Moisture Determination of Cotton in Static Conditions Via Capacitive Sensing

This project aims to develop a reliable means to measure cotton moisture content in real time via capacitive sensing during the pneumatic conveying process. In this phase of the project the capacitive sensor was calibrated and a method of converting the sensor’s output (mA) to moisture content was developed. The reliability of the capacitive sensor was determined as well as what effect varying the amount of coverage of cotton on the sensing face would have on the measured current of a single cotton sample.
