Arduino KY-026 sensor Project

Fire detection system with Arduino

Purpose of this project:

In this project a fire detection system will be built with Arduino. It mainly uses a KY-026 flame sensor, buzzer and LED.

When the flame sensor detects a fire, the Arduino board orders the buzzer to ring and the red LED to light up.

Necessary components

  • Arduino UNO
  • KY-026 sensor
  • Buzzer
  • 1 resistance of 220Ω
  • 1 red LED
  • connecting wires

Mounting

To make the assembly, we can connect:

  • 2 (+) red LED and buzzer terminals to pin 4 of Arduino
  • 2 (-) red LED and buzzer terminals to Arduino GND pin
  • DO pin of KY-026 sensor to pin A0 of Arduino.
  • VCC pin of KY-026 sensor to 3.3V pin of Arduino.
  • GND pin of KY-026 sensor to GND pin of Arduino .

Program

The Fire Detection System program is as follows:
