GAS Leakage+Smoke Detector Using Arduino + MQ2( or MQ9) + LCD SCREEN +I2C module + buzzer / Led
HTML-код
- Опубликовано: 17 авг 2024
- The Circuit uses a gaseous sensor device MQ2/MQ9 as an input device and processes it by using the Arduino uno in sending an output to the LED and Buzzer when a level of gas is detected and this level is displayed on the LCD Display

Hello what kind of jumping wire did you used?
exit status 1
'class LiquidCrystal_I2C' has no member named 'init'
marca error ayuda:(
lcd is not showing readings
I AM LOOKING FOR THE CODE PART WHERE IS IT?
How you derive the calculation to convert values into percentage
LiquidCrystal_I2C.h no such or directory . kindly help . making project for my students.
Làm ơn giúp tôi, sau khi nạp code mạch của tôi báo động liên tục ko về trạng thái bình thường
THANX BRO
Hi, i am having a compiling error...
exit status 1
'int LiquidCrystal_I2C::init()' is private within this context
I have the same problem
use "begin" instead of "init"
Bro I need code
may I have the fritzing sequence file ?
i dont have a file for running a code
i want all this file coding help me please ...
I need code
Running the program doesn't help as well.
Kindly specify the problem you encountered with the Arduino code.
Can't upload the code to my arduino
which error message did you receive?

Does it detect smoke?
Yes it does
@@josharduino3241 I have made this project but it only detect gas. What should I do to ensure it can also detect smoke?
@@damiakhalisa6951 MQ2 /MQ9 Gas sensor works on 5V DC and draws around 800mW. It can detect LPG, Smoke, Alcohol, Propane, Hydrogen, Methane and Carbon Monoxide concentrations anywhere from 200 to 10000ppm.
But incase you have a sensitivity problem,
You can calibrate your Sensor by holding the gas sensor near smoke/gas you want to detect and keep turning the potentiometer until the Red LED on the module starts glowing. Turn the screw clockwise to increase sensitivity or anticlockwise to decrease sensitivity.
@@josharduino3241 Alright sir, thank you 😊👍🏻
Corect code plz
That’s the correct code…
Kindly specify the error you got.
Help please
