用单片数字温度计IC DS1620测量温度,其测量范围为-55～+125℃,分辨率为0.5℃。如图所示,采用PC机的打印接口与ICDS1620联网(通信),将C程序(见附表)通过打印接口给ICDS1620再送控制指令,就可从ICDS1620中读出测量数据。变换该数据成温度值,可在显示器上显示
The temperature is measured with the monolithic digital thermometer IC DS1620 with a measurement range of -55 to + 125 ° C and a resolution of 0.5 ° C. As shown in the figure, the measurement data can be read out from the ICDS1620 by using the PC printer interface to communicate with the ICDS1620 (communication) and send the C program (see the attached table) to the ICDS1620 through the print interface to send control commands. Transform the data into a temperature value that can be displayed on the display
