Interaction between pH, EC, and Redox sensors?

LukasB

Hello,

we have connected a pH, EC, and Redox sensor to our Arduino, however the system shuts down every other day and we need to restart it by unplugging it for a few seconds. We suspect that the sensors (which are constantly submerged in water next to each other) influence each other and cause this shut down. 

Is that possible? If yes, why?

Kind regards,

Lukas

    What diagnostic steps have you taken to come to that conclusion ?

    Have you tried running the system with only one and two sensor(s) active at a time ?

    What makes you think that it is a sensor issue rather than a programming issue ?

    When you say 'shut down' what do you mean ? Is the system programmed to shut down given a specific condition ? or are you perhaps assuming that the Arduino program has stopped running because it isn't outputting anything visible ? e.g. it may still be running but just in an infinite loop that doesn't output anything.
