The study of the agricultural product storage temperature and humidity control system

In order to solve the low accuracy, real-time performance and system scalability problem of agricultural product storage temperature and humidity control, we proposed and implemented an economical and practical temperature and humidity control solution. It mainly consists of 8098 single chip microcomputer, 8255 parallel interface circuit, temperature and humidity sensor and transmitter, drive circuit, alarm and show circuit. We conducted the system test and application for needle mushroom agricultural products after the system finished. We controlled the temperature and humidity within the limits prescribed, showing the current temperature and humidity by the display so as to achieve the purpose of controlling the agricultural products storage temperature and humidity within the optimum range. The experiments show that the system is of low cost, high precision and has improved production efficiency to some extent.
