Arduino Air Quality Sensor Tutorial With WiFi

[@RafaelAviles-pv2wl]

I can't put the thingspeak code because it only tells me to put my setup code to run once.

[@thisisforchess]

where can i see on think speak?

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

[@owenrobbin7844]

Can you make one with lcd and buzer showing the detected gas

[@mrs.karimalah4121]

Can you please provide the code for co2

[@nieuwegeljo5645]

Excellent video for which THSNKS! What I am wondering about is how to get this sensor set up in a more permanent configuration so that it can be moved. Your advice is much appreciated.

[@GoGreenPost]

You could try soldering

[@manan1298]

I couldn't find co2 in the mq135 datasheet anywhere.

Hi, where's the reading of the AQ sensor? Can your gas sensor differentiate between the types of gases and give their individual levels? If not, how does one add extra gas sensors to this setup? Can you also make a video on that? Also how is the whole thing powered? Surely it's not connected to the computer the whole time for the readings right? Are you using a 5V battery too? Sorry for these questions, this is going to be my first time building something with Arduino

[@GoGreenPost]

Hey! The reading is sent to a site called thing speak. This allows you to view the readings anywhere you have Internet access. The sensor cannot differentiate between different gases so I used this one which gives you an overall snapshot of air quality. It’s important to measure the entire air quality rather than just one or two gases. To power it I plug it in to a wall outlet but you could use a 9 V battery. The battery does drain quickly though so it wall outlet is more useful. Are you able to access the article in the description?

can i use Bluetooth rather wi-fi ?

[@thopbgm38]

for me code is successfully compiled and uploaded into esp8266 module But i am unable to connect to my mobile hotspot I have given the credentials correctly. Could anyone pls help me regarding this.

Can I add dht11 sensor to this?

[@bigsummer6661]

Hello sir Can I use a "Digital PWM UNO" for this project? And still programme it? Please reply😢

[@demonchild1167]

If I use esp8266 wifi module. I need to remove the removable chips from arduino to program it?

[@GoGreenPost]

Yes, you need to remove the chip so that you can program the wifi chip. If you’re not using the wifi chip and are just using a digital display than I don’t think you need to remove it.

[@demonchild1167]

@@GoGreenPostokay thanks for reply. But I dont know where to connect wires in esp8266

[@GoGreenPost]

It’s in the video at some point. You may need a small adaptor to connect all the wires properly

[@demonchild1167]

@@GoGreenPost my wifi module is new NodemCU V3. I dont have any idea how to connect the wires, because my wifi module is different in what you have in your video

[@miner_25]

Nope just jump reset to ground so you will be able to access the esp ! 🙂

[@sharp598]

Is the url for additional board manager broken?

[@arwinneilrubia]

Hi, there are no code from your link, do you have any link?

[@GoGreenPost]

The site is currently under development and will hopefully be back up soon!

[@BrennerEraFan]

Is it possible to make an air quality sensor using Arduino that is compatible with Alexa?

[@singletonset9804]

How can we add noise sensor Plz reply

[@aminkhaled7284]

Hi, in the code you say #include "ThinkSpeak , but in fact it is ThingSpeak

[@GoGreenPost]

Thank you for catching that!

[@denise4ever242]

Can ESP 32 module be used instead of ESP8266 module? Also can I connect Esp32 to arduino uno?

[@andylane2573]

Hi, Great video! Is this possible if the Arduino doesn't have a removable chip? Neither of my UNO's or Mega have removable chips :(

[@jay.rhoden]

If you can't afford a one of the more expensive genuine arduino uno boards with removable chips, there are much cheaper knock off clones that you might be able to afford.

[@MIZANI-dn9kk]

Hello, can you show me the reading result at the ThingSpeak please ? Because I want to make my Final Year Project. May I take your idea ? THANK YOU SO MUCH

[@GoGreenPost]

You can certainly recreate this project! My meter is no longer connected though. If you need help or want the old data send me an email at [e-mail]. Best of luck!

[@thopbgm38]

bro for me code is succesfully uploaded to esp8266 but it is not connecting to my hotspot could you please help it is urgent

[@SarahMezrigui]

Can u post the code sir

[@Xsaryo]

Hi, for some reasons I can't see the code, do you have the code posted somewhere else, like google drive?

[@GoGreenPost]

Hey - sorry about that. I updated the link. Try this out and let me know how it goes! thegogreenpost.com/2021/06/01/arduino-wifi-air-quality-gas-sensor-tutorial/

[@venkatavardhans2685]

Amazing project , Can i get the code for this please
