Any ideas on how to use PH-4502C pH Sensor with ESP32 I have connected live/ground and sensor wires but the ESP32 is just reporting 4095?
I can not find the DataSheet / Manual for the PH4502C.

Re: ESP32 & PH-4502C pH Sensor
Hello! I don't know if it is still in your interest to obtain information about this device, but it turns out that I recently started working with it and came across the big problem of lack of information, have you made any progress in using this sensor?
About your problem (if you still have it) it seems to be something in the esp ADC configuration,
I'm using esp-idf and it has some peculiarities that I honestly haven't been able to understand yet, but after seeing some guidelines I managed to make it work on my Xiao Esp32 C3.
All the information about this sensor that I found was related to Arduino IDE, but there are some websites that have some relevant information or another: https://cdn.awsli.com.br/969/969921/arq ... -4502c.pdf
It might be interesting to see how it behaves on the Arduino and start thinking about a solution to be applied to the ESP32, that's what I'm trying to do
