ph sensor

[MrThiemann]

hey,
First of all, thank you for this great post! it helps me a lot with my pool control!!
I have the same pH sensor as you, but have enormous difficulties integrating it with me.
I'm either missing it or it's not there: your code for the sensor.

I've really tried quite a few things.. with "attenuation"... or without. times on auto and now on 11db.
I once had the sensor at 3.3 V and now at 5 - but somehow that doesn't want to.

could you help me

- platform: adc
   attenuation: 11db
   pin: GPIO34
   name: "PHSensor"
   update_interval: 1s
   unit_of_measurement: "pH"
   icon: "mdi:water-percent"
