Wifi module afficting ph probe reading

Post by acabano13 »

Hi,

I have been observing my pH reading is fluctuating and reads higher when my WIFI module is plugin.
and it is causing my kalk dosing port relay to switch on/off .
I was able to confirm via removing the WIFI module, any help is greatly appreciated, ty

It sounds like electrical noise or grounding issue possibly. I would make sure the pins are all clean, and the cable pins all have a good connection.

Did this just recently start since the migration?

[acabano13] - no sign of corrosion on the pins, cleaned it any but same result.

[acabano13] - yeah i have not observe the issue before but i could be wrong, any recommendation for a pH probe?


Thanks.

I prefer Atlas Scientific. I don't use their PH probe (don't does anything, just observing so I don't need the accuracy) but I do use their salinity probe.
