A working prototype for humidity measurement, designed in real conditions, allowing to measure soil humidity with less than 10% error.
The research was performed with different soil types, whose electric characteristics were measured by using a finite element method, simulated and optimized using interlocked electrode sensors and chip AD5933 for impedance measurement.
The developed device will help to identify clay-type soils by the humidity parameter, with reference to the quantitative index of this parameter. This is relevant for clay-type soils with higher humidity.
