Dosing pumps and PH

I was thinking about this tonight, is there a way to set the dosing pumps NOT to run if the PH is at 8.20 and if it should drop below 8.0 to have them start running again?

yeah
You need to declare a new variable to hold the status for the dosing.
Place this above setup:
Then use this on the loop:
Code: Select all
if (ReefAngel.Params.PH<=800) CanDose=true;
if (ReefAngel.Params.PH>=820) CanDose=false;
if (CanDose)
{
// Insert your dosing function here
}
Try this and let me know if it works for you.

Yeah, if you look at your code, there is basically 3 sections.
The first is the one with a bunch of .h header files
The second is a setup() function
The third is a loop() function
So, yes anywhere above setup or just below the .h file is fine.
