Hi, I was wondering if it was possible to design a raspberry pi to monitor the value within a marine fish tank. It wouldn't have to measure specific values as such but possibly more a variation of what would be the calibration solution (natural seawater). Basically from the variation i you could decide a water change is needed. Would this still need to measure each specific value ? If the later is it possible to probe or sensor the following ?
Calcium - in ppm
Alkalinity - in dKH
Salinity - in ppt or sg
PH -
Magnesium - in ppm
Phosphate - in ppm
I appreciate there will be alot of coding required but there is also alot around to help.
Sorry i hope this makes sense i have very limited knowledge in this field but i am still reading and learing about the possibilities ! Any help is appreciated.
