Hello,

I want to know how accurate this turbidity sensor. According to my experience, he is quickly changing.
In addition, it doesn't give me 4.2 voltage in clear water. Maybe I have to open it and adjust the trimmer.
Please tell me your experiences.

Thank you in advance,

Hi! May I ask what controller are you using? The turbidity sensor outputs analog quantity. It is recommended to use the ads module when connected to esp32.
