Abstract：Since powder and cotton wool may cause mechanical test fail, and the accuracy of ray detection method is not very ideal, this paper introduces the tiny capacitance detection method for broken gunpowder, in which the medium type capacitive sensor's capacitance changes when the gunpowder core diameter changes. The detection is based on the relationship between non-electric quantity and electric quantity. Simulation results show that the designed system works well with easy installation and low power consumption. Therefore, it is suitable for broken gunpowder detection.
