LPG Gas leakage detector project using Arduino

It is a tutorial video to make a LPG gas leakage detector system using Arduino.
here I have used MQ2 gas sensor & 16x2 LCD display.
the circuit diagram is included in this video.

Hii sir very good Chala bagundi sirabdverygoodIdea

[@electronic7979]

Nice project

[@anlonjs517]

I suggest it would be better if you add red led light which enables on alert.

[@kavitha.r8987]

What's the size of the perfboard I want to do the project and finish it by 10 days

[@luanngothanh7661]

Great 😚

[@santhiyap6047]

Hello....after programming when I connecting to battery buzzer starts alert sound....how to rectify it

[@technoreview85]

Adjust the sensor sensitivity by tuning the preset

[@santhiyap6047]

After I adjusted alerts sound stopped..and then when I give smoke there is no alert sound.....y

[@technoreview85]

Keep the potentiometer at perfect potion when the sound turned off. It needs some tuning

Bro, good day , can it detect refrigerant gas??

Hello sir .. we are working one science project.. we need this apparatus... Will you be able to send us this apparatus?

Arduino ka coding payle Kiya tha na badma Kiya tha

[@markjustindelacruz3583]

I have done this project, but it detects a gas leak and beeps after a few seconds, even without the lighter. What do you think may be the problem?

[@technoreview85]

Adjust the sensor preset

[@Techyshashi]

Sir can use I2c module for the display

[@technoreview85]

Yes..but need some edits in code

Can I use a 100K potentiometer ?

Ye project kitne ko milega

Please you did not add the female header pins

[@shaileshainchwar6965]

Can I use MQ 2

[@partner_i_n_a_crime7748]

to make one how much did you invest

[@marsel520]

I have done this project but it is only detecting the smoke but not detecting any lighter gas or LPG GAS what to do now.

[@technoreview85]

Problem is in the senor. Please check mq6 or not

[@marsel520]

I am using MQ2 gas sensor

[@technoreview85]

Mq2 also is a LPG gas sensor. Make sure you have sufficient power source. It will be warm up before work otherwise maybe it is faulty

[@marsel520]

@@technoreview85 If the sensor was fault then it would not have detected smoke but it is detecting smoke .

[@mini_xol]

Why should we add code to arduino nano.. can't we directly use power Please reply me sir I have to present it by tomorrow

[@technoreview85]

This circuit working with an Arduino so you have to program it. An another gas leakage easy project has in this channel which no need programming

Where is female header pins???

Can we use arduino uno in this ?

[@technoreview85]

Yes you can...

Brother do you have synopsis document

Arduino Nano..

Check board, proper port. If you are using a nano then select old bootloader

Bro is it detect smoke?

[@technoreview85]

Yes it detects but the ir smoke sensor will better than it.

Instead of perfboard can we use breadboard sir

[@technoreview85]

Sure....

Can you show the explanation

bro , I will don't understand to how to give the supply of 9v in this project ?? please help me

Connect + 9v to vin pin of Arduino & - to GND pin of Arduino

show how you connect the pins it became very helpful
