Practically, all properties of agricultural crops depend on moisture content. A new parallel plate capacitance sensor was built to relate the moisture content and dielectric properties of sugarcane stalks. The results revealed a relatively strong quadratic relationship between the moisture content on green weight basis of sugarcane material put through the plates of sensor and the measured voltage (mV) by capacitance sensor circuit output. The coefficient of determination (R2) was 0.91. Some other samples were used to test the results and there was a high correlation between calibrating and testing samples for the device and the coefficient of determination (R2) was found to be 0.95. More research is suggested for improving the electronic circuit and investigation about the sensor type is suggested.
