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. GlacialLight has added the GL-PIR10C, a versatile infrared motion sensing ...

For example, while playing Ring Fit Adventure, players can check their pulse by holding their thumb against the IR motion sensor/camera. Within Resident Evil Relations, the IR sensor was used to ...

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, ...

Truck-Lite recently rolled out a new feature for its Super 80 LED [light emitting diode] interior trailer lamp – an infrared [IR] motion sensor to automatically turn the trailer dome light on and off, ...

A new motion sensor incorporates micromachined thermal transistors to facilitate human presence and motion detection in security systems, home automation equipment, and Internet of Things (IoT) ...

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 ...

Some motion sensors are based on optical measurement technologies to provide accurate velocity and position measurements without requiring physical contact with the object or surface being monitored.
