摘　　要：研制了一种新型便携式烟丝水分测定仪.测定采用电容法原理.样品通过先进的传感器检测后,信号经过A/D转换器和单片微机数据处理系统,以数字显示测得的水分、温度、重量数据。仪器能进行温度和重量的自动补偿,并具有掉电保护、自动查询故障功能.介绍了硬件和接口电路及软件设计。A novel portable tobacco shred moisture meter based on capacitance method was designed. After samples are tested by an advanced transducer the output signals are transfered to the A/D converter and dataprocessing system. The values of moisture, temperature and weight are displayed on a liquid-crystel digital display. Changes in temperature and weight of samples can be compensated automatically. The hardware and interface circuits and software design are described.
