically, you can give the impression that someone is home and expose potential intruders. It’s ...
