- MQ 2 Gas Sensor
Detect the presence of flamable gases like
Methane, Butane, Propane, Alcohol etc.
Here in this project gas sensor
detect the presence of flamable gas in surrounding
if the level of gas goes beyond the threshold
value which is preset in code the Red LED
start glow and buzzer is activate and in safe condition
green LED is glowing and buzzer is deactivate

exactly what I have been looking for. thumbs up
What if it contains short-circuit it hase any fuse or any circuit breaker that automatically break the circuit and avoid any blasting
you could have used a pro mini which would be efficient for these kind of projects.
but nano fits better on the breadboard. pro mini is an option though if you want it to be as small as possible.
I wanted to build it with esp32 same code for it also?
BRo I need circuit diagram . ..and how to set continued alarem....
What software did you use
dear sir, we can do with ardunio uno plz tell me fast because idont have more time
Bro what are you upload in the Aurdino
what distance can it to detect gas?
2cm
What is the Max Range, do we have to place it on top of Gas Stove?
how did the sensor still working after uploading the sketch ?
Tell me where to gix the buzzer
Sir iski coding kaise ki hai aapne
You are doing so fast
Help me fast .... in which point we fix the buzzer in bread board
How long can it last with the battery?
how to make a customise speaker which speaks out some music when there is a gas
sir we can set motor insted of buzzer
I am new to arduino ... pls tell me where to set the buzzer
not getting power in mq2 why?
Sir pls can u send the circuit diagram pls
Please can u make me clear about circuit diagram
Help me my science competition is on 4th december 2018
What kind of buzzer is that?
please send link of sketches of ourdino software of this project
pls help me how to make a codes of arduino that can detect the smell of alcohol
can it detect smoke pls tell me
Can v use MQ135
parts list pls!! thanks!!
it is a bad idea to test that kind of project in the kitchen using GLP , somebody could get hurts.
Sir, how if we put lcd 16 x 2 in this project? Can you tell me?
Did u get. I also wanna know.
does it need to be pre heat first?
Yep, in datasheet (depends on model) specifies that it requires at least 24 hours to get the correct value (in case you want it in a display or some software). But for this project isn't necessary a pre-heat.
unable to see were you place the buzzer
Is that works on mq6
i am not able to get the code dumped into the nano
Brother the code is wrong can you correct
absolute fail on the breadboard, resistors for the led's are pointless. back to circuit board school..
??
as the breadboard runs in strips, the way you place the resistors makes them pointless. the circuit diagram you show is good but at 1:58 when you place them in the board is the problem
ohh yes yes u r right, thanks to point this out
