So the smoke needs to touch the sensor in order to react....so for that to happen I need to add fan so the sensor can detect smoke or gas fast...so we can take necessary precautions.......
These sensors are not so powerful to detect from far so the gas/smoke need to touch the sensor about the fan It will be much hard to do without arduino because if you want to do this you need relay and many things and I think if you add fan the smoke and gas will be blowed by fan so for that the sensor never detect. Thanks for Comment Stay With Us 😊
@@ShuvosProjectsSTS I meant that if we blow the air by using fan to the sensor and if I can control the rotation of the fan than it should work....also thank you for the reply....
Can u provide the circuit diag plz?
circuit diagram pls
In which pin of sensor we have to connect buzzer
Wanted to ask, is there a way to make the MQ2 sensor become horizontal? in order for it to fit in my CAD design.
Sorry I Don't know If it possible or not
Without a circuit diagram how can do this
Please , I want to ask .
Can I use MQ2 sensor for smoke?
Or only gas ??
If only gas , what is use for smoke ?
You can use both. MQ2 can detect Both. Thanks FOR comment ❤️
what is the voltage of buzzer
5V

you can try it if you want. All the best
Can I use mq 135???
Search on Internet that if mq135 can detect gas or smoke or not
Solid wire or stranded wire
Standarded wire
Ye to smoke sensor hua na?
Yes but also detect gas
9 volt battery use kry tu chalay ga?
Nahh. This sensor work with 5V
Can i use 9 v buzzer
Noo
@ShuvosProjectsSTS ok thanks
Hello, the buzzer is active or passive?
Active sir
Circuit daigram bro
Please try to make from watching the video
Will 9 volt battery work for this
No the module will burn
So is that the reason the project is not working for me?
Thank you😊
Probably yes. Check your module is it working or not if is not then you need to buy one and use 3.7 volt battery. Hopefully you understand ❤️
Ok thank u so much and another question did u use 5v buzzer?
I used mq6 and it works 🥳🥳
I'm glad to hear you did it.
Stay With us
Thank You ❤️
Can we use light instead a buzzer
Yess
@@ShuvosProjectsSTS but sir I used it but light is not turning off it's always stays on can you help please
Adjust your sensor and I will say watch THIS video here I used led : th-cam.com/video/nS6-zdRj1_E/w-d-xo.html
@@ShuvosProjectsSTS I have mq2 can I use that ?
I did exactly like you than also it's always on light
this is smoke sensor not is a gas sensor
But it can detect smoke
It depends on the gas. It certainly detects butane gas.
Yes
Bro coding...
In this project we Didn't used microcontroller so we don’t need coding
