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 ...
An Arduino project implementing a security alarm system featuring PIN code access via a 4x4 keypad, status updates on a 16x2 LCD, motion detection using an HC-SR04 ultrasonic sensor, and ...
This project demonstrates a simple motion detection and alarm system using an Arduino Uno and a PIR (Passive Infrared) sensor. When motion is detected, the system activates a buzzer and an LED to ...
We’re still not sure exactly how [connornishijima]’s motion detector works, though many readers offered plausible explanations in the comments the last time we covered it. It works well enough, though ...
Kangaroo’s latest motion sensor adds entry detection to the mix, but its lack of geofencing capabilities or support for any type of security camera makes it tough to recommend. It’s one thing to snap ...
