So I have a 5v analog ph module and a DF Robot EC meter, both are being read using the " ADS1115: Generic Analog pH/EC" input type. As you know the introduction of the EC meter affects PH, so how are you guys measuring this? Do I have to set it up so the EC meter can be turned on via a GPIO pin with a 2n222 transistor once X amount of time and then polled? Im curious how everyone else is getting around this issue.

The proper way to do this is with an isolator module. See:
Thank you. BTW, I freaking LOVE your software man. I looked for months on what to build and was happy I came across your youtube video.

Late to the party, I’m trying to use the Atlas EZO- EC sensor but I can’t for the life of me change if from UART to I2C… “Pulling my hair”
Manual switching to I2C
Disconnect ground (power off)
Disconnect TX and RX
Connect TX to the right PRB
Confirm RX is disconnected
Connect ground (power on)
Wait for LED to change from Green to Blue
Disconnect ground (power off)
Reconnect all data and power
