How to connect solr charger connector, solid copper wire, solar panel and powerbank? For air quality monitoring system.
sir i have a doubt, the gnd of esp is connected to the +ve rail whereas gnd of dht11 is conn to -ve rail, from what i have heard that gnd should always be connected to the -ve rail of the breadboard and vcc/vu to +ve rail so sir can please clarify on the circuit diagram in this video
Exactly which I2C converter we should needed
Can this done as final year project for mechanical engineering students?
Please check the project title with your faculties and get approval before starting the project.
Iot are for cse IT students
can this be done as final year project for IT student? what AI features or machine learning can I add to it to automate it more
Yes you can do. I haven't tried AI.
shameer bhai big fan pls give password we kids from kendriya vidyalaya we dont know paasswoerds pls help us poor kids
May I know which password you need?
i 'm using 2 different mq135 but readings are 750+ on both sensors (room and outdoor same results) whats the problem?

Does this send you notification quickly, when it detects bad air quality? Please answer🙏🏻 thank you!
Sir can u make the detailed video about the code and connection or can u explain it in comment section
Ok
Can we also use dht 22 sensor instead of dht11
Yes. two lines of code change will be there.
Sir did u know jow to replace it to lcd TFT
I haven't tried.
Why my lcd doesn't show the text sir??
Check this video ruclips.net/video/ElmLKC2giQ8/видео.html
how to find template id and template name also auth token on blynk?
Are you using male to female wires?
Yes.
Male to Female (For Breadboard to Sensor Connection) and
Female to Female (For I2C to Sensor Connection)
@@TechTrendsShameer By the way I tried to make the circuit diagram in Fritzing but I didn't find the library for MQ135, do you think you can help me with that?
Can u give the code
Check video description
Sir getting error while uploading 'FileNotFounderror'no such a file or directory
Send me the full error message
U got the solution ?????
It's shows the error and blynk sampleEsp8266.h No such file or directory like this
Install the Blynk library
I2C showing warning
Install the library.
sir i need answer ASAP the code is working but the gauge in blynk is not showing the data can you show me how please😭😭😭
Check the Auth code and wifi credentials are correct.
is it okay if the lcd is with 12c at the back?
It's completely ok. You can also use in that way.
Provide the connection for interfacing of circuit
Its in the video. Watch full video.
Which IDE version you are using in this project
Arduino 1.8
How much will this project cost?
Components link provided in video description. Please check.
Sir can you please tell us how to configure arduino for this project, i.e how to get NodeMCU 1.0 board to select ESP8266 Boards (3.0.2)??
Please check this video ruclips.net/video/IXSzQpfp0n4/видео.html
@@TechTrendsShameer Thank you so much sir!
Sir please tell where did you write the code, how to upload the code to ESP8266 board
To write code I am using Arduino IDE.
Check this video for NodeMCU setup
ruclips.net/video/IXSzQpfp0n4/видео.html
@@TechTrendsShameer Thankyou sir for your response, but even after trying multiple libraries for LiquidCrystal_I2C
showing "compilation error no such file or directory is found"
sir, Please tell what should I do
May I know how you installed the library?
@@TechTrendsShameer Sir after trying your zipped file for LiquidCrysta, it worked
But now same problem is arising for (HID) but unlike other libraries I used there is not any proper library in Aurdino IDE as HID.
And even after trying a zip file from aurdino website, error is same
Sir please tell me what should I do
What is HID ?
please help there is an error that says BlynkSimpleEsp8266.h: No such file or directory
Install Blynk library.
Sir im getting error as lcd.begin() as liquidcrystal
Follow this video.
ruclips.net/video/ElmLKC2giQ8/видео.html
there are error in code. nodemcu pin to be defined as D2 and not 2. further GAS value is not getting printed in serial monitor being not defined
Both are correct. If you define as D2, you need to connect to PIN D2 in Nodemcu. If you mention as 2, then you need to connect the D4 in NodeMCU (GPIO4).
sir we are getting error as "A fatal esptool.py error occured: Write timeout" what to do
Remove the cable and connect again.
Sir i dont want to use I2C controller then it will okay or not
You need to modify the code if you are not using I2C.
hello, I need the flow chart of the circuit.
Why my arduino tools showing the Board: Arduino Uno instead of Board: Node Mcu you provided? Please help me asap, this will be my projects. I am a IT Student here!
Please check this video to setup NodeMCU
ruclips.net/video/IXSzQpfp0n4/видео.html
@@TechTrendsShameer it shows that "Error compiling for board NodeMCU 1.0 (ESP- 12E Module)" how can i fix this? i already connect my board in my laptop
please reply me asap :)@@TechTrendsShameer
I am getting Compilation error: DHT.h: No such file or directory message, what should I do ?
Install the DHT library from Arduino IDE -> Tools -> Libraries.
im getting blank display and nothing displayed in blynk plx help
Adjust the potentiometer
Nice project but if i have to use this in the open field it is not working as there is no wifi connection so pls can you make A project that works on arduino nano as it does not Requires wifi connection and can sense Air Quality anywhere without wifi or internet connection
Hey! we are also working on a similar idea that you referred, did you find any similar videos/projects related to that? Also please tell us because we are going to make it a final year project. Thanks
1 person by the name vk technology has put the project on youtube is working without wifi with ardu nano but has not put code in the discription and is asking 1000 Rs for code
It is vmk projects
It is vmk technology
Sir it showing error on #include
Install the blynk library.
Can you make me programme for arduino nano whit out esp
This program we can't do with Arduino Nano since nano board doesn't have WiFi.
why i cannot find the esp8266 in fritzinf app?
Many parts are not available. You can download from this and import in fritzing
