- In this tutorial we will learn how to use the DHT11 or the DHT22 sensor for measuring temperature and humidity. And we will see the value output of the DHT sensors on both the serial monitor and the LCD screen.The LCD screen component is optional. With this tutorial you can also print on a serial monitor. Code and circuit diagram are compatible within both sensors.
Required Hardware:
Arduino Board :
goo.gl/Rqc5w2
amzn.to/2LZr6t4
DHT11:
goo.gl/n9qv8K
amzn.to/39qXnC6
DHT22:
goo.gl/W5Qo9p
amzn.to/31tNK13
LCD Display:
goo.gl/SxH8Jx
amzn.to/3bbBgzu
Potentiometer:
goo.gl/MPwcEM
amzn.to/3dlgYq1
Breadboard :
goo.gl/GjpqVW
amzn.to/3qxLxwm
Jumper Wires
amzn.to/3doetmT

The DHT sensors have four pins, VCC, GND, data pin and a not connected pin which has no usage.
From left to right:
1 - VCC (5V)
2 - Signal
3 - NC Not connected
4 - GND

thanks Mr.Mert ,previously I have problems with this module, your video fixed it
Thank you so much. Your project helped me a lot. Keep doing Various Arduino based projects. :)
Hello,
that it a error message : "no matching function call to 'DHT::DHT()'
Me gusto mucho el vídeo, Saludos desde México
Great tutorial any chance of a follow up showing how to add a fan controlled by this setup?
Hello . Thank you for your wonderful explanation.
I have a question:
Are the sensors like LM35 and DH11-22 accurate and reliable?
Are it need to calibrate?
thank you
❤️❤️❤️❤️good work ❤️❤️
wow it's very helpfull thanks, btw what app do u use to draw that chart ?
do we have any other better product for accurate than dht 22 for audrino uno?
brocum lcd ekrandan o pinleri hangi aparatla aldın bi söylersen
thx for all your videos they helped me i lot and wanna ask for help "how can i send data sensor's to excel "
Hello,
I am having a problem with my setup: I have connected a DHT11 to an Arduino Nano (properly, I think, resistor included. It actually worked the first day, so...). Anyway, I am getting zero values of temperature and humidity, no matter which library I use. The sensor is detected correctly, but the data is always zero. As I said, it worked the first day I tried, using Arduino's DHT example. Not any more. I don't think I have changed any library version. I tried with previous ones and it doesn't work either.
Can anyone help? Thank you!

Any idea how to get it to show Fahrenheit on the LCD?
May you give me an example for a touch screen display, if you have time?
1.sorum direnç değeri nedir okuyamadım
2.sorum program internette yazdigin source codu ise ekranda tek çizgi çıkıyor
Very helpful video. I want to know 1 thing that, if i want to glow an LED when temperature goes above than 40 degree. Can you please send me the code for it?
what software do you use for diagrams?
Where did you create the fritzing diagram?
why does the data line need to be high? doesnt the module already get the power supply from the +5V pin?
can u pls make a video using i2c and lcd and dth11 pls
nice
fantastic
Can you create tutorial for temperature alarm?
Abi direnç değerini yazabilirmisin
Üstadım çok güzel bir çalışma olmuş sorum olacaktı
what is the value of the resistor that have been used on the DHT11
10k
And please this
DHT11:14:24: error: no matching function for call to 'DHT::DHT(int, const char [6])'
Can you please help!!!!!
Error saying - "DHT11 is not declared in the scope"
Your efforts will be highly appreciated
HOW CAN I FIND THE DHT11 SENSORS IN TINKERCAD?
my lcd shows -999 for both the value. Whats wrong with it? i have already checked the connections. Can you help ?
thank you
copy and paste "How to Set Up the DHT11 Humidity Sensor on the arduino" in your search and try Circuit Basics video and pin out, and sketch.
i have a problem.....lcd display not showing in this value......why
Every other time it shows -999 instead of temperature. What should I do?

Thanks so much I was so frustrated how to download this library thanks
On the back of my LCD there is 4 pins GND, VCC, SDA, and SCL. do i just use the pins you showed in the video.
No. What you have is an "I2C"-interface on your LCD. Google it for info on how to connect and use it.
schade das der Link nicht funktioniert...
😊
Why this library doesnt work? i tryed like 2 weeks to run stupid humidity and temperature sensor and i am frustrated... No example works and i cant compile anything... please help... its like this library doest have any of these functions i tryed to find it on github but nothing... no trace of these funcions. and i am not the only one...
here is the error from example:

i tryed SimpleDHT library but its just for DHT11 but it works...
first comment :D
Can you please do an RFID tutorial
Thank you :-)
kardeşim neden türkçe kaynak yapmıyorsun hem iyi bir kaynak olurdu ha illa yabancı da yapmak istersen ing alt yazı koyarsın
plaese code DHT22 Sensor Using with Arduino with fan
sang name pls 😊
Abi sen türkmüsün
Abi bunun Türkçe halini yapar mısın kanalının kalitesi çok iyi abone oldum kanalında ayrıca her videonun türkçesini yaparsan abonen artacak 'BURALAR DEĞERLENİR' benden söylemesin .şimdiden teşekkürler
