WANG Wei ^[14] | HUANG Xin ^[2] | WANG Li ^[15]

Abstract: Based on the temperature and humidity requirements of the archive warehouse, this paper designs an archive warehouse monitoring system based on the STC89C52 microcontroller to monitor the temperature and humidity of the archive warehouse in real time. When the real-time temperature and humidity exceed the set corresponding threshold, the system will alarm. The designed system is composed of sensor module, microcontroller module, liquid crystal display module, sound and light alarm module. STC80C52 microcontroller is the control core of the system, using temperature and humidity sensors to collect temperature and humidity data in the warehouse. The temperature and humidity sensor sends the collected data to the microcontroller for processing, and displays the temperature and humidity on the LCD screen. The system uses Keil software to write programs, and uses Proteus software to perform simulation tests to realize the real-time display of temperature and humidity, and realize the alarm function when the temperature and humidity exceed the set threshold.
