Interpretive Summary:

Technical Abstract: The objective of this study is to assess the performance of a select sensor in measuring moisture content of cotton within the moisture range of 6%-13%. It is the first step in developing a system to monitor moisture in real time in the ginning environment with a long-term goal of developing a closed loop system in which cotton moisture may be maintained optimally throughout the ginning. The assessment was carried out in two phases: static (cotton velocity = 0) and dynamic (in-stream). During the static testing phase, models to predict moisture content were created and a 95% Confidence Interval of [-0.619,0.619], Percent Residual Accuracy of 97.586%, and a mean error of 4.396% were achieved. The tests were done with 110 samples. The Bland-Altman plot yielded a curve with a slight positive trend, suggesting that the data could be modeled more appropriately by multiple models with each predicting a narrow range of moisture contents. The dynamic testing phase saw similar results as the static tests in overall trends, however the predicted values tended to be less accurate than in static testing. Static testing had a RMSE of 0.313 compared to the dynamic testing having a RMSE of 0.737 [MC%]. This may stem from the relatively low number of data points collected during the dynamic test as compared to the amount of data collected in the static phase.
