@IoTLearner Sir I have not used the leds yet, when I tried to start the system, the lcd was not working (it was just lit up, no words were on it) is it because I didn't used the leds or my lcd display is not working?
Yes, since it is a analog sensor... you need a threshold value, check the "Finding the threshold value" lastminuteengineers.com/mq2-gas-senser-arduino-tutorial/
Can you suggest learning material or video on how ifttt and click send api request work? I don't know enough when it comes to arduino projects. Thank youu❤️
Hi sir, can I use sim800L instead of sim900A
does this work with gsm sim900 mini?
Hello, I hope you are well. I have a problem, my LCD screen does not show me anything, what can I do?
Excellent

Sir i have a question.
When i remove the ground or vcc wire from whole connection every thing will be high smoke,gass etc
Plz tell me why its happend?
is there any 3D software solution(tinker cad) for this
Thanks for sharing this. Please could you help with the link to the LiquidCrystal_I2C library that you used in this project
???
I’m getting an compilation error: Liquidcrystal_I2C.h : No such file or directory
Import the lcd library
where is the breadboard in the circuit diagram
hlo can i use gsm 900a instead of 900???
yes
Do I have to change programming by using 900a?
WHERE I GONNA BUY SIM 900 GSM SAME WITH YOU ?
Bhaiya aa ab youtube pr videos kyu nahi dal rahe ho
My lcd don't display anything
what program/site did you use for circuit diagram?
Its called fritzing. Its a free software
@@IoTLearner I can't find some sensors on that software. Can you give me the fritzing file of that diagram? Thankyou
Hi sir what can i do if the software serial not found?
Can I use Arduino wifi instead of GSM module?
And how this change will affect my project code
You have to make a Http api call from the arduino code to services like clicksend/ Ifttt for sending sms
Why my gsm module can't recieve message from the alarm
Most probably, your gsm module is not connected to the sim network. Check if the led of your gsm module is blinking with a delay
Hello sir
Can we use the MQ5 Gass sensor instead of MQ2 Gass sensor?
Yes, since it is a analog sensor... you need a threshold value, check the "Finding the threshold value" lastminuteengineers.com/mq2-gas-senser-arduino-tutorial/
can i use arduino nano and gsm 800L
Helo sir, can you make a coding for Flame and Gas Sensor as a Input. Led and Buzzer as a Output?? Can you make a coding and post on youtube?
Is GSM module supports for 4G sim
Yes it do supports 4G,
Use a WiFi Module please. I need a WiFi module tutorial for a school project
What is the source of power supply in this project Sir? Thanks!
I'm giving power supply to Arduino and Sim 900 using the 9V dc adapters.
@@IoTLearner Good day Sir! how can i fix the error about software serial not found? Thanks!
what is the library of this code sir?
How can I replace sending a alert message using wifi instead of gsm module?
You can replace gsm code with ifttt (if webhook then sms) or clicksend sms api request in the code code
Can you suggest learning material or video on how ifttt and click send api request work? I don't know enough when it comes to arduino projects. Thank youu❤️
@@johnvincentsuarez5573 check this for ifttt approach: ruclips.net/video/Ek57tecFd_Y/видео.html
@@IoTLearner Thank you so much💯
Hi I have copied same code
lcd.init(); on this line it shows error
please assist me with the code
HI, can i use the MQ 4 gas sensor?
Yes you can simply replace it with MQ-2 as pin mapping is same
@@IoTLearner Hello, I don't have the module to send the message, can I skip it?
@@julianatehortua sure
@@IoTLearner thanks
Can we talk inbox?
Hiii bro
