A very informative and detailed video done.
And this is true, most of the youtube videos have made without conversation of values and calibration of sensor.
And also I liked idea of using Mux with NodeMCU.
Thank you..
Excellent Video.
Wonderful, Clear and Bold explanation.
Keep up the good content. A Big Thumbs up!

this video has given me a great support
this video was very informative. nicely done mate
Awesome video ! Thanks from Belgium !
Thank you for publishing your video. From my reading of the MQ7 data sheet, it requires a heating cycle and then a cooler read cycle. A few folks have schematics and code published on the web. I've not calibrated my mq 7 with known values yet, so I can't say they really work. The data sheet also recommends a 48 hour plug in before using.
Yeah.. You are right.. Datasheet recommends to keep it for 48Hours..in fresh air or inside a room.. Use the code MQ7_1 in the zip folder 📂 available In description below.. But I did it for only a few hours.. No probs..

Thank you @Bharath Kinnera for the links you have shared. I have been searching for the calibration part for so many days. But couldn't find any detail explanation. Thanks for your help.🙂
You were very helpful dude.
Thanks for sharing knowledge
Thanks for the information, very clear explanation.
Hello, thank you very much for your research, it's a great contribution! I have a question: the datasheet of MQ-7 recommends applying a heating cycle of 5V for 60 seconds and 1.4V for 90 seconds. What is the impact of not applying this cycle? Your research doesn't include this cycle, so how could it affect the procedure?
Bro this video is so good!
You have explained it nicely.

Hello Sir i have the question about R0 from MQ7, in the code you wrote R0 of air is 27. How to calculate 27 which comes from graph in datasheet of MQ7? Since I'm having trouble determining the number 27, can you please explain if there is an application to get the number 27. Thank you.
shesh your video is very2 detailed. I really like it, here's a like from me
Superb,thanks for sharing
Thanks Brother, it was of great help for my project

Thank you Bharath ! DO I need to load libraries first before uploading the sketch on the Arduino Uno board?
ruclips.net/video/R5vO9HKKJ60/видео.html
I some to do this project but first im not understand the situation I gave to me they want to determine the present gases and shows what value it is. You may help me for to do that.
well explained. useful
Very good and describe clearly.
Well done.

@@AKElectroTech brother, thanks a lot. My team made it, this project with very much update sensors and hardware in low cost. But thanks u again i got a good view in your videos. So carry on and best wishes to you. Assalamualikum
good job, well done.
which is the dependent variable and independent variable in this case
Hi great video, God bless you , to attain a great position if not already.
Why did you select RL as 10 to calculate Rs?
Very good explanation sir.
Can you please provide the website link that you mentioned at the end of the video. Please reply
In my school phone and laptop is not allowed so while doing the project is anything needed?? Like u wanna connect it to a phone or laptop ...what if we don't connect it with any device ?? Will it work or not
Great job bro
Thank you so much 👍
Bro,Am using ESP32 DEVKIT V1.can you tell how to connect it with MQ 135 and 7 plz.I tried a lot but failed each time
I have one question. Why you assume 10 like the value of Rl on the arduino sketch? I think that the value from Rl is 2Kohms because on my pcb are connected a resistance with that value on the pins B from the sensor and gnd from the board, just like the datasheet from mq-135. So, the table to calculate ppm with rs/ro its thinking with an 20kOhm Rl. However, thanks for do this great project
ruclips.net/video/R5vO9HKKJ60/видео.html
can we use Arduino
with wifi ESP8266
(WEMOS d1 & r1)
instead arduino uno or mega
How can I understand the resistance load value ? Is it 10k for all
Brilliant
Fabolous
Well explained
Thanks for clear explanation.. I have one doubt.. what is the threshold value for mq135 sensor ppm value.. i detect and alert other gas value increases?
ruclips.net/video/R5vO9HKKJ60/видео.html
i dont understand where is the main program to run for mq135, idont understand what is calibration is used for?
But how did you calibrated your sensor?
how to calibrate these different gas sensors??..because we have to calibrate the sensors first before getting the data from these sensors...??what is method of the calibration of sensor??kindly reply me..i am waiting
What are user requirements and non-functional requirements for this system??
Thanku 🫂
Kudos
Bhai mujhe connection Mai problem a rahi hai
And I want to use uno, MQ 135&7 SENSORS ONLY can you help for connecting and pushing to cloud
thankyou so much
Bhai ye project me future ka prediction apply kar sakte hai ki nahi
amazing video! I am working on the same platform(project) in iit delhi brother

