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.

[@Circuitbasics]

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...

can you give me dht libarary

[@wifa45]

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.

Dude, great info, but you scare the hell outta me the way you look into the camera like that. Shudder....
