"基于AT89S52单片机的仓库温湿度检测系统设计与实现"

Thesis Summary: This thesis presents the design and implementation of a warehouse temperature and humidity detection system based on the AT89S52 microcontroller. The system is designed to automatically detect and monitor the temperature and humidity levels in a warehouse environment. The hardware components of the system include the control circuit, temperature acquisition circuit, humidity acquisition circuit, keyboard, and LED display circuit. These components work together to collect data on the temperature and humidity levels in the warehouse and display the information on the LED screen. The software design of the system is based on a systematic approach, starting from the design concept and software system diagram. Each module's program algorithm is analyzed and implemented to meet the requirements of the task. The final program is written to effectively detect and monitor temperature and humidity levels in the warehouse, as well as trigger appropriate alarms when necessary. The system is designed to have several advantages, including minimal overshoot, accurate sampling values, and simplicity of operation. It effectively meets the requirements of temperature and humidity detection and alarm, providing a reliable monitoring system for warehouse environments. Keywords: AT89S52, LED display, humidity detection system.
