Arduino Fire Alarm Project Using MQ2 Gas and Flame Sensor

[@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.

How to connect sms for Arduino to breadboard?

[@jashvinsharma688]

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

[@harikrishnakoyala5443]

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

[@shevankaniral4628]

Are you using an active buzzer or a passive buzzer?

[@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?

[@monmon-jo6fs]

Its work with esp8366 module? Not included arduino uno

[@arduinopoint001]

Yes. But you need to modify the code.

how to make the connections with nodemcu ??

[@adambeedle]

Great project bro 👍

[@arduinopoint001]

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

[@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.

Hi why the gas sensors can't detect?

[@arlyndumadiego5749]

Plss help me🥲

[@arlyndumadiego5749]

The gas sensor is not working

[@AdityaKumar-qr8kj]

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

[@arduinopoint001]

Yes, you can.

[@AdityaKumar-qr8kj]

@@arduinopoint001 thanks bro

[@suvaneesh9253]

Hi can the same code used for esp32?

[@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

Brother, code link is not working. Please help us to get the code

[@arduinopoint001]

It's working.

[@mdahasanhabib1225]

Explanation good

[@arduinopoint001]

Thanks for your compliment 😃😃😃.

[@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 😃.

Hello sir I have a question

[@diabolsensei]

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

[@OnyxDrago]

Can i use arduino wemos d1r2??

[@MarjiaAkhter-d6u]

The code is showing error please help me

[@FahadKhan-je1jz]

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.
