Abstract: This paper introduces an Urine Analyzer which uses 80C552 as its master controller. Other hardware embraces PSD311,serial E2PROM24C256,Watchdog,DS1302, high quality voice synthesizer API8208,OCM320*240LCD and thermal printer M-T102,and so on. This paper also introduces the rationale of this instrument ,and module and closed mentality of designing; It adopts software and hardware to realize automatic compensation for environment temperature and luminance and urine color.The data gathering, processing, display, print and serial communication is realized; Super large-scale LCD is used as Interactive window; Real-time clock display and voice prompt; The result of measurement is quite right and the instrument is also easy to operate.
Key words: Urine Analyzer 80C552 Voice synthesizer I2C
