[ladyada] has a freshly-published and amazingly thorough tutorial on passive infrared (PIR) motion sensors. Most often seen in security floodlights and automatic doors, in creative hands these sensors ...

小型のPIRモーションセンサー「SR602」を購入したので検証してみました。センサー本体の直径は約9.6mmで、消費電力も少なく使いやすいセンサーです。 本体の幅(9.6mm) 基盤を含めた幅(15.4mm) PIR（Passive Infrared：パッシブ赤外線）センサーは、人や動物から放射 ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

A PIR (Passive Infrared) sensor is widely used for motion detection by sensing the infrared radiation naturally emitted by warm objects such as humans or animals. The sensor remains passive, meaning ...
