Arduino Fire Alarm Project Using MQ2 Gas and Flame Sensor

This project interfaces Flame Sensor and MQ 2 Gas Sensor with Arduino and learns about all the procedures needed to develop Arduino Fire Alarm System. The flame sensor module has a photodiode for light detection and an op-amp for sensitivity monitoring. It is used for fire detection and makes a HIGH signal. Arduino detects the signal and alerts the buzzer and LED by turning it on. The flame sensor utilized is a flame sensor based on IR.
The MQ 2 sensor has an electrochemical sensor that varies its resistance to different flammable gas concentrations.
Components Required for Arduino Fire Alarm Project:
1. Arduino Uno × 1 amzn.to/3mYHkAN
2.MQ-2 Gas & Smoke Sensor × 1 amzn.to/3zYfAT1
3. Flame Sensor × 1 amzn.to/3zYfAT1
4. LED and resistor kit × 1 amzn.to/3eej3CU
5. Buzzer ×2 amzn.to/3xL0QFc
6. Breadboard × 1 amzn.to/2RLJpEM
7. Jumper wires kit × 1 amzn.to/2QEE41B
8. USB cable type A/B × 1 amzn.to/3mYQNrP

[@shevankaniral4628]

Are you using an active buzzer or a passive buzzer?

[@suvaneesh9253]

Hi can the same code used for esp32?

[@calvinlenarddelacruz6643]

how can i adjust the value of the gas sensor threshhold so the buzzer and led will react when the MQ2 led is on?

[@harikrishnakoyala5443]

Can u please say that y u have set flamesensor =low though u have got flamepin value=1 in serial monitoe

[@adambeedle]

Great project bro 👍

[@arduinopoint001]

Thanks for your compliment, Bro 😍😍😍. It makes my day 😃😃😃.

[@mdahasanhabib1225]

Explanation good

[@arduinopoint001]

Thanks for your compliment 😃😃😃.

[@OnyxDrago]

Can i use arduino wemos d1r2??

[@diabolsensei]

i have done same as your but my led doesnt turn on can you help

[@sebastianyudithprastiawan2926]

why the gas sensor isn't detect, ledred1 and buzzer1 didn't work?
I do simulation using proteus

[@arduinopoint001]

Check your threshold value, when use analog output. And adjust the sensitivity by rotating the preset knob, when use digital output.
And also check the Proteus support MQ2 gas sensor properly.

[@jashvinsharma688]

Code is not Working Properly , i Checked all the Connections thrice Flame Sensor , Mq2 , LEDs , Buzzers

Hello sir I have a question

[@Ansori-cq5pq]

Please sensor gas and sensor dht11 with arduino uno

[@thankgodaugustine9975]

Please how could I know all the material needed for the project u just did.

[@atharsayed6904]

1 Breadboard
1 flame sensor
1 MQ2 smoke sensor
jumper wire (Male to Male similarly M to F )
led's
arduino uno
programming cable
Buzzer
this is all you need

[@arduinopoint001]

I already gave the required instrument list in the description.
1. Arduino Uno × 1
2.MQ-2 Gas & Smoke Sensor × 1
3. Flame Sensor × 1
4. LED and resistor kit × 1
5. Buzzer ×2
6. Breadboard × 1
7. Jumper wires kit × 1
8. USB cable type A/B × 1

[@monmon-jo6fs]

Its work with esp8366 module? Not included arduino uno

[@arduinopoint001]

Yes. But you need to modify the code.

[@riteshgowda4604]

how to make the connections with nodemcu ??

[@md.fhossain5014]

nice

[@arduinopoint001]

Glad you like it 🥳

[@paulmercado1969]

how will you add an sms alert on this one

[@arduinopoint001]

Wow! That's good. You are creative thinker. I didn't work on the idea. But this idea is good. You can try it using GSM module.
Let me know after finishing your creative project 😃.

[@AdityaKumar-qr8kj]

Bro can the power give to this model by charger
Yes )no

[@arduinopoint001]

Yes, you can.

Can we connect gsm sim800L module in it

[@FahadKhan-je1jz]

And Lcd 16x2

[@arduinopoint001]

Yes, you can. But you need to change the code according to the gsm module and LCD.

@@arduinopoint001 can you help me, can you share code for it hmm

[@shevankaniral4628]

Could you please upload the code. Its not accessible

[@arduinopoint001]

Now it's accessable.

[@insongajes3198]

Why my gaspinvalue is too low it is on 35 how to make higher

[@arduinopoint001]

Rotate the potentiometer to adjust the alarm on-off level.
