Hi everybody,
The project gets real… I am looking fortwarfst to getting some p.linkei soon.
Now I am preparing the tank. I had an interesting conversation with my chemistry teacher and he gave me two sensors and a mainboard of the Pasco-Systems that is used in our School. Today, I testen some RO water and water from the tank for pH and EC.
The results seem to be convenient. I have Measured RO water pH 6.98 EC 0 microsim/sec.
The has pH 5.02 EC 14
What Do you think about the Sensors and the recults? Does anyone know the Pascosystem? Are These good Sensors?
