APPLICATION OF STATISTICAL TECHNIQUES FOR TESTING SOIL MOISTURE MEASUREMENT WITH STAINLESS STEEL TUBE SENSORS

Soil moisture measurement with advanced analytical tools is expensive and complicated. A simple soil moisture sensor was created using the capacitance between two parallel rods, which can be measured using stainless steel tubes. The statistical significance of differences in measurement testing requires studies. In this work, we introduced analysis of variance and correlation approaches to assess the statistical significance of differences between systematic effects and errors resulting from environmental parameter variation. Comparisons of the obtained results with effects and errors resulting from environmental parameter variation data on the capacitance between the two parallel rod sensors were presented. This statistically significant approach contributes to efficient and low-cost estimations of soil moisture and understandings of soil moisture based on environmental parameters.
