Abstract：A new type of photoelectric small-invasive blood glucose monitor was developed. This instrument is based on a 16 bit microprocessor MSP430F413 which belongs to a low-power microprocessor of the component family of Texas Instruments promotion recently. There are three advantages of this instrument: (1) using the method of two optical beams to decrease the influence of the LED’s power fluctuation, (2) using the multiple comparative method to determine the terminative time of enzymatic reaction and the start time of computing and processing, (3) to store a lot of measured data up to 50 samples. The data measured by this instrument were compared with Prestige blood glucose monitor, and the result shows that the accuracy and the reliability of this instrument is better. The specialties of this instrument are easy operation, getting results quickly, low-power and low cost. It is an ideal instrument for diabetic test and control of blood glucose concentration at home.
