摘要
温度是日常生活和工程实践中的一个重要参数,文章设计了一种温度采集系统,该系统以STM32单片机为主控制器,AD590为温度传感器。首先,系统通过AD590温度传感器采集温度信号,AD590内部将此温度信号转换成电流信号输出,然后通过一个采样电阻将该电流信号转换为电压信号。其次,系统将电压信号送入滤波放大电路中进行放大处理,之后送入STM32的ADC进行处理,得到温度数据。最后,单片机将此温度数据显示在LCD显示屏上。实践证明,该系统测量误差较小,可以满足日常的实验要求。
Temperature is an important parameter in daily life and engineering practice. In this paper, a temperature measurement system is designed with STM32 microcontroller as the main controller and AD590 as the temperature sensor. The simple temperature acquisition system can convert the real-time collected temperature signal into voltage signal and display it on the LCD screen. Practice has proved that the measurement error of the system is small, which can meet the daily experimental requirements.
