摘要
使用AT89S52单片机作为主控芯片,通过温度传感器DS18B20采集温度送入单片机进行处理,将处理好的数据通过RS232串口送往上位机PC,上位机利用获得的数据绘制温度曲线图,便于直观地进行温度监控工作.系统还可以扩充为多路温度数据采集系统.
By using the temperature sensor DS18B20 to collect temperature data and the microcontroller AT89S52 as the core component,data was transmitted for procession.Via RS232 serial port,the processed data was sent to PC to draw out temperature curve for directly monitoring the temperature.The system can be also expanded to multi-channel temperature data acquisition system.
