Do you have any models of pH modules compatible with ESP32?
Morning everyone,
For my project, I am trying to interface a pH module with an ESP32. The module is the PH4502C. I am able to get somewhat coherent measurements, but there are quite a few variations in them, such as it goes from 7.90 to 8.16, for example, and then returns to around 7.90.
Could adding a voltage isolator card solve this problem?
Otherwise, do you have any models of pH modules compatible with ESP32?
Thanks.

Hi Joseph! Thanks for the link! I checked it out. I will try several sensors before making my choice for my project.
