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 ...

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 ...

Abstract: In recent years, with the increasingly serious problem of environmental pollution, the demand for real-time monitoring and early warning systems in homes and industrial places has been ...

Here is a simple general-purpose security alarm circuit built on the Arduino platform. It brings up an obtrusive alert signal when an intrusion/theft attempt is observed by its front-end sensor. In ...

Este projeto utiliza dois Arduinos Uno comunicando-se através do protocolo I2C. Um atua como mestre e o outro como escravo, formando um sistema de alarme com sensor PIR para detecção de movimento, ...
