Hey guys,
Im back asking for more help. So I have a reef pi setup currently with a PWM controller controlling two lights for my fresh water setup. I want to add a PH probe to my setup.
I bought the Atlas PH probe circuit- https://atlas-scientific.com/embedded-solutions/ezo-ph-circuit/
Atlas Mini-PH Probe- https://atlas-scientific.com/probes/mini-ph-probe/
And Atlas Carrier Board- https://atlas-scientific.com/carrier-boards/electrically-isolated-ezo-carrier-board-gen-2/
I have followed the outdated guide- https://learn.adafruit.com/reef-pi-guide-7-ph-monitoring?view=all
So here is the issues im running into. I can not get the raspberry pi to see the sensor. I have it connected in parallel to my PWM controller and trying to read it using I2C. It will see the PWM IF i have the PH disconnected. If Both are connected the Pi wont see either or itll only see address 40 of the PWM controller.
Once I was able to get it to see both sensors via I2C. So I then tried to follow the guide and set the sensor up on Reef Pi i run into my next issue. When I go to the PH tab and click the plus button, the Analog Input drop down shows nothing. Do i need to create a driver like I did with the PWM controller?
I have also tried wiring it up as TX to Tx and Rx to Rx, as well as TX-Rx and Rx-Tx. Once again the Analog input doesnt show anything.
What am I missing?
Thanks!
