Abstract— This work present a low cost soil moisture sensor
based on impedance spectroscopy by means of magnitude ratio
and phase difference detection method. For this purpose, a probe
which uses a simpliried impedance measuring system to
determine soil water content has been designed. The circuit
sweeps at pre-programmed frequencies from 10 KHz to lOMHz
with lOmVac amplitude. A local inceptisol soil of East Sumatra
was especially selected for this investigatioa because
measurements of soil moisture in peat swamp area were generally
reported as difficult ones. A sample at defined soil moisture of
2%, %"/», 15% measured using commercial soil sensor Lutron
PMS-7i4 was characterized. A corrected model has been
developed in order to reject the frequency influence upon the
measurement. The results obtained by the sensor show good
results with an overall mean error of0.207% in impedance. |
