DHT11 & DHT22 Sensors Temperature and Humidity Tutorial using Arduino

What if I get temperature and humidity values "-999". It happens from time to time and totally random

Where do I download the library for my DHT22?

I cant find dht.h library

can we design with an Arduino to read 2 Max6675 temperature and send the data to the computer?

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?

I am running the same code but getting an error of No such file or directory . Can you please help me with that thanks.

Thank you. That was very thorough!

can you make and DHT11 Temperature and humidity sensor using arduino with LCD display tutorial
materials needed is:
2 pieces of DHT11 sensor
1 piece of LCD 16x2 with I2C Module
and show to code for this please....

Can I use this sensor on the industry level?

if i change the delay to lower than 2000 ms, is error occure? or it gives the earlier calculation.

can u give the circuit of lcd display its so messy and i tried to understand the pin outs from picture in intro. But its to hard so pls put the fritzing circuit.

man thanks, I didn't know that dh11 doesn't support negative temps

Gracias

The content of this video is really good but you should work on your intonation. Every sentence throughout basically this entire video was said with the exact same intonation pattern and it sounds super robotic. Talk like you are having a conversation with someone, not just spouting facts. No offense intended, just a tip. Great video.

I am brand new to arduino, can you hook this and a MQ9 up to a single arduino uno? Thanks for this video.

I know most of the previous comments are 2 years old or more but I just started and like all the others it was very clear and easy to follow. Thanks for a great tutorial.

Inaccurate!

How to remember set point on power is off

It keep telling me -999% on both Humidity and Temp, what do i do ?

Hello, could you please tell me how to install dht.h?

how if that distance sensor? do you know the code?

I can see others seem to have had the error ‘ dht ‘does not name a type, but no solution seems to appear, does anyone have an answer please ?

Hi, congratulations on your video. But I get the error that "the dht.h library is missing. There are several libraries, I don't know which one to install. In my Arduino the dht sensor library is installed, but it doesn't work with this library. Any suggestions? Thanks.

Hola, felicitaciones por tu video. Pero me da error de que "no encuentra la librería dht.h HAY varias librerías, no sé cual instalar. En mi Arduino está instalada la librería dht sensor library, pero no funciona con esta librería. Alguna sugerencia? Gracias.

Excellent. Congratulations.

would you please give a PCB diagram with arduino nano.

dht.h no such file or directory..... any ideas?

wich resistor is that

thank you very much !

Outdoor DHT sensor doesnot read minus values at winter.
Please ,how can we fix the temperature from -50 to +50

hy bro
can we control incubator with it

Can you tell me exactly which library to download?
DHT only? Or the Adafruit-sensor-master as well?


sketch_oct30b:14:1: error: 'dht' does not name a type

dht DHT;

I'm just getting 0 temp and 0 humidity

This video is excellent. Educational, clear, and concise, and interesting. Thank you so much! I wish could subscribe 100 times

is your code available

Could you pls help me how to connect to cloud

Thanks so much man!

brother, I am a little bit confused here because you did not show how to contact the display to the arduino board
Please, help me with this

Can a Nano work with this? I need Nano, LCD, 2 Temp and 1 or 2 humidity

very good video. Included everything you need to know. Thank you!

How i connect lcd?

I could not get the DHT11 single wire protocol to work with a 20x4 I2C display. The display works fine with just a display sketch, and the DHT11 works fine with just a DHT11 sketch, but the two could not be carefully combined to work together. Using the serial monitor display as well as the LCD display simultaneously, I can see the sensor working properly but there is no change whatsoever to the LCD - nothing displays. I suspect that with the on-board pull-up resistor pulling the DHT11 high and ready for communication, it may have been preventing I2C from starting up. I don't know. Ideas?

hi can it work without computer after programming
reply fast

Dejan thanks for your stuff it is clearly and understandable as always! I would like to ask if you know how can l schedule two dht22 to take their measure every 2 sec, l mean to synchronized the measures at the same time (cause l need to calculate a gradient )?

im using proteus for simulation BTW. .i need DHT22 library for proteus

VERY NICE EXPLAINED, THANKYOU!

Thanks for the explanation

can you please snap an upper view of the model
i dont really know where to put the wires
