Hi @boilermanc,

You could refer to this Wio Terminal pinout:

1920×1560

And make the connections with the ph-4502c sensor as follows:

PO of sensor ==> Pin 13 of Wio (A0)
VCC of sensor ==> Pin 2 of Wio (5V)
GND for PH probe of sensor ==> Pin 6 of Wio (GND)
GND for board of sensor ==> Pin 9 of Wio (GND)

Hope it helps.

Best Regards,
Lakshantha
