Automatic Light Controller with PIR and LDR Sensors This repository contains the implementation and documentation of a project using an Arduino Uno R3 microcontroller to control lights automatically ...

This project uses an Arduino Uno to build a burglar detection alarm system with a PIR sensor. The system triggers an alarm when motion is detected, signaling with an LED and a piezo buzzer. This code ...

Street crime is very common in the modern century. Everybody needs to feel secure when they are at home either while sleeping at night or during day time. So, many security alarm systems are available ...

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 ...

Proximity sensing is a common application for intruder alarms, light switches, and other home and industrial automation applications. There are multiple methods of proximity detection used in the ...

今回は、Arduinoで超音波センサーを使って距離を測る方法についてご紹介します。 超音波センサーは触らずに物体との距離を測ることができます。 応用すれば、「物体が一定の距離まで来たら停止する」という動きをロボットにさせることもできます。

Wireless sensor networks are nothing new to Hackaday, but [Felix]’s wireless PIR sensor node is something else entirely. Rarely do we see something so well put together that’s also so well designed ...
