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 ...

It is likely that many of us will at some time have experimented with motion detectors. Our Arduinos, Raspberry Pis, Beaglebones or whatever will have been hooked up to ultrasonic or PIR boards which ...

Makers and developers looking for a motion sensor Arduino Shield, are sure to be interested in this new ICU-Duino which has been created by Patrick Thomas Mitchell based in Ottawa, Canada. The ...

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, ...

近年はWi-Fiの信号を利用して対象の行動を検出するWi-Fiセンシングが注目されており、2025年9月26日に公開されたWi-Fi規格の「IEEE 802.11bf」ではWi-Fiセンシングが規格化されました。そんな中、20年以上にわたりIT業界で働いてきたフランシスコ・パーチェ氏が ...
