Doubts with hardware [SOLVED]

[Jean Carlo]

I'm new to the forum. I'm from Brazil and my English is not very good.
I found the project very interesting and would like to know if there are more affordable alternatives for these boards https://atlas-scientific.com/embedded-s ... y-circuit/ and the others as well.
Has anyone already used this PH https://produto.mercadolivre.com.br/MLB ... rasppi-_JM

Hi!

Welcome Jean!

I have no experience with any pH circuit other than from Atlas Scientific.

You can use any cheap pH circuit compatible with Arduino but you have to adjust Ferduino code by yourself.

The only help you will get from me about this part is available here.

Just pay attention that the variable "Stamps" doesn't exists anymore. Instead you should comment out this two variables:

Code: Select all

//#define STAMPS_V4X
// #define STAMPS_EZO

Best regards.

A little bit more of information since code structure has changed.

To edit the code you should use Atom or VSCode with PlatformIO extension.

Here you can find a tutorial to work with Atom.

Watch on youtube.com

To add the function void readPh() you should create a new file like "my_pH_Circuit.h" inside of Modules folder.

Then in the end of Ferduino_Aquarium_Controller.cpp file add:

Code: Select all

#include "Modules/my_pH_Circuit.h"

This variables can be placed in Configuration.h:

Code: Select all

#define SensorPin A0            //pH meter Analog output to Arduino Analog Input 14
#define Offset 0.00            //deviation compensate
int pHArray[10];   //Store the average value of the sensor feedback
int pHArrayIndex = 0;   
float pHValue;
unsigned long samplingTime = 0;
unsigned long samplingTime1 = 0;
byte samples = 0;

Tanks Fernando
I'm going to search for more affordable alternatives on these three plates. I'm first trying to find everything I need on aliexpress the only knowledge I have is web programming and I understand a bit of csharp.

I didn't find any Arduino board to measure salinity on aliexpress

Hi!

I think the initial question was answered so I will close this topic.

Best regards.
