In the microcontroller era today, Arduino is more than just a tool to accomplish hobby tasks. There is actually a close relationship between microcontroller technology and home security, since you can ...

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 ...

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 ...

Halloween is coming up faster than you think: time to dust off the gravestones and the zombie lawn decorations! This year you may want to add a little something extra to give the trick-or-treaters a ...

「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 ...

Sometimes, projects start in somewhat unlikely places. This one began when [Istvan Raduly] scored a fake raven at a neighbor’s garage sale and decided to turn it into a thunder-and-lightning ...

First let's discuss the hardware. The sensor selected for this design is the Glolab (www.glolab.com) PIR325 dual element pyroelectric sensor. There are a number of different PIR sensors available, ...

There’s no shortage of ESP32 development boards out there, with many of them offering some “killer app” feature which may or may not align with whatever it is you’re trying to do. But if you’ve got a ...

Panasonic Industry unveils a new generation of passive infrared (PIR) motion sensing arriving with a clear message: performance no longer needs to come at the cost of design. A recently introduced ...
