Welcome to the forum
I suggest that you use Google translate to convert your questions to English and post the translated question here
You can then translate the replies to your native language
Start by explaining in full what the problem is
λ¬Έμ κ° λ¬΄μμΈμ§ μμΈν μ€λͺ νλ©΄μ μμνμΈμ.
Is that the right language for you ?
yes ty ill try
The boss is correct, because the sensors are fake. They just make up numbers. It is impossible to measure soil NPK content with just a couple of metal prongs.
To measure NPK content, take soil samples to a testing laboratory.
so u mean problem is sensor. not a arduino? ty for information. ty
