Temperature and humidity are two of the most basic environmental parameters， people living and temperature and humidity are closely related. In the daily life， industry， medicine， environmental protection， chemical， oil and other fields， often need to measure the ambient temperature and humidity and control. Accurate measurement of temperature and humidity in the bio-pharmaceutical food processing， paper and other industries is essential. Therefore， the study of temperature and humidity measurement methods and devices have important significance. With the continuous development of science and technology， SCM technology has been popular to our work， life， research and other fields. Has become a more mature technology. Because of the high integration of single-chip， strong function， high reliability， small size， low power consumption， easy to use， etc.， has now penetrated into our work and life in all aspects.

This topic is a design topic， requiring students to understand the development of embedded single-chip system development process， functional analysis， circuit selection and hardware and software design. Requires STM32 microcontroller development board as the core for temperature and humidity monitor design. Training students with the initial development of single-chip system design capabilities.
