Capacitance method based handheld device to measure the moisture content of static grain

Abstract

Quality of the grain depends on the interna! moisture content. Capacitance method was used to determine the moisture content of static grain with accuracy of ±0.9%. This paper represents the characteristics and operation of a handheld device which was made to give real-time moisture content readings based on the capacitance of the grain with the above accuracy for paddy.
