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 ...

Geneva, Switzerland, July 24, 2023 – STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, is launching a novel ...

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, ...

Wave Sensors Can Track Multiple People . mmWave stands for millimeter wave and describes the wavelengths of the radio waves that are used by these sensors, which are small enoug ...

Eye-tracking technology looks to be one of the major tropes at CEATEC this year. One of many companies demoing a gaze-following setup is Fujitsu, which is showing off a prototype desktop PC with a ...
