Much better than my teacher, she asks us for projects in a short time and then leaves for a week without teaching us anything and expects us to know everything.

You made it look so easy that I wonder how hard it was for him to explain it to us anyway.

#include <DHT.h>
DHT dht(26, DHT11);

void setup() {
dht.begin();
delay(2000);
Serial.begin(115200);
}

void loop() {
float temp = dht.readTemperature();
float humidity = dht.readHumidity();
Serial.print("Temp: ");
Serial.print(temp);
Serial.print(" C ");
Serial.print("Humidity: ");
Serial.print(humidity);
Serial.println(" % ");
delay(2000);

}

Great video!! Helped me pass my prostate exam

[DanBurgaud]

looks and sound simple to understand.
thanks!

Excellent, finally a good tutorial about this. Thanks.

This is an awesome tutorial. I see you are not using a resistor on your signal pin. I have one of these working successfully with an ESP32 but when I tried using an ESP32-S2 it acts just like it's not present. I'm using a resistor on the signal pin.

Very simple and well explained, Thank You

Hro what app are u using to show dht11 commected to esp32?

[irfanudinnoranwar]

i used dht 22 and managed to get the reading for my three sensor. But the last dht22 gave me nan celsius and ann humidity. How to solve this?

[eagleeyegps]

Hello, Thank you for your video
i am looking for the circuit which can operate motor on/off with humidity and temperature sensor
Please help me

[luisfelipeonellipini]

Hi, someone knows what is the maximum area i can use this sensor?

[clerciomarchinhak]

I'll try using your video, as I have an ESP32 S3 board and an INA219 current sensor and using PlatformIO in VSCode and I can't see the current values. It only says `Talk is running`, which means it is reading, executing but the current values do not appear on the terminal. If you can give me a tip I would appreciate it! Or if I had a video from someone even better?

Hello, thank you for video, but you don't show how to install driver for ESP32 and how you installed ESP32 in 'Broad Manager'

[susmitadey]

Why my output is like this?
o/p:
TEMP: nan C
Humidity: nan%
Please help me out.

Iam struggling for 1 week for my temp project still I cannot manage

[sanabouhaha]

hello, when i compile it says failed uploading. i pressed the boot button and the enable one but still the same problem.
what can i do please?

[brianandresaragonzabala]

deben instalar una libreria mas aparte de la que mencionan en el video la libreria es :Adafruit Unified Sensor

[lizexi]

why do i keep getting nan? i have arduino nano iot 33
