we are using the SEN0161 v1 from (Analog PH Sensor) DFRobot.
The sensor gives correct reading when tested with the provided buffer / testing liquids, but gives wrong readings when put in the aquaponics water.
We know the water is not that basic due to another PH chemical tester we have for comparaison.
We are using the probe with an ADS1115 adc module, in conjuction with another EC probe, which behaves correctly.
Thanks in advance for your help!
