Out of every Arduino tutorial out there, from every site across the board - and I've been to em all (or so it feels like, it's a lot!!) - you are BY FAR, the best at explaining things. Thank you so much and please carry on :))

[dr_akoto]

THIS IS MY SUCCESSFUL PRACTICAL TUTORIAL...THANKS ROBOJAX

[projardgreen]

explain more videos like this, the code in detail, I subscribed because of how detailed explenation was.

[ronnytoro]

Awesome page ! thanks for all your advices and information that you share!

[danmusiceasy]

Great tutorial, very clearly explained! I just made my first air monitor :) Do you have any tutorials on particle sensors and VOC sensors, or plan to do any in the future?

[tonysicily]

Awesome video,
No music
Clean video
Nice VO

Lots of info

Thank you,

as always I love watching your videos, how do handle negative temp. what changes do you have make in the code ?

[truthseeker]

Thank you so much Robojax. What a great video. I wish you had continued on to tell us how to write the code so that the sensor could turn on or turn off a light or motor when the temperature reached or declined to a certain

Thank you very much !! I have a question. Do you know the difference between the Temperature value and the Heat index value ? Which one is more accurate ?

[fatimamgaedeh]

Hello, great video and tutorial. My question is, when I have to use a resistor?
So, if I want to connect 4 dht22 sensors together when I need a resistor?

[JohnWick-idpk]

Hi, thank you for the informative video. What do you think would be the cheapest cable tu use the sensor at 3 meters from Raspberry ? Thanks

[jamesdumancas]

Hi sir thanks for this helpful video i just wanna ask if the dht 22 can go faster than every 2 seconds loop?

[fpt]

Hello . Thank you for your nice video .
I have a question:
Are the sensors like LM35 and DH11-22 accurate and reliable?
Are it need to calibrate?
thank you

[patrickduhirwenzivugira]

Thank you for the video. Any idea how I can add a wifi module and send the data read as REST API ?

[alialvi]

kindly tell me that while you run DHT tester, your uno borad is connected or not?

[gamestv]

Good tutorial.Worked flawlessly.
Thanks

[michaelmotis]

Thank you bro!! good job! it does work for me

[jasperblase]

I know this is a bit of late but when I see the humidity readings on your video, it's very low. Is your room dry or just error from the sensor?

[iamrrebel]

Please I would like to know if this temperature sensor can work on poultry farms. Thank you

The DHT22 sensor enables temperature measurement in the range of -40 to 80°Celsius
Does your program accept this? I.e it also shows negative temperatures?
