[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 ...

「micro:bitとキットでマイコン制御」では、micro:bit V2と市販のセンサーキットの「KEYESTUDIO 37センサースターターキット micro:bit V2付」を使って組み込み技術に必要なマイコン制御の基本を学習します。 【第16回】：第1回の記事で準備した実習環境に、PIR ...

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 ...

This project demonstrates a proof-of-concept (PoC) test of a PIR (Passive Infrared) motion detector interfaced with an ESP32 and a 16x2 I2C LCD. The system detects movement and displays the motion ...

The Virtual PIR Sensor integration for Home Assistant introduces a unique approach to motion detection, utilizing the ubiquitous ping operation to simulate passive infrared (PIR) motion sensors within ...

ICP DAS USA releases PIR-130-DC, a 1-channel passive infrared (PIR) sensor module that detects human-body generated infrared waves within a range of approximately 8 meters (315 inches) in diameter ...
