Fire Alarm Using Flame Sensor and Arduino

How to make a Fire Alarm with Arduino

In this tutorial we will learn how to make a Fire Alarm Using Arduino and Flame Sensor.
For this tutorial we will use Flame Sensor, Led, Buzzer and Arduino UNO.

Hardware Required :

  • Arduino
  • Flame Sensor
  • Buzzer
  • Led
  • Breadboard
  • Jumper Wires

Project circuit :

Project circuit diagram is shown below.

How Flame Sensor Works

These sorts of sensors are used for brief range fire detection and may be wont to monitor projects or as a security precaution to chop devices off / on.

The flame sensor is extremely sensitive to IR wavelength at 760 nm ~ 1100 nm light.

Analog output (A0) : Real-time output voltage signal on the thermal resistance.

Digital output (D0) : When the temperature reaches a particular threshold, the output high and low signal threshold adjustable via potentiometer.

Pins :

  • VCC    —  Positive voltage input: 5v for analog 3.3v for Digital.
  • A0      —  Analog output
  • D0      —  Digital output
  • GND  —  Ground