bro which year u r studying in vit and which branch
my MQ 135 sensor is not showing green light only show red light its proper or damage?
Thankyou indian guy❤
Can this also work on 16 bit microcontroller?
Crystal clear voice🔊
Kinnera sai version 3.0
Thank you da!
Sir instead of sending the message to cloud how present in 16×2 LCD display
Very good
thanks you bro
Please help my wifi module is not connecting to the wifi network near it what to do I tried changing the hardware also bought new module but still no luck
MQ-7 WHAT DID YOUR USE FOR?? MQ-135 CO BUT MQ-7
boy i have open the link of folder but it is asking for decryption key...kindly guide me plz
Thank you so much for sharing this video. I have a final project and i have been thinking how the calibration can be solved. With tihs video, I will be able to see my path easily
hlw brother.i want to talk to you about this project
@@ADSMASH sure. How can i help you?
@@akncaglayan9494 i want to do this project in my final year .can you give me project related all information.i am interested to doing this project
@@akncaglayan9494 Sir, can i get the simulation results from you?its very urgented .please help.
@Akm hello brother..kindly can you tell me the method of the calibration of these gas sensor??..i am stuck at this point of calibrating the gas sensor..kindly reply me..
Very informative video and thank you very much... i have a small doubt please clear this for me... in the mq7 calibration part of yours to get the R0 value you have divided RS by 27 (RO=RS/27)... which means RS/RO=27 ......... but when i go through the the data sheet of mq7 the fresh air ratio is around 9.6 that is RS/R0=9.6 ...... please be kind to let me know about this...
the value of RS/RO for fresh air could be found in the graph, so check the datasheet for graph
ruclips.net/video/R5vO9HKKJ60/видео.html
can the mq135 detect co2 upto 2000 PPM?
can i get final program code of this project, its urgetn. It would be great if you share it. I tried to run your given program but facing lot of errors, i tried to solve evrything but dht 11 sensor giving me lot of trouble.
👍
Very nicely explained...one small clarification...can you tell what specific gas you have measured here using MQ 135...bcz my thesis is to measure CO and benzene...so can we program the sensor to measure benzene alone...I am a postgraduate dentist student...so can you explain please...
Or else is there a electrochemical sensor for measurement of benzene alone
ruclips.net/video/R5vO9HKKJ60/видео.html
Can I get the exact steps to do this project?
You explanation is just nice..But I have a que that you get AQI as 0.49 then at that time what is the value of real AQI in your surrounding ? And
0.49 is stands for ppm in percentage right?
When I done it real AQI Is showing 51 and I get final percentage the value as 0.49%
So is it right or not?

Thank you can I use mine site environmental monitoring. Please reply me.
How much this project cost around??
Thank you sir but I want to know that what I can do to detect only the ammonia gas
Use ammonia sensor mq137
I want a sensor only for CO2 running on arduino, what is your recommendation my friend?
I dont think about a sensor only for a particular gas.

how to find b and m, which you have mentioned in MQ7_2 and MQ135_2?
see his published paper you will find the way to calculate b and m
This project is awesome.. :)
I really liked it.
And one thing is that i also start work on it..
Do you have a report of this project
ruclips.net/video/R5vO9HKKJ60/видео.html
how can i use the code with arduino uno not mega?
can you make video about that nodemcu and multiplexer sir.? how many need multiplexer if i want use 3 sensor.?
Sorry I can't make a video on it
You can make use of Ads1115 multiplexer with nodemcu and I believe you can easily get the code for it.. Just do a little big search
Can You Please Give Me The Diagram Of Serial Connection Between Ardunio And Sensor ? Reply Asap !
sir how long to calibration the sensor to get nice output.?
Did you find out how? If so pls help
Bro i need your help. I am facing a bit problem. I am from Pakistan and want to talk to you about this project kindly help me
Bro!! Can you code for food monitoring system using aurdino uno, dht11, wifi module, mq3 sensor and send the code to this mail id
hey , i m doing my project on air quality monitoring and i m using multiple gas sensor mq2 ,5 ,135 .
i am confuse that can't we sense a particular gas concentration using this sensors , some of the youtube video showing different gas ppm conc. please help me out if we can calculate particular gas value then how
Say for eg: MQ135 sensor goes high if *any of the gases* concentration goes high.
Using mq series sensors, you can't particularly measure a gas. I'm not so sure to tell you about particular gas concentration measurement
As of now, if you take mq7, it's primarily for CO, but it also goes high for smoke or other gases as per datasheet. You can take mq7 and claim the output as CO concentration, but strictly it may not be correct

hi, Very informative video. How do I contact you? I have made an Air purifier and want to show the air quality of the room also, This device is helpful for me. I need some suggestion from you.
What kind of suggestion you need?
Hello, thanks for the video. Please I need help connecting my raspberry pi to MQ135 including MCP3008 ADC.
Sorry that I haven't made use of raspberry pi.. I believe arduino is sufficient to make use of these sensors as raspberry is costlier
nice work..could you please share code of python with raspberry pi, please.
Bro I need circuit diagram for this project
bro can u pls make the video of how to make the model
What sensor did u used to get air quality?
is there any computation?
