用51单片机控制AD，测量室温，并用串口上传到上位机，绘出温度曲线图。-MCU with 51 AD, measured at room temperature, and uploaded to the PC with a serial port, draw the temperature profile.

温室读折线图曲线图，读取温湿度后直接显示在上位机界面上。-Greenhouse read line graph curve, read the temperature and humidity displayed directly on the PC interface.

vb 利用串口读取单片机传送来的数据，并在VB上上曲线图动态显示(文档内含VB代码,单片机代码，说明文档)-vb use microcontroller serial port to read the data transferred, and on the graph in VB dynamic display (the document containing VB code, the microcontroller code, documentation)
