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.

Hello! If you use one controller to connect two iic displays with the same address, it is recommended to use an I2C Multiplexer: https://www.dfrobot.com/product-1780.html
