DIY Air Quality Monitor - PM2.5, CO2, VOC, Ozone, Temp & Hum Arduino Meter

It's not a product. I have inkbird's IAM-T1, a sensor from Sweden with a temperature and humidity screen and a battery that lasts four years.

can i buy the prct that you create

Great project- all put together- just can't get past error messages in arduino code related to github- anyone with a working file?

CAN DIY FOR ME? I CAN PAY FOR IT

Hi Sir can I buy the end product from you? How to order your DIY made product?

this build is so clean

A very nice project that I was very much interested in for VOC monitoring until I realized that you can actually buy an air quality monitor that covers VOC's for less than just the PM2.5 sensor in this project costs

Hello sir...is it possible to make this project wirhout ozone sensor? What will be the nextion code then can you plz help me??

Any device for monitoring water quality... Dissolved oxygen in water

looks I was little naive, when I explored Altium. Prices starting from roughly 400 bucks per month. what's that for a recommendation, it's definetly for the ordernary hobbiest (if this word even exist lol). or did I miss something on the website?

Отличное видео, спасибо за гайд друг!

Great video! As a environmental eng, I can tell you thats amazing. Low cost and very good precision. Did you comparate with a real sensor, like a industry sensor?

Do you sell this as a kit?

You say these sensors are quite accurate, have you compared them to high quality sensors?

Is it possible to record the data?

Hey Dejan,
On my monitor after is saying “Warming up sensors”, is not showing any value. Everything stay at 0.
Made sure the upload button is not on.

I don’t know what to do. Do you have an idea why is doing that?

Excellant my wishes go head

Hi Dejan,

I have a problem with the code, is giving me some errors, can you please help me?

Compilation error: no matching function for call to ‘DS3231::DS3231(const uint8_t&, const uint8_t&)’

Excellent design and build. Thanks for sharing.

hello do you considered add a radon sensor?

Great video, I made a similar system based on ESp32 without display but It can be integrated in home Assistant so you can check data also remotely

My goofy ass thinking I can make this easily 🗿

Hello there, do you sell all the items listed and support with the project build ?

Useless because they canna no speka Englis

Does anyone know what are the Altium files for? Do they also need to be uploaded to the website for ordering the PCB? The Gerber files seem enough in order to order the PCB, but I don't want to make a mistake.

Bravo 👏👏👏 . One question though 😋 i would like to send data to an api endpoint like grafana to keep track of the registered data. Any idea if this is possible?

I am interested for this project making for my FYP

Hy sir , I just want to know about the making cost

Fabulous build. Thanks for posting and for all the linked details. 💯👏

Considering how important the air is, I’m surprised none of you test your marijuana😂

Where can i find the project download link? Is it open source?

the altium design file link is broken, can you help to fix it?

Hi Dejan thanks for the amazing project
I was just asking about the Mq131 sensor, its mentioned in the datasheet that it should be preheated for 48 hours
It is also mentioned for Mq7 sensor that i want to use ? can u guide me throgh this?
Can i use the sensor straight away after purchasing or should i do the preheat procedure ? and how can i do that ?

THANKS

Hello can I ask some questions, I try to build your project, and buy the PCB to jlcpcb, I don't know why the project is not working I already uploaded the code and everything is seem ok but the TFT screen not responding to the sensor, all zero value

your a genius

can you please send the code??

Awesome video!

Congratulations for this project, I wonder if this detects dangerous gases as hydrochorich acid fumes or others, I'll appreciate your answer

brother can i use pms7003 senser module
please tell fast its an urjent

hello brother, I want to ask about the application used to create the schematic of the cable line in the picture?

please respond thank you

The PM2.5 sensor blue color is the protective film that needs to be removed

Can any of these sensors detect carbon monoxide? or I would have to add one for that?

great project, my workplace needs a few of these
is there any way to add a decibel meter to this project ?
is there a way to add a carbon monoxide sensor and monitoring?
and is there any way to have 5 of these units report back to a central device for real time monitoring and data logging ?

Hey, thanks for the superb presentation, can I get the ready made model from your side please, I can cover up the expenses as well!

Would be nice for carbon monoxide instead of dioxide

With the Screen can you use an alternative?

where I can buy the whole thing?
