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 ...

You can use mmWave sensors to monitor presence rather than simply detecting motion.

The project develops a USB powered IR sensor by using an ATtiny13A, an IR motion sensor, and a metal candy Mario Bros mushroom tin. The project develops a USB powered IR sensor by using an ATtiny13A, ...

Passive InfraRed sensors (PIRs) are electronic devices which are used in some security alarm systems to detect motion of an infrared emitting source, usually a human body. All objects, living or not, ...

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 ...
