EC Sensor Calibration Equations
Account cancelled 2018-07-04 21:13:25 1762 Views1 Replies Hi,
maybe you can give me an explanation. It would be very helpful. I've bought the Analog electrical conductivity sensor.
I want to calibrate my EC Probe with the code from the wiki and the Sheme of calibration.
My question is now, how are the three equations are calculated out?
Do I need to change the equations with the results of my calibration progress?
And how can I do this?
What are those Values in this three equations? Like 6.84 or 64.32?
It would be nice, when i could get an answer how this is calculated out.
Thanks for your help in advance.

Code: Select all
if(CoefficientVolatge<=448)ECcurrent=6.84*CoefficientVolatge-64.32; //1ms/cm<EC<=3ms/cm
else if(CoefficientVolatge<=1457)ECcurrent=6.98*CoefficientVolatge-127; //3ms/cm<EC<=10ms/cm
else ECcurrent=5.3*CoefficientVolatge+2278; //10ms/cm<EC<20ms/cmThanks for your help in advance.
