Abstract: A detection system of a shortage in tobacco box based on capacitive sensor array using AD7745 is proposed in this paper. The system consists of a master MCU C8051F020 and some slave MCUs C8051F310. The master and slave MCUs are communicated by SPI bus. The slave MCU is connected to AD7745 through SMBUS. Measurement results show that the detection effect of system is reliable.
