+ // SUBSTRATE CALIBRATION: You have to convert the voltage to VWC using soil or substrate specific calibration. Decagon has generic calibrations (check the 10HS manual at http://manuals.decagon.com/Manuals/13508_10HS_Web.pdf) or you can determine your own calibration. We used our own calibration for Fafard 1P (peat: perlite, Conrad Fafard, Inc., Agawam, MA)
+ float SubCalSlope = 1.1785;
+ float SubCalIntercept = -0.4938;
+ float value = moist.read(); // lee el puerto analogico y lo muestra de 0-1V
+ float VWC = value * (3.3) * SubCalSlope + SubCalIntercept; // Convert the analog reading (which goes from 0 - 1V)
+ return VWC;
