摘要
为了实现温湿度数据的采集和远程无线传输,满足偏远地区和布线困难等复杂工况下环境参量的采集需求,设计了一款基于单片机和SIM900A的无线式温湿度采集装置,详细论述了其工作原理以及软硬件设计流程。测试结果表明,该装置满足功能设计需求并具有较好的稳定性和可靠性,有较高的实用价值和应用前景。
A set of equipment prototype that able to measure environment parameters like temperature and humidity and transmit the sampled data wirelessly to a terminal was designed based on SIM900 A and MCU in this paper,for the purpose of gathering the environment parameters in working site that are too far away or too difficult to arrange the wires. The basic principle of the operation,the key points that deserves highly attention,and also the design flow in both hardware and software were discussed on in detail. Finally, the equipment prototype was proved not only to be able to meet the technical requirements well,but also had a good performance in both stability and reliability. In conclusion,it was a success to be highly useful and has a good application prospect.
