Flame Detector Alarm using Arduino and Flame Sensor

The Flame Detector Alarm project is a safety-based application that uses an Arduino Uno and a flame sensor to detect fire or flame within a certain range and trigger an alarm system. This project is ideal for early fire detection in homes, laboratories, workshops, or other sensitive environments where flammable materials are present.

The core of this system is the IR-based flame sensor module, which can detect flame sources like lighters, matches, or candle flames from a distance of 1–3 feet depending on the intensity. The sensor continuously monitors the environment and sends signals to the Arduino Uno. When a flame is detected, the Arduino activates a buzzer to alert users immediately. An LED can also be used as a visual indicator.

This project demonstrates basic sensor interfacing, digital input reading, and output control using Arduino. It’s an excellent beginner project for students to understand how embedded systems can enhance safety and automation.
