Communication function test with co

Communication function test with computer connection. The temperature and humidity meter can carry out data communication with the upper computer of the computer, and can transmit the collected temperature and humidity values to the upper computer of the computer for display through MAX232. Click Run in the upper left corner of LabVIEW to pop up a run interface. In this interface, the left side is the temperature and humidity curve, and the right side is the current temperature value, upper temperature value, lower temperature value, current humidity value, upper humidity value and lower humidity value from top to bottom. First change the serial port number in the lower right corner, and click "start acquisition" in the lower right corner. At this time, you can see that the temperature and humidity curve starts to move normally, and the temperature and humidity values are displayed in real time on the right side.
