With the rapid increase of global population, energy consumption is increasing day by day. Therefore, it is very important to use some infinitely renewable energy to replace the slow and non-renewable energy. Solar energy is one of the infinitely renewable energy sources. In this paper, the lower computer design USES STC89C52RC as the main control chip to complete data collection. The upper computer design is a virtual solar refrigeration monitoring system built based on LabVIEW. Through serial port communication, the upper computer is connected with the lower computer to realize real-time monitoring, data storage, automatic control and alarm of temperature and humidity in the environment. The test results show that the temperature accuracy of the system is 0.5, and the resolution is 0.1℃. Humidity accuracy level is 0.5, resolution is 1%RH, the whole solar refrigeration monitoring system operates normally.
