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?
Well can you guide me about the connection of LCD with arduino to display the temperature detected by sensor on LCD in this circuit on breadboard to make the project portable.
What I don't understand is, if the Nano is 3.3V logic and you power the sensor with 5V, doesn't it fry the board? . . . will the data pin output 5V signal?
wait the analog is testing ambient air temp digital is testing the desktop temp. The desktop is absorbing the heat from the light so it will be hotter than the air. first law of thermodynamic.. I think... I can't remember any more..
The reason why you don't need a pull up resistor is that the Arduino has internal pull ups when using the data pin as an input.

And source code for arduino

Ah, finally found GreatScott's first channel
I'm afraid, you still have to search for it. I'm not him. But I'm thrilled that you compare me to him :-D.
@@nenioc187 Good content for sure, I was just clowning around because of the accent and your handwriting is surprisingly similar :P

Forgot to tell us if VCC is 5v or 3.33v or both...
Usually the dht22 works with 3.3V and with 5V.
well done
Thanks!
Thx, cool
