摘　　要：设计了一款利用步进电机驱动的指针式温度表,该温度表以AT89S52单片机为核心,辅以步进电机驱动、数字温度传感器DS18B20、LED显示、报警器等硬件电路模块组成,并对其软、硬件设计思想进行了描述.该温度表较之其他温度表具有电路简单、易于观察、抗干扰能力强、成本低等特点,可直接用于人们的日常生活,以及工农业生产中.This paper introduces a pointer thermometer driven by stepper motor. The thermometer meter mainly consists of MCU AT89S52 as the core of the meter, stepper motor ,digital temperature sensor DS18B20, LED, annunciator and so on. This paper also presents in details the designing thought of the temperature meter＇s software and hardware. The temperature meter has many characteristics , i. e, high accuracy, small error, better capacity of resisting disturbances and so on. It can be directly used in people＇s daily life and in industrial and agricultural production.
