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 uses an Arduino board with a PIR motion sensor to detect movement. When motion is detected, an LED lights up and a buzzer sounds. It's ideal for simple security systems or motion-based ...

This project uses a PIR (Passive Infrared) sensor to detect motion and displays the status on an I2C Liquid Crystal Display (LCD). When motion is detected, a message is shown on the LCD and printed to ...

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 ...

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 ...

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 ...
