[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 ...

In this tutorial we will use a Passive Infra-Red (PIR) sensor as an input to trigger a LED. A PIR sensor works by detecting heat as an object passes by it. Plug the micro: bit into the GPIO shield.

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 ...

The main aim of this mini-project is to demonstrate the working of a PIR motion-based light bulbs. This is to mainly minimize energy consumption and save electricity bills. Sometimes people forget to ...

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 ...

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 ...

Last year, I took a look at some mostly low-cost passive infrared (PIR) motion sensor modules. Then recently, I became more aware of cheap microwave radar motion sensor modules. The popular version of ...
