THANK YOU SO MUCH I was having problems, I had temperature and humidity reading 255 every time but this video solved my issues, you're a legend

Thank you for the explanation! Can you elaborate why you stored the result of the read11 function as an int "chk"? The variable doesn't appear to be used anywhere.

The chk variable is integral to the library somehow, but I'm not sure how it works. I just know that it's required because I have tried storing the sensor reads in different variables and couldn't get it to work.

Nice...

When I try to verify it, I get the error 'DHT' was not declared in this scope, how do I fix this?

Serial.print("Temperature = "); 15 Serial.println(DHT.temperature); 16 17 Serial.print("Humidity = "); 18 Serial.println(DHT.humidity); 19 20 delay(1000);

what kind of software did you use to demonstrate the usage of DHT11 humidity sensor, virtually?

@omegasm8054 29 күн бұрын

Is the Arduino serial monitor, it's already included in the Arduino IDE

Sorry, I'm not a english native speaker but Id like to ask if that reading is in C o F degrees? Thanks 😊

Why didn’t you put a link to the library video instead of making people search your channel. It’s not improving your views by making us search. Just the opposite.

Well now u can just install libraries using arduino ide by going to Tools -> Manage Libraries... -> typing DHTlib
