在生活的实际生产在许多情况下是要考虑温度和湿度环境和精确控制的影响，如粮食储存和烟草生产，控制自动空调，车载等。

由于集成电路制造技术的不断提高，高性能，高可靠性的单片DAS数据采集系统的出现。数据采集技术已经成为一种专门的技术，在工业领域得到了泛的应用，数据采集系统采用更先进的模块式结构，可根据通过简单的增加和改变模块的不同的应用需求，并与系统编程相结合，可以扩大或修改系统，迅速 ​ ​ 组成一个新的应用温湿度数据采集系统始终是有关科研单位和公司致力于开发项目，其早期的系统在单片计算机8031核心，采用热敏电阻和湿敏电容作为温度传感器和湿度传感器，整个系统，同时成本低，但大尺寸和精度低，限制通信距离，普遍性较差，为了克服缺点的基础上，温湿度数据采集系统的单芯片处理器本文的研究，实现对温湿度监控仓库的房间场景，有实时性好，精度高，操作简单，方便，信号收发器维修方便的优点。-In the actual production of life in many cases are to consider　 the　 influence　 of　 temperature　 and　 humidity environment and precise control, such as food storage and tobacco production, automatically control of air conditioning, car etc.Because of IC manufacturing technology unceasing enhancement, The emergence of a high performance, high reliability single-chip DAS data acquisition system. Data collection technology has become a specialized technical, in the industrial fields have been extensively applied, data acquisition system USES more advanced module type structure, according to the different application requirements through simple increase and changed module, and combining with the system programming, can expand or modifY system, quickly composed a new system [ll.

Temperature and humidity data acquisition system is always relevant scientific research units and the company committed to developing project, its early system in monolithic computer 8031 core, using thermist
