基于单片机的温湿度监控报警系统设计

The Bachelor's thesis "Design of Temperature and Humidity Monitoring Alarm System Based on Single Chip Microcomputer" focuses on the importance of temperature and humidity in various fields such as medicine, electronics, aerospace, food fermentation, and agricultural production. The thesis highlights the need for real-time monitoring and control of temperature and humidity in industries such as machinery, electronics, petroleum, and chemical. The improvement in living standards has also increased people's concerns about their living environment. The fluctuations in temperature and humidity in the air have a direct impact on human comfort and mood. Therefore, it is necessary to detect and control temperature and humidity. The use of the STC89C52 single chip microcomputer allows for the design of a temperature and humidity monitoring alarm system that can accurately and instantly respond to changes in indoor and outdoor temperature and humidity. The system provides various control methods, including temperature control within a specific range, such as heating or cooling to a specific temperature, and maintaining a constant temperature within the upper and lower limits. The same applies to humidity control. The application of this system in a greenhouse provides a more suitable environment for plant growth. For greenhouse cultivation and flower cultivation, it is necessary to install temperature and humidity devices to monitor the specific environment. This system can timely and accurately reflect the changes in indoor and outdoor temperature and humidity, satisfying the control requirements of temperature and humidity. The key words for this thesis are temperature, humidity, monitoring, STC89S52, and 2013 graduation design thesis.
