📦 基于STM32单片机的环境监测仪的设计与研究 - 免费下载

为提高对家庭环境质量的有效实时监测,及时保存相关数据,设计采用ARM Cortex-M3内核的STM32F103系列单片机为核心控制器的无线环境监测仪。使用DHT11温湿度模块、甲醛电化学模块、激光式颗粒物传感器以及GSM模块等采集室内的温度、湿度、甲醛浓度、PM2.5数值,通过嵌入式软件编程实现系统对相关数据的获取、计算和显示。通过GPRS无线通信技术,具备FTP连接主流的物联网网站,实现多机组网。经过实践系统稳定工作且性能良好,采集精确度高,可以广泛应用于家庭环境的监测。

For the purpose of improving effective real-time monitoring of the quality of family environment and saving relevant data timely,a wireless environment monitoring instrument was developed on the basis of STM32F103 series single chip microcomputers,using ARM Cortex-M3 core as key controller. The DHT11 temperature and humidity module,electrochemical formaldehyde module,laser particle sensor and GSM module were used to collect data of indoor temperature,humidity,formaldehyde concentration and PM2. 5.Acquisition,computation and display of relevant data in the system were realized through embedded software programming. Multiple computer networking was realized through GPRS wireless communication technology as well as websites of Internet of things with FTP connection mainstream. Actual application verified that the proposed system had steady operation,good performance and high acquisition accuracy,and could be applied widely in the monitoring of family environment.
