河南科技大学 本科生毕业论文（设计） 题 目 基于STC12C5410AD单片机的温湿度检测仪 二级学院 电子信息工程学院 专 业 电子信息工程 　 学生姓名 　张海宾 学 号 08104020332 年级 2008 指导教师 孙炎增 职称 讲师 教务处制表 2012 年 5 月 30 日 基于STC12C5410AD单片机的温湿度检测仪 摘 要 温湿度是环境中一个重要的物理参数，人类的生存和社会活动与温湿度密切相关。在某些行业中对温湿度的要求高温湿度检测在很多现代科技领域中成为一项重要技术STC12C5410AD单片机为核心控制器件，系统采用集温湿度传感器与A/D转换器为一体的SHT11芯片采集环境中的温湿度，模拟输入接口接入键盘实现人机交换功能，并用LCD作为显示设备的硬件设计方案。此外，在通信方面使用RS-232串行数据接口与计算机进行数据传输。软件部分则采用采用模块化的方法将其分成几个部分，然后逐模块设计程序，用汇编语言来实现，最终使各部分结合起来协调工作。 该温湿度检测仪的设计，能够完成的温湿度检测，实现主要的温湿度检测功能。 关键词：STC12C5410AD单片机，传感器，LCD，温湿度 MEASURING INSTRUMENT FOR HUMIDITY BASEED ON STC12C5410AD MICROCONTROLLER ABSTRACT The humiture is an important physics parameter of environment, human beings survival and public activities go hand in hand with the humiture. many situations that are in the production and the life, not only warehouse management, preservation of books, but also industrial production, residents life, all have certain request to the humiture of the environment, some professions have higher requirements. Therefore，it appears very important to examination and control the humiture of the environment, and humiture detecting becomes an important technology in many modern science and technology fields. In the whole design process, we have synthesized referred to the domestic and foreign similar products design method, the union users demand, as well as high Xingjian compared to and so on target, after research, used take included A/D the switch the STC12C5410AD microcontroller as the core control component, System adopts sets and humidity sensor and A/D converter for the integration of SHT11 chip microcontroller processing , and took the graphic display device with LCD the hardware design proposal. In addition, has used the RS-232 serial data connection in the serial communication aspect. But software partial uses modular the design method, causes various segments the function even more to be clear about, the r
