Introduction: Fire Alarm
IR is a very useful module but do you know and IR also for flam detection. Using this fact we are going to make a fire safety device with Arduino.
Step 1: Material
Arduino UNO * 1
IR Module * 1
LED * 1
Buzzer * 1
Jumper wires
Bread board * 1
Programing Cable
Step 2: Connection
IR module---------------------- Arduino------------------------- LED
D0 ------------------------------- pin no. 2
Vcc------------------------------- 5v
--------------------------------------And ---------------------------- Gnd
--------------------------------------Pin no. 13 ---------------------+ve leg
Step 3: Explanation
Flam emits multiple radiations include visible lights and IR lights these IR rays detected by the IR receiver module and give High signal which is detected by the Arduino. Arduino responds to these signals.
Step 4: Code
Download and upload code on your Arduino UNO. If you don't have the Arduino IDE software click here to download and install

Step 5: TEST
light up match stick or lighter and take it close to the Module.
Step 6:
Here we have done, the Led will lit when it detects flames.
If you want to make it a professional safety instrument you can print this entire system on a Single PCB, You can directly order from nextPCB. They have amazing quality and they are budget-friendly, Quick delivery. I received my PCB within 4 days. I highly recommend try once.
