| Abstract: | A kind of portable and fast blood glucose meter is introduced.This instrument is based on amperometric biosensor's enzyme electrode—glucose oxidase electrode and MCU STC12C5410AD.The operation principle,the hardware electric circuit of functional blocks and the software design of main program are described in detail.Besides,the temperature survey circuit and the real-time circurt are described concretely.The measurement range of glucose is 1.1~33.3mmol/L.The coefficient of variation(CV) is less than 3%.The detection result can be available in no more than 5s.The 180-group historical data can be stored.The testing temperature range is from 10~45℃ and temperature compensation and automatic rectification are applied in this meter. |
