The Fire Alarm System Project integrates Arduino with temperature and gas sensors to identify potential fire risks. When abnormal temperature or gas levels are detected, the system activates an alarm, ...

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 ...

Fire safety alarms are crucial in both residential and industrial environments. Early fire detection can prevent significant damage and save lives. Flame sensors offer one of the most efficient ...

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 ...

Abstract: LPG is an alternative fuel used for daily use. Due to its low cost and ease of installation. This article covers an Arduino-based gas detection system that uses an Arduino UNO R3 board and ...

Gas leaks can pose serious safety risks, especially in homes, kitchens, and small commercial spaces. In this project, you'll learn how to build a simple and budget-friendly gas leakage detector using ...

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 ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...
