以STC89C52RC单片机为核心，由热电偶测量热端温度T，经过放大电路和ADC0832进行模数转换， 再由单片机进行线性化处理，最后由1602字符型LCD显示测量温度。该设计的软件由C51语言编写，采用模块化结构设计。-STC89C52RC microcontroller as the core, with hot end temperature measurement by thermocouples are amplified circuit and T, on ADC0832 frequency-field, again by microcontroller linearization processing, finally by 1602 character type LCD display measuring temperature. This design software written by C51 language, modular structure design.
