•   EC-5 Decagon   Decagon The sensor delivers a 

voltage x[mV] that the H2O transmitter transforms 
into VWC [%] (Volumetric Water Content or Soil 
Water Content) using the following expression: 
VWC [%] = bx+a, and according to soil type: 

 

‒ Mineral soil:

 

∙ a = -0.48

 

∙ b = +11.605E-4

 

‒ Potting soil:

 

∙ a = -0.696

 

∙ b = +17.749E-4

The value, in [%], is converted, by the transmitter 

itself, to standard 4-20 mA current (800-4000 mV in 

Agrónic format), so that the controller in question 
must select the Ideal data format according to the 

type of sensor and type of soil selected. It is the res-
ponsibility of the user to change the data that charac-
terizes said format.

•   TEROS-10 Meter Group   The sensor delivers a 

voltage x[mV] that the H2O transmitter transforms 
into VWC [%] (Volumetric Water Content or Soil 
Water Content) using the following expression: 
VWC [%] = dx3+cx2+bx+a , and according to the 
soil type: 

 

‒ Mineral soil:

 

∙ a = -2.154

 

∙ b = +3.898E-3

 

∙ c = -2.278E-6

 

∙ d = +4.824E-10

 

‒ Potting soil:

 

∙ a =  -2.683

 

∙ b = +4.868E-3

 

∙ c = -2.731E-6

 

∙ d = +5.439E-10

The value in [%] is converted, by the transmitter itself, to standard 4-20 mA current (800-4000 

mV in Agrónic format), so that, in the controller in question, it is necessary to select the Ideal 
data format according to the type of sensor and type of soil selected. It is the responsibility of the 
user to change the data that characterizes said format.
