Hi, my current code is below. They're still a working area in it! Especially the code in the field void onConnectionEstablished. I faced later that Arduino saves the code every time I compile it, that why there some changes from last time to it. What I like to do later on is to move calibration (thi...

Hi,

I like sensors where the electronics are encapsulated. I remember to this here

It is expensive, but looks reliable.

Hi Barcardi, for the wiring of ESP32 with ADC11x5, I found this youtube video useful: https://www.youtube.com/watch?v=XxUMc1jnI9U&t=122s . I use DFRobot Probe and the following library helped me get it done. https://github.com/GreenPonik/DFRobot_ESP_PH_WITH_ADC_BY_GREENPONIK . (I use SEN0169.) I had...

Dears,

Thanks a lot to all of you. Only with your information, I was able to build my control box.

I purchase Adafriut peristaltic pump (1150). I also had to adjust the value to 1300. I wait for the final parts of my housing and assembly of everything once got it.

Hi, I was searching for a way for a graphical showing of my ph value. As Lovelace was not offering so many options I searched and found a mini graph card addon. It is from HACS. As I found nothing on my search I like to share it herewith to you. I set it up and now my card in Lovelace looks like thi...

Hey Barcardi,

I would assume the resolution of the ADC from the ESP32 is not high enough. You can give a separate ADC a try. I use ads1115 and it works with DFrobot SEN0169 and ESP32. Also, I have a temperature sensor on it too, it is important for calculating the correct ph.

Hi, without any detail, it is difficult to provide you an answer. At least what kind of code you use and what you have tried so far would be nice to know. I use ESP32 with SEN0169. There are some examples at GitHub. I used greenponik together with additional ADC. I posted my code here: https://ledga...

Hi, Thanks for the post above. This was helping me to understand the System interactions. I was playing last week a bit around. I found "mysensor" and this was very interesting to me. But not was I searching for. My last programming was BASIC. After getting some understanding of C I change the code....

Thanks a lot!

I was experimenting with some code, so step by step.

I will try next weekend.


Best Regards

Hello, I set up an ESP32 with the ADS1115, PH, and Temperature probe. Works find and calibration too. I used the greenponik code on Github. #include <Arduino.h> #include "DFRobot_ESP_PH_WITH_ADC.h" #include "OneWire.h" #include "DallasTemperature.h" #include "Adafruit_ADS1015.h" #include "EEPROM.h" ...
