【摘要】：对温湿度进行精确的测量和控制是目前工、农业等领域一项重要的研究技术，以往在这个领域我们使用的技术都很落后，测量方法也十分粗糙。科技的高速发展以及智能技术的出现促使温湿度采集技术在这些年有了长足进步。温湿度检测设备正从传统的干湿球、普通计量器向小型化、低功耗、高智能的领域不断发展，这为研发新一代温湿度传感器系统提供了充足的条件。传统的温湿度检测设备要么根本就没有数据存储元件，要么就是由8位单片机构成，运行程序简单，存储数据十分有限。基于现有温湿度传感器的诸多缺点和不足，提出设计一种新型温湿度传感器。以往的便携式温湿度记录器大多采用性能较为落后的单片机作为其硬件平台，程序效率低、功能单一，同时还需要大量外围器件来支持其进行功能扩展。并且由于使用外围元器件过多，还导致功率消耗大，体积偏大等诸多缺点。本次设计中我们选用了基于Cortex-M3内核的STM32平台，与传统温湿度传感器常常采用的单片机相比较，极大的提高了运行效率，小型化的发展理念使得其集成了大量的高效外设，其程序大多实现模块化，接口简单，，极大的缩短了开发程序的周期，减少了外围电路。
[Abstract]:Accurate measurement and control of temperature and humidity is an important research technology in the fields of industry, agriculture and so on. In the past, the technology we used in this field is very backward. Measurement methods are also very rough. The rapid development of science and technology and the emergence of intelligent technology has made great progress in temperature and humidity acquisition technology in recent years. Temperature and humidity detection equipment is from the traditional wet and dry bulb. The development of ordinary metering devices in the fields of miniaturization, low power consumption and high intelligence provides sufficient conditions for the development of a new generation of temperature and humidity sensor systems. The traditional temperature and humidity detection equipment either does not have data storage element at all or is composed of 8-bit single chip microcomputer. The operation procedure is simple. The storage data is very limited. Based on the shortcomings and shortcomings of the existing temperature and humidity sensors, a new type of temperature and humidity sensor is proposed. In the past, the portable temperature and humidity recorder mostly used the single-chip microcomputer with backward performance as its hardware platform, the program efficiency is low, the function is single. At the same time, a large number of peripheral devices are needed to support the functional expansion, and because of excessive use of peripheral components, it also leads to high power consumption. In this design, we choose the STM32 platform based on Cortex-M3 kernel, which is compared with the traditional temperature and humidity sensor. Greatly improve the operational efficiency, miniaturization of the development of the concept of integration of a large number of efficient peripherals, most of its programs to achieve modularization, simple interface, greatly shorten the development process cycle. Reduced peripheral circuits.
